Abstract
Deposit control is the most critical aspect of cooling water treatment because it is directly related to very purpose for a cooling system heat removal. Any deposit present in heat transfer surfaces impairs heat removal and there for reduces the efficiency of entire system.
Cooling water deposits are of two types - scales and fouling. Scales are hard dense, crystalline deposits for-med by the precipitation of dissolved materials when their solubility have been exceeded due to change in conditions. Foulants form softer non crystalline deposits because suspended materials settle out or adhere to metal surfaces.
