Cooling water treatment – Increase and maintain efficiency of you industrial HVAC cooling system

Cooling water treatment can be quite a mystery. This treatment type is essential, particularly if companies want to maintain and increase their industrial HVAC cooling system. The old proverb, “out of sight, out of mind” is a common philosophy of numerous industrial building owners. This attitude ascends in part mainly due to the internal part of the equipment and piping infrastructure that cannot be easily inspected or seen.

In addition, there are plenty of less-than-trustworthy water-treatment companies selling infective or costly water-treatment equipment and chemicals, which can discourage engineering and maintenance managers from cultivating an effective water-treatment program. Water treatment is deemed as the best insurance for shielding major investments in a buildings’ cooling and heating infrastructure.

If left untreated, water systems can swiftly cause expensive damage. A successful cooling water treatment program for industrial HVAC and portable water systems is compulsory to maintaining the energy proficiency of equipment, to shield building occupants, and to guard the equipment from corrosion and scale.

The Evolution of the Industry

In the last 15 to 20 years, the water-treatment industry has altered substantially, as many companies have pursued instantaneous profit gains through acquisitions and mergers. Currently, there are more than five major companies that provide water-cooling treatment throughout the entire country. Environmental guidelines have also changed the technology utilized in the cooling water treatment industry.

Most cooling-tower systems utilize molbydates and phosphates versus chromate-based inhibitors that were very popular many years ago in controlling corrosion and scale. The latest outbreaks of Legionella have elevated the level of analysis of water-treatment solutions for HVAC systems, spas, cooling waters, portable-water systems, and other fragments of systems that are prone to the breeding of bacteria.

Starting the Program

A majority of commercial and institutional facilities have recognized that developing a strong relationship with cooling water treatment companies is just as crucial as the treatment itself. Choosing a highly reputable company to help with the treatment of cooling water for the HVAC is essential.

Engineering and maintenance managers should regard the association as a partnership where they can discuss openly and assess new water-treatment technologies in order to decide which one is the best option for their HVAC systems. Some managers view several new water-treatment technologies akin to snake oil. However, through proper partnership, they can avert potential calamities from the newest and greatest ideas.

Once a water-treatment company is chosen, building owners should run a raw water analysis. This is a required step in order to construct a cooling water program that is appropriate for their buildings. By conducting a raw water analysis and governing a system’s operational hours, operating temperature, and load factor, a cooling water treatment specialist can regulate the chemicals, equipment, and monitor the program.

To maintain and increase the cooling system of all the HVAC systems, it is not advisable to base the treatment, according to other buildings in the vicinity, given that local water sources and equipment can differ. Additionally, all buildings’ operational hours are usually different.

Benefits of a solid solution green water treatment system

Wastewater treatment and management have become hot-button issues in every facet of building, zoning and LEED certification. Having the ability to treat wastewater in a closed system makes recirculation more efficient, saves water and energy and reduces contaminant loads in public sewers and watersheds. Until recently, a single-stage, integrated solution for internal wastewater simply did not exist, necessitating costly retrofits to existing systems to bring them into compliance.

A Solid Solutions(R) Green Water Treatment system reduces or eliminates the need for multistage wastewater treatment, reducing cost and amplifying the efficiency of both existing and custom-build water management designs. This single-stage, multichemical system is designed to integrated into virtually any system with the simple addition of a dilution panel and reservoir between a normal tap water influent line and the metering pump. The influent line interacts with the solid chemical in the reservoir to release a concentrated water purifying mixture into the system for treatment and recirculation.

The system is designed to integrate with most cooling, boiler and closed-loop recirculating water applications quickly and easily, minimizing downtime and maximizing system efficiency. Some of the benefits of this system are:

