In many cases, waterworks waste alum sludge is disposed of by discharging it into a stream. In this investigation the disposal of alum sludge to activated sludge systems treating municipal sewage is investigated. The advantage is that it is a better method of alum sludge disposal, and moreover the addition of alum sludge removes phosphorus from the wastewater through chemical precipitation. Two long sludge age (20 days) Modified Ludzack Ettinger (MLE) predenitrification systems receiving unsettled municipal wastewater at a controlled concentration of 500mg COD/l as influent were operated for a period of 305 days, one as an Experimental system and the other as a Control system. The anoxic mass fraction was large (70), to mimic many long sludge age nitrification/denitrification systems in operation in South Africa. Nitrate was added into the anoxic reactors to maintain anoxic conditions so that biological excess phosphorus removal would not take place and interfere with the chemical removal performance. 2014-10-11T11:56:37Z 2014-10-11T11:56:37Z 1992 Master Thesis Masters MSc http://hdl.handle.net/11427/8299 eng application/pdf Department of Civil Engineering Faculty of Engineering and the Built Environment University of Cape Town |
