Cooling Tower Water Treatment System

A cooling tower water treatment system is an arrangement of technologies that remove damaging impurities from your cooling tower feed water, circulation water, and/or blowdown. The specific configuration of your system will depend on several things, including:

• What type of cooling tower you have (open circulating, once-through, or closed loop)
• quality of your feed water
• manufacture-recommended quality requirements for the cooling tower and equipment
• chemistry/makeup of your circulatory water
• regulatory requirements for discharge
• whether or not blowdown will be treated for reuse in the cooling tower
• type of heat exchanger
• cycle of concentration

A basic cooling tower water treatment system typically includes some type of:

• clarification
• filtration and/or ultrafiltration
• ion exchange/softening
• chemical feed
• automated monitoring

Depending on the impurities present in your water, any combination of these treatments might best suit your facility and make up your treatment system, so it’s important to consult with your water treatment specialist to ensure the right system for your specific tower is being considered. Depending on the needs of your cooling tower and process, these standard components are usually adequate. However, if your tower requires a system that provides a bit more customization, there might be some features or technologies you will need to add on.
