A sample of return activated-sludge (RAS) was collected from a municipal wastewater treatment plant. RAS consists of the mixture of old and new aerobic bacterial cells, which have settled out in the settling tank over a period of time. The activated-sludge was introduced into a bioreactor vessel to undergo treatment with Butane BiostimulationTM for a period of approximately three days. The results (above) showed a significant reduction in both Total and Settleable Solids. In addition, it is remarkable that the odor associated with the wastewater sludge sample disappeared almost immediately upon treatment with butane.
Butane enhanced treatment of wastewater may be conducted as a modification of existing aeration tanks in municipal or chemical wastewater treatment facilities or as stand alone or ancillary treatment reactors. The process may be used to reduce solids in any wastewater effluent. Butane BiostimulationTM may also be applied to abate nuisance odors associated with wastewater liquids/solids.
