The accumulation of microbiological slimes biofilm and general bio-fouling in cooling water systems reduces system efficiency increases operating and maintenance costs. If ignored leads to under deposit and pitting type of corrosion. Our synthetic organic Biodispersant is effective in removing dead algal and slime mass from cooling system. It has a capacity to penetrate inside the thick algae mats on the cooling tower deck or fills and help the biocide to penetrate the biomass. It also has a deterrent effect and it cleans the system on line.
