Various Types Scales formation in Cooling Tower Water Treatment

The different kind of scales that occur in cooling tower water treatment system are,

1. Calcium carbonate Scale:

Results primarily from localized heating of water containing calcium bicarbonate. Calcium carbonate scale formation can be controlled by pH adjustment.

2. Calcium sulfate scale:

Usually form as gypsum is more than 100 times as soluble as calcium at normal cooling water temperature. It can be usually be avoided by appropriate blow down rates.

3. Calcium and Magnesium Silicate scale: 

Both can form in cooling water system. This scale formation can normally be avoided by limiting calcium, magnesium and silica concentrations through chemical treatment or blow down.
