14-10: Efficient Polymer Use in Cooling Tower Makeup Water Treatment at Coal Oxidizing Biocides

14-10: Efficient Polymer Use in Cooling Tower Makeup Water Treatment at Coal Oxidizing BiocidesThe Sunflower Electric Power Corporation operates a 349 MW coal fired power plant with a zero liquid discharge policy. As part of the cooling tower makeup water treatment, a polymer is used along with ferric sulfate in the lime soda ash softening process in a reactor type clarifier. Understanding fluid dynamics and polymer chemistry is critical in designing effective mixing equipment to maximize the value of high molecular weight polymer. The high
