Cooling Tower Water Treatment

Without effective water treatment, a cooling water system can suffer from scale formation, suspended solid deposition, corrosion and fouling problem. This reduces efficiency, shortens plant life and makes operation unreliable and unsafe.

1] Scale Prevention

Scale or lime-scale is a hard, rock-like deposit of calcium or magnesium salts that forms in heat exchangers and cooling tower packing as a result of heat and increased concentration factor. Scale formation impairs heat transfer, interferes with flow and cooling, and can be a breeding ground for legionella bacteria.

Cooling water scale control can be achieved by using SHUBHAMs Water Softener or Reverse Osmosis Plants.

2] Accumulation of Suspended Solid & atmospheric dust & dirt

Cooling towers act as giant air washers. Finely misted water is sprayed into a column of moving air. In cooling towers this mist increases the surface area of the water so heat transfer from water to air is more efficient and effective. In air washers this mist traps particulate matter out of the air and “washes” it into a sump for disposal.

Unintended and undesirable though it may be, cooling towers accumulate large quantities of dirt, dust, and other airborne solids. They become suspended solids in cooling water coursing through cooling towers, pumps, chillers, condensers, heat exchangers, etc. As dirt and suspended solids accumulate in cooling water and cooling equipment, there are a number of undesirable results.
Accumulation of Suspend solids, dust & dirt can be controlled by using SHUBHAMs Side Stream Filter.
