Comprehensive Cooling Tower Treatment
EST
UNESCAP, Thailand
Background:
UNESCAP cooling towers were operated for a year using chemical dosing as the primary treatment. The chillers approach water temperature was found to be 8°C, indicating significant loss of efficiency generally attributed to fouling and scaling.

Project Results:
Background:
The cooling towers are operating eciently and without scaling, corrosion
or bio-fouling.
Maintenance:
Maintenance is significantly reduced
Energy savings:
Chillers approach water temperature dropped from 8°C to 2.1°C, increasing
the chillers efficiency by 9%
Water savings:
Before EST: 42m3 blowdown/day
After EST 15m3 blowdown/day
65% water savings
Chemical savings:
100% of the chemicals were eliminated
