Overview

Cooling tower water treatment is crucial. Cooling towers are essential pieces of equipment for many businesses nowadays, allowing them to extract heat from their environs in order to cool their buildings and processes. These sophisticated heat exchangers operate on water-cooling principles. As a result, they require efficient water treatment to keep prices low and cooling efficiencies high.

Why is Cooling water treatment performed?

To reduce the risk of corrosion, scaling, and microbial growth in your cooling tower system, proper water treatment is essential. If circumstances deteriorate, these issues can impair factory output, generate unscheduled downtime, and necessitate costly equipment replacements. As a result, everybody who utilizes a cooling tower must treat their water.

What is normally controlled by a cooling tower water treatment system?

A cooling tower water treatment system may include the technologies required to regulate the amount of:

1: Alkalinity: It determines the possibility of calcium carbonate scale;

2: Chlorides: It can be corrosive to metals. Varying quantities will be tolerated depending on cooling tower and equipment materials;

3: Hardness: It promotes to scale formation in cooling towers and heat exchangers; 

4: Iron: It can foul equipment when coupled with phosphate;

5: Organic matter: It promotes the growth of microbes, which can lead to fouling, corrosion, and other system issues;

6: Silica: This mineral is known to generate hard scale formations;

7: Sulphates: Like chlorides, sulphates can be extremely corrosive to metals;

8: TDS (total dissolved solids): It induces scaling, foaming, and/or corrosion;

9: Total suspended solids (TSS): Undissolved contaminants that can cause scaling, biofilms, and/or corrosion.

Why is it necessary to treat cooling tower waters?

While precise water treatment procedures will differ depending on the application, typical cooling tower water treatment will include one or more of the following areas:

1: Managing Make-up Water

2: Filtration

3: Chemical therapy

4: Side-stream filtering

1: Make-up Water Treatment

Make-up water, which is used to replace evaporated and spilled water from the cooling tower, is frequently treated before being added to the system. Depending on the quality of the source water, hardness or silica may need to be removed, as well as the pH levels of the water adjusted. In these cases, water softeners from Netsol should be used, as well as automated pH control systems, to maintain consistent pH levels.

2: Filtration

You may remove suspended particles and some forms of organic matter from cooling tower water by running it through a filtering system. These particles and organic matter can contribute to scale, corrosion, and foaming. Filtration should be performed as the first step in the water treatment process because eliminating suspended solids upstream can help preserve ion exchange resins and membranes downstream from fouling.

3: Treatment with Chemicals

Chemically treating your water is necessary to balance the chemical qualities of the water and make it less prone to cause problems. Chemical treatments that are common include:

-Ion exchangers and water softeners

-Anti-corrosion and anti-scale agents

-Biocides and algaecides

-Defoaming agents

-pH adjusting agents

4: Filtration on the side-streams

If you intend to recirculate your cooling tower water throughout your system, side-stream filtration machines can assist in removing contaminants that may have reached your tower due to drift contamination or process leaks. Side-stream units remove suspended solids, organic deposits, and silt particles from your cooling tower water in modest increments. As a result, the likelihood of fouling or biological growth decreases, resulting in increased water and energy efficiency from less water discharged and less scale formation on any heat transfer surfaces.
