Understanding the Chemicals Used in Cooling Tower Water Treatment

Cooling towers work by using heat exchange. Water is constantly circulated through the system, and, when it enters the cooling tower heated due to industrial processes, it is exposed to the air, resulting in evaporation. This reduces the temperature of the water enough that it can be recirculated and used for cooling. Of course, this cycle of evaporation requires the supply of water to be continuously replenished. However, the water that is fed into the cooling system is typically rife with contaminants, which can cause scale and corrosion. The chemicals that water treatment companies use are designed to address and prevent these issues.

Cooling towers require proper maintenance to ensure the most efficient operation and to reduce downtime. There are several cooling tower challenges: water conservation, corrosion, scale, deposits, and microbiological activity. Evaporated water leaves behind dissolved impurities from the makeup water which can become concentrated leading to scale, deposits, and corrosion. These issues can cause water equipment failure leading to production downtime, added costs, and reduced efficiency. Professional water treatment minimizes these challenges by expert support, focused optimization, and industry Best Practices.
