ROOFTOP AND PROCESS WATER APPLICATIONS

We offer you a choice in chemical free technologies for bacteria and scale control in many commercial and industrial applications. Cooling towers, evaporative coolers, heat exchangers, chillers, process recirculation systems, wastewater and complete point-of-entry treatment systems. Multiple manufacturers are used to properly configure systems and technical personnel are available for timely estimates. A programmable system is normally capable of driving the accessories for TOTAL TREATMENT.

Why consider an alternative to traditional
chemical water treatment in your industrial applications?

• Save the money you now spend on water treatment chemicals and the associated costs of insurance, storage, handling and disposal
   
• Make EPA & OSHA compliance easier, or unnecessary by eliminating dangerous chemicals
   
• Eliminate discharge of toxic chemicals and related environmental liabilities
   
• Reduce your costs by reducing the frequency and amount of additions and discharges in open systems
   
• Treat water when there are concerns that chemicals are too costly or the application itself prohibits their use 
   
• Descale systems that have lost efficient heat transfer without the need for rodding or acid cleaning
   
• Eliminate algae and bacteria, including difficult problems such as yeast and Legionella, without having to know the properties or even the identities of the problem organisms

• No chemical or biological education is required
   
• Because it is the right thing to do.
   

  Chemical, Scale and Corrosion Control

  A Non-Salt, Non-Chemical, World-Class viral and microbial kill is maintained in the tower.

  Scale and Corrosion Control is achieved with the addition of ionization and oxygen electrodes.

  Our Technology manages the stability and solubility of calcium, magnesium, bicarbonates, carbonates and silicates which are directly responsible for scale, deposit and corrosion problems in cooling towers.

  Ionization produces strong coagulation and flocculation throughout the tower. Coagulation and proper filtration control colloidal organics, silt, dirt and insoluble metals, preventing galvanic corrosion, reducing maintenance and saving unnecessary down time.

   

  With ozone and ionization gaining acceptance in cooling tower water treatment, ionic copper and natural oxygen systems provide the best available technologies for cooling tower management. Oxygen radicals (OH and O₁) from the water itself provide more powerful, less corrosive oxidizers than ozone and are enhanced by the residual sanitizer, ionic copper. The oxygen and residual ionic copper act as a powerful biocide that greatly decreases or nearly eliminates the need to remove large quantities of water from the cooling tower in order to decrease the concentration of organic and mineral solids in the system.

  Ionic copper and natural oxygen treatment reduces the need for chemical additives to the cooling tower water. In a properly installed and maintained system, bacterial counts are reduced, with a subsequent minimization of the build-up of biofilm on heat exchanger surfaces. The resulting reduction in energy use, increased cooling tower operating efficiency and reduced maintenance effort provide cost savings as well as environmental benefit and regulatory compliance with respect to discharge of wastewater. Cooling towers associated with chillers for air-conditioning should immediately consider the purchase of a Cooling Tower System.

   A cooling tower functions to cool a circulating stream of water. The tower acts as a heat exchanger by driving ambient air through falling water, causing some of the warmed water to evaporate, which cools the water, and then circulates this cooler water back through the equipment that needs cooling (such as a chiller condenser). Typically, chemicals such as chlorine and chelating agents are added to cooling tower water to control biological growth (called "biofilm") and inhibit mineral build-up (called "scale"). The control of biofilm and scale is essential in maintaining cooling tower heat transfer efficiency. As the water volume in the tower is reduced through evaporation and drift, the concentration of these chemicals and their byproducts increases. Cooling towers also pick up contaminants from the ambient air. To maintain chemical and contaminant concentrations at a prudent level, water is periodically removed from the system through a process called "blowdown" or "bleed off."

  The blowdown water and the water lost through evaporation and drift are replaced with fresh "make-up" water (which also contains minerals and other impurities). Blowdown water must subsequently be discharged to a local wastewater treatment facility or discharged onsite to the environment. The blowdown water typically contains little organic material, and the local wastewater treatment facility will charge extra sewage fees for accepting the water. These costs can be quite significant in the overall costs of operating a cooling tower. Discharge of the blowdown water to the environment onsite is coming under increasing regulation because of the contaminants typically found in blowdown water. Oxygen will dissipate quickly and not be found in the blowdown water. This reduces the overall chemical load found in the discharge water, making it much easier to comply with regulations.

   

   Field tests have demonstrated that the use of oxygen and ionization in place of chemical treatment can reduce the need for blowdown, and, in some cases where make-up water and ambient air are relatively clean, can eliminate it. As a result, cost savings accrue from decreased chemical and water use requirements as well as from a reduction of wastewater volume. There are also environmental benefits as fewer chlorine or chlorinated compounds and other chemicals are discharged. An Oxygen/Copper System requires less maintenance per year than either a chemical or chemical/ozone system.

  There is no doubt that ionization combined with oxygen acts as a de-scaling agent. The reason is that oxygen with ionization breaks down the biofilm that serves as the binding agent that causes scale to adhere to heat exchange surfaces. When scale build-up on condenser tubes is reduced, higher heat transfer rates are achieved. Increasing the condenser heat transfer rate reduces the chiller head pressure, which then allows the chiller to operate more efficiently and use less energy. Calcium and magnesium carbonate revert and maintain to a bicarbonate state up to 150°, staying in solution.
