WATER TREATMENT The purpose of a cooling tower is to remove the heat generated by an HVAC system (cooling of compressor refrigerant and heat generated by the compressor itself).

Cooling is accomplished through the latent heat of vaporization. For each pound gallons) of water that a cooling tower evaporates it removes about 1, practices call for constant attention to water losses, not just from cooling tower systems, but from all water systems in the facility.

Economic Issues Water system management for cooling towers requires investment in a regular, comprehensive maintenance program coupled with water treatment program technical.

The principal objective therefore of water treatment is to produce water that is fit for domestic use reliably and consistently from a raw water source at a cost that is reasonable to the consumers.

A water treatment plant employs many individual treatment processes (sometimes called unit processes and unit operations) that are. Cooling Tower Water Treatment Principles.

Make-Up Water – Water added to the system to replace water lost through evaporation, bleed of and windage. Recirculation – The rate at which water circulates in the cooling tower (in m 3 /hour litres/sec).

Bleed Off – Water deliberately bled from the system to prevent the cooling system water from becoming too concentrated.
