Scale Prevention in Water Cooling Tower

Scale problem is most common in the cooling towers. Calcium carbonate in the cooling water is the main ingredient which forms scale. The maximum amount of calcium bicarbonate that remains in the water depends upon the temperature and the carbon dioxide content of the water. The rise in temperature or reducing the free carbon dioxide, results in the deposition of scale.

A few experts said, if sulfuric acid is added to convert calcium bicarbonate to calcium sulphate, the resultant concentration of the calcium sulphate should not be allowed to exceed 1200 ppm. Otherwise, sulpahte scale may form which is very dense and difficult to remove. 

One best way to get rid of scale problem and corrosion is to install scale ban in the cooling tower water basin. It is an innovate concept which requires no regeneration, no maintenance, no chemicals. Scale ban also ensures no pollution and are very much effective for variable water qualities.
