Overview

Cooling towers require water treatment since they are important pieces of equipment for many enterprises today, allowing them to remove heat from their surroundings and freeze their buildings and processes. These specialised heat exchangers are used in water-cooling systems, which demand proper water treatment in order to keep costs low and cooling efficiency high.

You risk corrosion, scaling, and microbial accumulation if you don't treat your cooling tower water. If conditions worsen, these difficulties can limit factory output, generate unscheduled downtime, and necessitate costly equipment replacements. Everyone who utilises a cooling tower must treat their water as a result.

Water Issues and Inefficient Cooling

Cooling towers are prone to a variety of issues due to the fact that they use water to remove heat from your systems. These include:

1: Microbiological deposits 

2: Dirt and muck

3: Scale build-up

4: Corrosion

5: Foam

1: Mud/Grime and Microbiological Deposits

Microbiological deposits such as fungi and algae can build slimes on the key heat transmission surfaces of the cooling tower, resulting in severe cooling inefficiencies. These deposits can build up in cooling systems to the point where they restrict the free flow of water and air, weighting down cooling tower structural members and perhaps causing them to break.

2: Deposits of Scale

When the concentration of a dissolved substance exceeds its solubility in water, scaling can occur. This is particularly problematic for materials whose solubility decreases as the temperature rises. Any scale that forms will reduce the cooling efficiency of the tower by interfering with heat transfer.

3: Corrosion

Corrosion is a constant problem in every water-handling system that has metal in touch with it. Maintaining lower pH levels, which is a method of controlling scale, can also hasten corrosion.

4: Foam

Foam can form in some systems due to cascading water in the cooling tower, albeit it is not as common as other cooling tower concerns. This can cause foam to overrun the cooling tower sump or cause the fans to blow foam out of the tower's top. Foam also has a tendency to concentrate deposit-forming elements, resulting in increased system fouling.

How cooling tower water treatment works?

While specific water treatment procedures can vary depending on the application, most cooling tower water treatment will comprise one or more of the following:

• Taking care of makeup water

• Filtration

• Treatment with chemicals

• Filtration on the side of the stream

A: Makeup Water Treatment

Makeup water, which is used to replace the water that has evaporated or spilled from the cooling tower, is frequently treated before being supplied to your system. This may entail removing hardness or silica, as well as changing the pH levels of the water, depending on the quality of the source.

B: Filtration

You can eliminate suspended particles and some forms of organic debris that can contribute to scaling, corrosion, and foaming by running your cooling tower water through filtration equipment. This is usually done at the start of your water treatment because removing suspended solids upstream can assist prevent fouling of ion exchange resins and membranes later on.

C: Chemical Remediation

Chemically treating your water is necessary to bring the chemical qualities of the water back into equilibrium, making it less likely to cause problems. Chemical therapies that are commonly used include:

• Ion exchangers and water softeners

• Anti-corrosion and anti-scale agents

• Biocides and algaecides

• Anti-foaming substances

• pH balancers

You can not only mitigate any water-related concerns, but also maximise the other phases of your water treatment with a whole stack of high-quality chemicals.

D: Filtration on the Side Streams

Side-stream filtration systems can assist remove contaminants that may have entered your cooling tower from drift contamination or process leaks if you plan on recirculating your cooling tower water throughout your system. Side-stream filters remove suspended solids, organic deposits, and silt particles from cooling tower water in modest increments. This decreases the chance of fouling or biological growth, resulting in increased water and energy efficiency due to less water discharged and less scale formation on any heat transfer surfaces.
