Cooling Water Bio Control
We offer a complete line of oxidizing and non-oxidizing biocides, algaecides and biodispersants that are effective in many different cooling water applications, including open recirculating cooling towers, once-through cooling systems, closed loop cooling systems, air washers, cooling ponds, thermal energy storage tanks, and pasteurizers.
Our STA-BR-EX®, ControlBrom®, ACTIBROM®, products can effectively reduce the amount of oxidizing biocide required to control microbiological activity in cooling water. Our Bioreporter™ products, when used with a 3D TRASAR technology controller, detect changes in microbiological activity and adjust the biocide feedrate for tighter control and less overfeed.
For control of Macrofouling by zebra mussels and other mollusks, we offer effective molluscicide treatments that can be used in fresh and potable water systems. Your sales engineer can help choose the right treatment program for your system.
Environmental Hygiene Services provides specialized services to help control private and public health risks due to pathogens such as Legionella. They conduct detailed risk assessments and offer ongoing management programs customized for your specific environment.
