Micro-fouling:

Comes in the form of a layer of slime over the surface of heat exchanger plates and tubes and can reduce heat transfer efficiency by as much as 25%. It can also accelerate corrosion and result in a situation where maintenance is required more often than usual with subsequent increases in running costs

Macro-fouling:

Barnacle and mussel growth inside seawater pipes and cooling systems can gradually restrict seawater flow and reduce the flow and heat transfer efficiencies. In extreme cases, pipes and valves can become completely blocked, resulting in shut-down of systems, damage to equipment, and, consequent loss of production time

Continuous and shock dosing:

Continuous and shock dosing are usually considered for the effective control of micro and macro-fouling in seawater applications. During continuous dosing, a low chlorine dosing is maintained. It provides protection against the majority of biofouling. Unfortunately macro organisms can become resistant to this low chlorine dosing and require a much higher chlorine dosing. During shock dosing, a much higher chlorine dosing is applied only for a short time and repeated at certain fixed intervals. This will ensure complete protection against all micro and macro-fouling

CHLOR GENERATORS LTD offer a complete range of dosing strategies to ensure optimum anti-biofouling protection at the lowest chlorine usage
