Cooling Tower Water Treatment: Enhancing Efficiency, Reducing Scale, and Extending Equipment Life

Cooling tower water treatment is critical to keeping your industrial cooling systems operating efficiently, reliably, and with a long service life. Cooling towers remove unwanted heat from manufacturing processes, power plants, HVAC systems, and commercial buildings all across the country. When left untreated, cooling water can cause scale buildup, corrosion, biological contamination and fouling which can decrease your system's ability to transfer heat and drive up operating costs.

With a proper cooling tower water treatment program in place, you can maximize performance and efficiency, minimize maintenance and downtime, save water, and prolong the life of your equipment.

Why Cooling Tower Water Treatment Is Important

Water evaporates from cooling towers constantly while they’re operating. This evaporation leaves behind dissolved solids that become more concentrated over time. Water chemistry that’s too extreme can cause problems within your system.

If cooling water isn’t treated properly it can cause:

Scale Buildup

Deposit formation from minerals like calcium and magnesium can coat your heat transfer surfaces. Scale inhibits heat transfer making your system work harder and use more energy.

Corrosion

Damaging metal surfaces causes leaks and equipment breakdown. Repairing damage from corrosion can be extremely expensive.

Microbial Growth

Heat and stagnant water allow bacteria, algae and other microorganisms to grow and flourish. This bio growth can cause fouling and clog pipes.

Fouling and Sedimentation

Silts and suspended solids can build up anywhere in your system. These particles reduce water flow and affect your ability to properly transfer heat.

Common Cooling Tower Water Treatment Methods

Chemical Water Treatment

Chemical treatment continues to be the most effective way to control scale, corrosion and biological growth.

Advantages include:

a proven technology

flexible application

can be used on all water types

easy retrofit

Physical Water Treatment

Physical treatment methods control scale buildup with little or no chemicals.

Includes:

electronic water descalers

magnetic water treatment

electrolytic water conditioners

Filter Treatment

Filters work to constantly remove solids and suspended matter from the water, leaving the entire system cleaner.

Applications of Cooling Tower Water Treatment

Power Generation Plants

Cooling Towers keep power stations from overheating so they can generate more power.

Manufacturing Facilities

Cooling towers are commonly found at these manufacturers:

Chemical plants

Steel mills

Food processing facilities

Pharmaceutical companies

Plastic manufacturers

Commercial HVAC Systems

Cooling towers support heating, ventilation and air conditioning systems for skyscrapers, hospitals, shopping malls and office buildings.

Data Centers

Cooling towers effectively cool server rooms and other IT equipment.