  • It is designed for simple, fast installation and implementation.
  • No chemicals to mix or handle. Simply load a one-gallon, 50lb container into the dilution panel and walk away. Handling an empty container is as easy as pull and replace.
  • Each gallon of dry Solid Solutions(R) Green Water Treatment yields 30-55 gallons of treatment, meaning no need to store or dispose of bulky drums or risk potential injury hazards from moving or mixing contents of the drums. This also increases storage area for other necessary parts and equipment, reducing congestion and work area hazards.
  • The dry chemical is a multi-stage, environmentally intelligent treatment including microbiocides, corrosion inhibitors and dispersal agents to increase closed-system treatment efficiency.
  • Each carton is packaged in HDPE-2 recyclable plastic and fiberboard for easy recycling.
  • This product qualifies for LEED credits and helps attain or increase existing LEED certifications up to platinum level, depending on other aspects of the system.
  • The operational cost of this system is comparable to traditional drum-based liquid treatments, but requires far less personnel time and oversight, freeing employee time for other tasks and reducing chances of injury.
  • Solid Solutions(R) Green Water Treatment is designed to be easily soluble with nothing more than room-temperature tap water, taking the guesswork and hassle out of recirculating water treatment. This translates to large savings in labor costs and compromised storage space, freeing essential personnel and storage for more critical tasks. The efficiency and labor savings alone over the system’s lifespan would make this solid treatment an excellent leading treatment candidate, but adding the benefits of more effective results with a lower chemical load makes Solid Solutions(R) Green Water Treatment well worth examining more closely for nearly any closed-loop recirculating water system. Finally, the LEED Silver, Gold and Platinum certifications to which this system can enhance existing internal wastewater treatment make this a safe, sustainable choice for your treatment applications.

What Is the Verox-8 Cooling Water Treatment System?

A versatile broad-spectrum microbiocide, chlorine dioxide is well known for its effectiveness in controlling a host of microorganisms that grow in cooling water systems. Fungi, algae and bacteria flourish in conditions that don’t favor chlorine or other organic-based proprietary products. However, Verox-8, a concentrated solution of stabilized chlorine dioxide, is being used with favorable results as a control for microbiologic growth in water treatment systems, and in particular, under conditions not favorable to chlorine dioxide.

Controlling Microbiologic Growth in Open and Closed Systems

Despite regular treatments of various products to control microbiological growth, slime deposits can persist in troublesome ways in cooling systems. Typically, slime may be seen in a cooling tower’s louvers, sump basins or distribution decks, or other locations that are even more worrisome, such as distribution piping or the condensers’ tubes and/or tube sheets. When this condition occurs, frequent cleaning is necessary, or high corrosion rates can occur and damage the refrigeration equipment.

Slime bacteria excrete protective polysaccharide film, which traps solids in the water, which then form deposits that are hard to get rid of in cooling systems. These deposits are also acidic: they corrode underlying metal surfaces. Slime also shields live bacteria from a number of microbiocides, so that they continue to grow in the water. It’s a tough situation to correct.

What’s more, slime deposits have insulating properties that not only reduce heat transfer but restrict water flow, reducing the effectiveness of the refrigeration process, and driving up operating costs.

Even more alarming is that studies show slime deposits pose health concerns, in that they can promote environments in cooling systems conducive to Legionella pneumophila, which leads to infection with Legionnaires Disease, a serious health issue.

The Verox-8 Advantage

Chlorine dioxide works by penetrating biofilm deposits and destroying the bacterial cells that secrete slime. Furthermore, chlorine dioxide is a selective oxidizer. It won’t degrade phosphanates, azoles or polymers crucial to water treatment; nor will it promote corrosion of steel or copper components.

Jamestown Technologies has used Verox-8 with good results in several projects where water treatment cooling systems had been compromised by microbiologic deposits, and where corrosion was also occurring. Verox-8 is Environmental Protection Agency-registered. As a single-drum microbiocide, it does not require complex activation equipment, nor do hazardous precursor chemicals need to be stored for its use. While traditional chlorine dioxide technology has been recognized as effective, it’s also been known to require significant maintenance and capital expenses, as well as heightened attention to plant safety and handling. Verox-8 provides the benefits of traditional chlorine dioxide technology, but not the problems.

In addition to performing well when there is persistent slime or biofilm, Verox-8 also is effective when systems have elevated pH levels or there is nitrogen or ammonia contamination, or when there is contamination from mineral or vegetable oils, as well as organic compounds that promote microbial growth.

Wastewater Treatment Process – Environment friendly Effluent Disposal

The main objective of wastewater treatment is to ensure safe and eco-friendly disposal of industrial effluents. Wastewater can be generally classified as a mixture of domestic sewage, industrial wastewater and surface water which makes its way into the sewers. The wastewater treatment process greatly depends on the standards set for the effluent quality before the water is allowed to merge with the rivers or used for agricultural irrigation.

