Soft and hard water conditions need multi-functional treatment chemicals which usually come in a variety of specialist cooling water treatment products. For an open recirculating cooling water system we usually use 100% organic deposit, liquid scale and corrosion inhibitor. These products are also used for air washer systems and evaporative condensers. Due to moist environment bacteria, algae and Fungi are often found in industrial air washing systems, recirculating water systems and closed systems. For this reason a polymeric micro biocide has been created for controlling and eliminating these infections and reducing the problem effectively and safely.
