In a closed system, water circulates in a closed cycle and is subjected to alternate cooling and heating without air contact. Heat, absorbed by the water in the close system, is normally transferred by a water-to-water exchanger to the respondent-circulating water of an open respondent-circulating system, from which the heat is lost to atmosphere in this paper a detailed analysis is made to the closed cooling water system at power plant. The water quality indexes like PH, TDS, Conductivity and Iron pick up were used to evaluate the operational condition of cooling water systems. The paper analyzes various chemical treatment adopted to control corrosion rate and scaling synergetic effect of various combination are evaluated. Factors involved in this aspect are the water chemistry, system characteristics, environmental limitations, personal preferences and cost in adopting and implementation of operation of plant. This paper also demonstrates that the recovery and reuse of cooling water aspects like water make up monthly average besides corrosion rate reduction.
