What Is Cooling Tower Water Treatment?
Cooling tower water treatment is the combination of water pretreatment, chemical dosing, blowdown control, filtration and routine testing used to keep recirculating tower water from forming scale, corroding metal, fouling surfaces or growing harmful microorganisms. The aim is stable heat transfer, long equipment life and controlled water use.
The need comes from evaporation. A tower circulating 1,000 m³/h across a 5–6°C cooling range evaporates roughly 10 m³/h, about 1% of the flow. That vapour is nearly pure water. The salts stay in the basin, so the circulating water gets more concentrated every hour unless you bleed some off and replace it.
