Abstract:
A process of treating liquid contaminated with organic compounds, BOD, COD , N containing compounds and/or P containing compounds, said process comprising the steps of:(a) passing the liquid through a P-removal bioreactor comprising an immobilized microbial consortia which are charged or recharged with a carbon source present in the liquid; (b) passing the effluent from step (a) through the P-removal bioreactor which has been charged or recharged from step (a) under conditions which allow the microbial consortia to uptake and store P compounds; (c) removing the wastewater from the P-removal bioreactor and providing a P-release solution effective to cause the microbial consortia to release the P previously stored; and (d) removing the P-release solution containing the released P from the P-removal bioreactor.
