The chemical treatment of a plant cooling water system is typically provided through a vendor who supplies both chemicals and service. The most common type of system in industrial plants is an open evaporative, recirculating  cooling water system (with a cooling tower performing the heat rejection) but closed loop systems and once through systems also require treatment.  The chemicals employed are generally proprietary and are specifically engineered to provide control of : Corrosion Mineral Scaling Debris Fouling Biological forms (algae, fungi, aerobic and anaerobic bacteria) The cost for chemical treatment and service is small compared to the cost of the equipment in a cooling system, on the order of a few percent. However, if plugging of a heat exchanger with mineral scale occurs, or a heat exchanger fails by pitting due to corrosion, the entire annual cost for the chemical treatment and service can be exceeded by a single incident in...
