Biofilm is the extracellular polymeric substances produced by bacteria along with the bacteria that produce it. The formation of biofilm, the nature of biofilm and the difficulty in inactivating biofilm bacteria is well known. Bacterial biofilm, or slime as it is more commonly called, causes a number of problems in cooling systems known as biofouling. |
Losses in heat transfer translate to losses in production or increased energy costs. Increases in corrosion result from biofilm directly or indirectly through the promotion of anaerobic bacteria, Desulfovibrio desulfuricans. Bacterial biofilm may also harbor pathogenic organisms such as Legionella. |
Effects of Biofouling layer on heat exchangers |
 |
- Add a further Heat transfer resistance tending to reduce the thermal performance
- Reduces flow area & thereby flow velocity
- Increase in Back Pressure
250 µm thick fouling layer results in 50% reduction in Heat Transfer

The Menace of Algae
Algae require sunlight & water for growth. Both are abundant in cooling pond water. As a result cooling towers present an ideal environment for growth of algae. Algae is a very common problem with cooling tower users. It not only affects the nature of water but also causes clogging of water circuits.
Why ENCEE CHLOR?
- Control of Slime to maintain efficiency of Exchanger
- Prevent & Control Algae Growth
- Avoid Bacterial Corrosion of water circuits
- Control Legionella Bacteria causing Legionnaires Pneumonia