There are several methods and wastewater treatment procedures which largely includes a combination of physical, chemical and biological methods to achieve best results. Broadly classified under six different methods, wastewater treatment process removes organic matter, suspended solids and nutrients from wastewater.

Preliminary Treatment

This is the first stage of the wastewater treatment process which uses a screen to remove solid inorganic materials. The screens consisting of upright bars remove large pieces of trash like plastic, paper, soft drink cans etc. The raw sewage which is known as influent is cleaned off large objects, thereby protecting the pump and other moving parts. The offensive materials is then disposed off at landfills.

Primary Treatment

Using the process of sedimentation along with certain chemicals, the colloidal solids are removed from the wastewater. The primary sludge which is pushed towards the center is pumped away for further treatment, while the wastewater is moved for secondary treatment.

Secondary Treatment

The wastewater is next passed into large rectangular tanks which includes use of micro-organisms which breaks down suspended organic solids. Otherwise known as the activated sludge process, this step includes use of aeration tanks where microbes consume organic waste. High concentration of organic material in the wastewater is treated using activated sludge, trickling filters and Rotating biological contactors. The treated wastewater makes it way to the tertiary phase of wastewater treatment.

Tertiary treatment

Use of disinfectants to reduce pathogens is a critical step in wastewater treatment which involves the use of chlorine. Depending on the influent, every wastewater treatment plan has different operations before it can pump the treated water back into the river.

Sludge treatment

The sludge treatment can be done by either thermal destruction, gas to grid or anaerobic digestion. Each of these steps are aimed at treating the sludge and putting it to good use. The gas produced during the anaerobic process contains methane which is used to generate electricity. The residual liquid is pumped back to the aeration tanks for further treatment.

Effluent discharge

The last process in the wastewater treatment procedure includes the release of treated water back into the river or stream. Bio-monitoring is an extremely critical step which determines whether the treated water has an adverse impact on flora and fauna.

Reduce Carbon Footprint with Solid Water Treatment

Much has been said about reducing the carbon footprint globally, and controversy still exists over the percentage of human contribution to the undeniable rise in carbon dioxide levels in the atmosphere. What is certain is that carbon dioxide levels in the atmosphere have risen dramatically since the dawn of the Industrial Revolution, by at least 115 parts per million. Lest anyone doubt the danger inherent in the infamous ‘greenhouse effect’, a perfect example of the runaway results can be observed in Earth’s sister planet, Venus. This planet, which once had an atmosphere similar to Earth’s, now is roasted by a surface temperature roughly 450 degrees Centigrade higher than Earth’s, due almost entirely to the greenhouse effect which rules that planet.

What can be done to reduce carbon footprint?

Clearly steps must be taken to reduce the levels of carbon dioxide which are emitted into the atmosphere, and that equates to reducing carbon footprint. To be sure, individuals must do their part in lowering the amount of carbon dioxide each person puts into the air, but corporations and businesses have a major responsibility as well. One of the major ways this can be accomplished is through the use of solid water treatment and industrial water treatment companies which make that their business.

Water treatment in cooling towers, boilers, and closed-loop systems is necessary because of the potential for corrosion, scale buildup, and the deposits of materials in suspense in the circulating water. In the past, this kind of water treatment was typically done with chemicals that were trucked to the cooling tower sites in large barrels or drums. However, this approach is one that adds significantly to the carbon footprint of a treatment operation, and when multiplied by the number of cooling towers around the country, the footprint soars unbelievably.

For instance, the chemicals themselves must be shipped from the location where they are produced to various cooling towers for use, and this involves the usage of trucks which belch carbon dioxide into the atmosphere. Since solid water treatment materials can be packaged in much smaller containers, the shipping is significantly less, and the use of plastic barrels would be unnecessary. This represents a double savings in carbon dioxide production, since the packaging and trucking would be greatly reduced.

What other alternatives exist?

There are other alternatives for preventing the problems associated with cooling towers beside solid water treatment however. Green results can be attained by the use of sophisticated filtration systems, water softeners, carbon block filters, oxygen dissolution, reverse osmosis, and even ultraviolet treatments, although these are sometimes insufficient to manage the problems.

