The Neutralizing of M-alkalinity of Cooling Tower Water by Air Pollutants

Abstract

Applying actual cooling tower water analyses together with air pollution and meteorological records to the theoretical equation calculating M-alkalinity of cooling tower water which is formulated in consideration of air pollution, capture efficiencies of typical air-conditioning cooling tower for each air pollutant have been estimated approximately as 25% for SO₂, 30% for NO₂, and 40% for NO. Using the equation, the method to establish adequate cycles of concentration of a cooling tower water is explained.
