Cooling Water

Protect cooling water from damaging micro-organisms

Cooling Water Treatment

Water recirculating in cooling systems can become contaminated with bacteria, algae, fungi and protozoa that lead to the formation of biofilms – often referred to as slime. If untreated, slime may lead to operational inefficiencies, microbial induced corrosion (MIC) and can potentially host harmful micro-organisms. Our leading cooling water treatment technologies control fouling and maintain system integrity.

Our cooling water treatment technologies inhibit microbial growth under a wide range of operating conditions found in typical systems, such as temperature, pH, sunlight, aeration and nutrient level in makeup water.