The appeals of a solid water treatment system are many, beginning with the fact that several of the most effective proven chemicals are mixed into a concentrate before shipping, and when transported to the treatment site, can be applied directly from the container. All the drawbacks of liquid chemicals are neatly bypassed and eliminated, because there are never any spills, on-site storage is unnecessary, no pails of chemicals are ever handled, and there are no disposal problems with containers.

In effect, this solid water treatment strategy provides all the benefits of a chemical treatment program without any of the hassle or danger inherent in the handling of chemicals. Depending on the volume of water being treated at a given facility, this kind of approach has the potential of reducing the carbon footprint by literally thousands of pounds each year, and when multiplied by the number of cooling towers that require treatment, the reduction could very well be massive. This is clearly a solution worthy of consideration.

Waste Water Treatment in Hospitals and Medical Facilities: Myths and Facts

The average hospital has 160 beds, most of which are in use all of the time. This presents a great deal of opportunities for the creation of waste water in multiple ways. In L.A. county, CA, for example, there is an average of 319 gpd of waste water produced per bed on a daily basis. As a result, there have been many myths about waste water treatment that distort the way one approaches water treatment within a hospital. This article will subvert a few of these myths by taking a look at the truth behind them.

Myth: The quality of hospital waste water doesn’t really matter, because the sewage waste water treatment system will filter out any contaminants.

Fact:According to the United States Geological Survey, only 60 percent of all suspended solids are removed from waste water by primary treatment. Since four out of every ten suspended solids in waste water continue on untreated, higher amounts of contaminants in hospital waste water will have significant impacts that the sewage waste water treatment system cannot prevent.

Myth: The only major concern for hospital waste water is microbial

Fact: Although microbial contaminants are easy considerations for contamination in hospital waste water, the problem does not stop there. There are many other harmful contaminants in hospital waste water that need to be accounted for. For example, mercury and other dangerous heavy metals are often suffused throughout hospital waste water on a daily basis; inorganic contaminants like these often end up in river sediment, significantly harming the life ecology therein.

Myth: Hospital waste water isn’t that much worse than the waste water generated by individual people.

Fact: Hospital waste water is exposed to a high concentration of antibiotics, medicines, hazardous microbes. These contaminants come from patient treatment solutions, as well as medical research the utilizes materials and chemicals not as common to most other sources of water waste. In fact, hospitals are the only sources of pathogens such as iodinated X-ray contrast media. This means that a hospital with untreated waste water is a much larger contributor of contaminants than most other sources.

Myth: Water supplied by the utility companies is good enough for all applications within a hospital.

Fact:A variety of contaminants, including heavy metals are present in all tap water. In the United States, for example, 42 out of 50 states have tap water that is contaminated by 141 unregulated contaminants that the U.S. Environmental Protection Agency has not even established any safety records for. The only way for a hospital to get rid of them is with effective water treatment systems that target incoming water. In other words, much of the waste water used by hospitals is already contaminated before it is even used.

Myth: The contaminants in hospital waste water can be eliminated through the use of normal waste water treatment methods.

Fact:Many of the contaminants in hospital waste water are either resistant or completely immune to normal waste water treatment procedures. This means that even if a hospital takes steps beyond simply allowing the sewage treatment system to do its job, they can be completely ineffective if the right tools are not used for their unique conditions.

What can hospitals do to mitigate the effects of waste water that they generate?

The key for hospitals seeking to mitigate the effects of their waste water is an investment in green water treatment solutions. This includes water recycling, filtration and other waste water treatment systems that can both reduce the volume of hospital waste water contributed to the sewage system and mitigate the amount of contaminants contained therein.

Jamestown Technologies May 2014 Blog Post Recycling waste water for drinking Are you ready for it

Recycling waste water for drinking: Are you ready for it?

With the projected growth in world population, and the ever-rising demand for clean water, the demand for recycling waste water is gradually on the rise. While water on earth is already recycled in the sense that it goes through the planetary water cycle, the phrase ‘water recycling’ is usually used to characterize the process through which, waste water from homes and businesses is sent over a pipeline system to treatment facilities, where the water is then treated to remove solids and certain impurities. The level of this treatment is commensurate to the intended use of the water. The water is then routed to a recycled water system for appropriate use.

