The use of organic fraction of municipal solid waste hydrolysis products for biological nutrient removal in wastewater treatment plants

Experiments in a continuous UCT-bench scale plant using synthetic wastewate r, have been carried out to demonstrate the feasibility of using the biodeg radable organic fraction of municipal solid waste (BOF-MSW) as an easily bi odegradable C source for nitrogen and phosphorous removal. Yields obtained are quite good and the additional load introduced by the use of the ferment ation products of the BOF-MSW can be considered negligible. In addition, th e basic mass balances carried out, show that the amount of easily biodegrad able C-source needed to treat the wastewater produced by a given unit of pe rsons can be obtained from the amount of BOF-MSW generated by this unit, (C ) 1998 Elsevier Science Ltd.
