Cooling water

---

Corrosion, Scale, and Biofouling impacts heat transfer efficiency. Therefore, it is important to identify and adopt solutions for the cooling water system based on the most Cost-Efficient chemistry.

Corrosion

Corrosion causes severe damage to the equipment and reduces equipment life and efficiency. Corrosion Inhibitor is applied to reduce the rate of corrosion and avoid early replacement of tubes and heat exchangers. Corrosion Inhibitor works through precipitation or passivation method. Based on the water chemistry, corrosivity indices, operating conditions and limitations, the type of corrosion inhibitor is established and recommended.

Scaling

Scaling reducing heat transfer efficiency and causing secondary under-deposit corrosion. Scales are cause primarily by the over-saturation of dissolved minerals.

Scale Inhibitors are based on dispersion and distortion chemistries. It increases the solubility of the dissolved solids through charge modification and prevent aggregations by changing the structure of the crystallite.

Biological Fouling

Biological film reduces heat transfer efficiency and causes secondary under-deposit corrosion similar to scaling. In addition, the risk of health-related hazard such as legionella bacteria which is the cause Legionnaries Disease. Microbiological growth leads to biofouling issue (slime or biofilm). Biofilm acts as a thermal barrier which decreases heat transfer, increasing energy cost and under-deposit corrosion occurrence.

Tersus develops and customise solutions for the cooling water treatment through analytical studies of the system, water quality, limitations, and operating conditions.