For several years, recycled waste water has primarily been used in irrigation, with the goal of sustainability and water conservation. In most locations, recycled water was not directly used for drinking purposes. However, it should be emphasized here that using recycled water for other uses still did help conserve fresh water for drinking, thus allowing for a more sustainable approach to water consumption.

At present, projects for recycling waste water are being undertaken all over the world, with Israel being the world leader, recycling 80% of their waste water for reuse in irrigation projects. In recent years, a lot of other locations such as the Orange County Water District in California, and some locations in Singapore, are subjecting waste water to more advanced treatments with the intent of the final product being used for drinking. Orange County in particular is a major success story, with a production of 100 million gallons per day serving 850,000 people. The recycled waste water is being mixed with the groundwater supply and reaches over 70% of the residents. Water thus produced has also managed to meet and exceed all state and federal drinking water standards. It is worth mentioning here that these standards have actually been revised to be stricter, due to the novelty of the underlying technology and process. The World Water Council has long ago declared that the quality of this recycled water is just as good, if not better, than the tap water in any city in the developed world.

The United Nation warns that by 2030, half of the world population will face water scarcity, accelerated by climate change and population growth. This could spark off a shortage in food production, along with a health crisis due to increased exposure to polluted water. Unfortunately, introducing recycled waste water for drinking purposes has not been tried as a serious possibility until very recently. Even Orange County began their contribution to the drinking supply as late as 2008, whereas their recycling system has been operational since the 1970s. Nevertheless, operators associated with such projects feel confident that the system is now well-established and ready for deployment on a much larger scale. There is also consensus that as the shortages become more extreme, there will be an increased awareness of the need for finding alternative resources.

How Cooling Water Treatment Can Reduce Cost in a Thermal Power Plant

Besides being a necessary resource to sustain life on earth, water, as we all know, is an excellent coolant. Not only is it abundantly available, but it is also less expensive. Compared to other substances, water can be handled easily without causing harm to anyone around it. Water is also known to carry larger amounts of heat per unit, even more than what the air can carry. It’s a flexible element that doesn’t expand or compress regardless of the temperature within which it is kept and furthermore, water, unlike other elements, does not decay. This is why water treatment companies use water as their primary element in water treatment processes.

Why Cooling Water Treatments Are Recommended To Industrialists

For thermal power plants, cooling water treatments are extremely necessary, without which these plants cannot operate at higher efficiency. The steam that is generated from the electric generation turbine must be cooled properly to minimize turbine pressure. For proper and efficient machinery operation, water is required to cool the systems, otherwise most industrial production operations may exhaust due to heated machines. For optimum efficiency, most industries such as refineries, mills, chemical, food, processing and manufacturing plants, along with large industrial buildings require proper cooling water treatments. Water treatment companies provide this service as a way to control the temperature and pressures in a given site of operation by diverting the heat produced from constant machine usage in the cooling water, thereby reducing the heat to a non-threatening level.

Once the water treatment process is complete, the water must be cooled off before use or fresh water should be used. The aim is to ensure that the machinery used for various productions, industrial or manufacturing processes remain in a healthy state without overheating. It is equally important to note that before selecting water treatment companies, you must monitor that the cooling water treatment they provide is effective and efficient. You will need to select the right company for your needs because cooling water treatments depend on the type of process that needs to be cooled along with its characteristics and location.

The Importance of Monitoring Cooling Water Treatments

In order for the cooling water techniques to be carried out efficiently, diligent and constant monitoring is required. Effective monitoring of corrosion, deposition and microbial growth will help you determine the effectiveness of the process and will also help you identify best cooling water treatment levels to help reduce costs when it comes to energy, water and chemical usage.

How Cooling Water Treatments Affect Cost of Operation

Production, manufacturing and industrial plants require large amounts of energy to carry out their processes. Large amounts of energy produce larger amounts of heat that can hinder the performance of the processes, leading to low efficiency and increased costs in maintaining and/or repairing the damages. If heat is uncontrolled, the processes suffer and costs such as excess water, waste water and increased energy, increase even more.
