No. 85 Algaecide, is a polymeric, cationic biocide that has been developed for controlling the growth of algae, bacteria, and fungi in recirculating water systems such as cooling towers, evaporative condensers, closed cooling water systems and industrial air-washing systems.

Algae are microscopic plants that grow rapidly in cooling towers, spray ponds and other recirculating systems exposed to sunlight. These free-floating growths can be carried to the condenser or heat exchanger by the condenser or heat exchanger by the recirculating water where they lodge and act as binders for sludge and suspended matter. In addition, algae can contribute to the formation of slime deposits by providing organic matter necessary for the growth of bacteria. These biological growths restrict water flow, reduce heat transfer efficiency and increase head pressures, all of which result in lower efficiency and increased power and service costs. Treatment of recirculation water with No. 85 Algaecide prevents growths of algae and bacteria from developing to the point where they cause the problems described.
