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.

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.

Use Oxygen Scavengers for Boiler Water Treatment

Use Oxygen Scavengers for Boiler Water Treatment

There are many different types of boiler water treatment programs used today around the world to help aid with commercial, industrial and institutional facilities. Oxygen scavenger boiler water treatment schedules can be an essential part of your regular maintenance program to ensure effectiveness and extend the life of your equipment. Without necessary maintenance, your equipment will not run efficiently or last a lengthy amount of time, hindering your business. Large industrial equipment such as boilers and steam equipment should be taken care of as an asset and treated with products such as water treatment chemicals on a regular basis.

Boiler water treatment is just one of the ways that is designed specifically for boilers, steam and condensate lines as well as a variety of equipment used in numerous buildings and industrial facilities today. Using this style program will help with buildup of boiler corrosion and control the deposits that can form in this type of equipment from everyday use. Boiler corrosion is a big problem for equipment that does not have a regular maintenance program in place or an effective boiler water treatment program.
Oxygen scavenger boiler water treatment programs are essential for any company that utilize boilers or steam equipment for their everyday operations. Without some form of boiler water treatment you risk significant corrosion and buildup in your equipment. There are many different types of oxygen scavengers out in the market today that can handle any number of situations. Using the correct type of oxygen scavengers and water treatment chemicals are important to reduce buildup and increase efficiency.

Water treatment chemicals can help significantly with boiler corrosion buildup as well as extending the life of the equipment by ensuring that it runs more effectively. Having an abundance of oxygen in feed water can cause a problem, so often a deaerator is used to remove a large amount. While this can help greatly, a small amount of oxygen remaining can still cause corrosion buildup issues. For this, oxygen scavengers are added to the water, which can be also mixed with other chemicals to increase its effectiveness. These oxygen scavengers can vary from type to type, depending on your need, including volatile oxygen scavengers.

Volatile oxygen scavengers is another type of oxygen scavenger boiler water treatment that are easily evaporated at normal temperature and successful for removing oxygen from feed water tanks, boilers and other steam equipment to avoid boiler corrosion. Some volatile oxygen scavengers can be partnered with other oxygen scavenger chemicals to improve their effectiveness. It will depend on the type and style of boiler or steam equipment you have and its purpose as to what types of water treatment chemicals you will require for your regular maintenance.

The use of oxygen scavengers and water treatment chemicals in facilities such as factories, commercial buildings and other industrial areas will ensure that your boiler or steam equipment will run efficiently and effectively for a longer duration. Protecting your investment is an important part of business and boiler water treatment programs and oxygen scavengers are important aspects of these treatment programs.
