Enhancing biological phosphorus removal with glycerol
Water Science and Technology, 2010 An enhanced biological phosphorus removal process (EBPR) was successfully operated in presence of acetate. When glycerol was substituted for acetate in the feed the EBPR process failed. Subsequently waste activated sludge (WAS) from the reactor was removed to an off-line fermenter. The same amount of glycerol was added to the WAS fermenter which led to

Fixed film phosphorus removal – flexible enough?
Water Science and Technology, 2006 While biological phosphorus removal (BPR) has been practised for 30 years, up to recently it has been restricted mainly to activated sludge processes, with the corresponding need for large basin volumes. Yet, research with biofilm reactors showed that the principle of alternate anaerobic and aerated conditions was applicable to fixed bacteria by ...

Phosphorus removal using novel crystallisation technology
Water Science and Technology, 2006 A soy protein manufacturing facility was faced with the challenge of reducing its effluent phosphorus (P) content from 20–50 mg L−1 down to <2 mg L−1 total P without increasing soluble salt levels to comply with discharge and receiving water requirements.

Kinetics and Mechanism of Phosphorus Removal from Silicon in Vacuum Induction Refining
High Temperature Materials and Processes, 2012 Vacuum induction refining is a process that can be applied to remove phosphorus from molten silicon for the production of solar grade silicon. Pure silicon was doped by phosphorus to make molten silicon containing around 17 ppmw phosphorus.

Innovative phosphorus distribution method to achieve advanced chemical phosphorus removal
Water Science and Technology, 2008 Since November 2006 a large-scale research project has been carried out at Wastewater Treatment Plant (WWTP) Leiden Zuidwest (within the Rijnland District Water Control Board). This research focuses on advanced removal of nutrients (phosphorus and nitrogen), heavy metals and priority hazardous substances from WWTP-effluent with different treatment ...
