Feasibility Study For Make-Up Water Quality For Cooling Tower By Electro-Coacgulation Process, Sasipim Manasilp, Cattaleeya Pattamaprom

Applied Environmental Research

Cooling tower was a type of heat transfer equipment which was used to enhance heat rejection to the environment by increasing the surface contact between water and air. Water used in the cooling tower system had to be pretreated to prevent scaling and corrosion. As most factories in the northern part of Bangkok utilized both tap water and groundwater, which was known to contain large amount of minerals and suspended solids, water pretreatment was crucial before entering cooling towers or the heat-exchanging systems. Typical water pretreatment system consisted of sand filtration, carbon adsorption and ion-exchange resin adsorption to remove particles …
