Ei Cooling Tower Blowdown Initiative Water Must Be Treated to Prevent Scale, Corrosion & Bio-fouling

Ei Cooling Tower Blowdown Initiative Traditional Chemical Treatment

Ei Cooling Tower Blowdown Initiative Typical Chemicals Used

Ei Cooling Tower Blowdown Initiative Traditional Chemical Treatment Wastes Water As the water evaporates, the chemicals are left behind. To keep the chemicals in effective balance, water must be drained and more water brought in. This “blowdown” can be 10 to 35 percent of water consumed. Water and sewer costs for this “blowdown” can be significant!

Ei Cooling Tower Blowdown Initiative Dan Duke, founder of WCTI, discovered in 2000 if you use a super softener to remove the hardness(calcium and magnesium) down to a gnat’s hair, Mother Nature will give you corrosion and bio-fouling protection, for free!

Ei Cooling Tower Blowdown Initiative WCTI Methodology 1. High Efficiency Softener (HES) uses sodium (Na) zeolite resin to eliminate the hardness(Ca and Mg) in the tower supply water. 2. Resin absorbs Ca and Mg and exchanges with Na for a one-to-one exchange. Naturally occurring pH climbs to 9.3 10.0 and along with the high TDS(total dissolved solids) prevents biological growth. 3. Silica is naturally polymerized with the increased pH and high TDS in the absence of hardness. 4. The resulting NaSiO2, sodium silicate, is considered an excellent corrosion inhibitor and is naturally formed under WCTI conditions. RESULTS: NO scale and effective control of corrosion and biological growth – eliminates the need for chemical additives and blowdown
