Cooling towers used for water heat rejection after the industrial process, over the years showed that is a convenient place for bacteria and pathogens to multiply. The warm, humid environment, constant aerosol, air, and water intake from outside all contribute to the formation and build-up of bacteria and viruses. Especially if the air around the cooling tower is dusty or humid. Using chemicals somewhat helped to address the issue, but soon proved too detrimental as it resulted in high levels of corrosion, resilience over time, and many by-product formations.
This further pushes this issue as biological water and air intake mix with the chemicals, leading to a never-ending circle of additional chemicals to eliminate the by-product of the previously used ones. Since the cooling of water is achieved through water evaporation, the dissolved solids concentration in the cooled water will significantly increase, calling for necessary disinfection. UV and AOP disinfection methods are the most optimal solutions available for this treatment. That is because it does not involve chemicals, does not create resistance or form corrosive by-products.
UV systems are also the most cost-efficient solution available for cooling tower water due to the complexity of the operational environment. It is also effective against all known bacteria and viruses. Lastly, UV offers operation advantages since it is not labor-intensive and has a relatively small footprint.
ULTRAAQUA UV standard disinfection and AOP systems deliver this and more. Equipped with the ULTRAWIPER™ wiping system for quartz sleeve, it eliminates the need for wiping quartz sleeve manually. ULTRAAQUA UV AOP system would offer an additional advantage as oxidizing radicals would also eliminate the contamination across piping. Both UV systems could be installed at the buffer tank inlet point or inside it.Get in touch

UV light is effective against all known bacteria and viruses. Utilizing energy-efficient UV technology, ULTRAAQUA UV systems can eliminate all pathogens brought in by outside sources and the leftover build up after evaporation in the tower.
The use of a variety of chemicals that would mix with suspended solids and continuous air presents a challenge. Over time, the bacteria, and viruses begin to build resilience and the mixture of microorganisms makes it a perfect place for the formation of complex and unfamiliar by-products. Some of which are extremely corrosive for cooling towers. UV eliminates all bacteria and viruses without these hindrances.
AOP is known for its extremely effective performance by its oxidizing radicals that leads to providing the ultimately pure water. In addition to this, AOP treats cooling tower water would also carry radicals through the majority of the cooling system, greatly assisting with biofilm formation in piping and other treatment steps.
Standard UV disinfection offers the smallest footprint available compared to its substitutes, it’s also easiest to install and control, requiring very little maintenance, and has the lowest energy consumption. Even though more complex, ULTRAAQUA UV AOP solution offers unparalleled destruction of microorganisms found in the water and of the process water pathway – eliminating the need for additional treatment.
