Biosol Products help remove Fat, Oil & Grease from Sewer Catchments


Fat, oil and grease accumulates in sewers and wetwells causing:
  • Offensive odour
  • Sewer blockages and over flows
  • Increased pump head, pumping cost and Greenhouse Gas Emissions
  • Sewer pump failure and burn-out
  • Increased rodent food supply and community health risk
  • Blocked air valves and costly cleaning
  • Costly maintenance
  • The risk of legal action and heavy fines.


Biosol products slow down microbial activity in sewer catchments causing the disintegration of the microbial slimes. It appears that these microbial slimes are necessary for the adhesion of fat, oil and grease (FOG) in sewer mains and wetwells as shown in the photo below.



The FOG released from the sewer pipe and wetwells, ends up at the treatment plants as shown in the photos below. At the treatment plant FOG is processed as usual, however the rate at which FOG is released in the sewer catchment is controlled by the Biosol dose rate. This ensures that excess FOG will not overload the treatment plant during initial dosing.





Releasing FOG from sewer pipes, will reduce the pumping head, (energy cost) while reducing the risk of spills and sewer overflows.
