Description
Summary:The Block and Hong biological phosphorous removal (BPR) process was installed at the Branson wastewater treatment plant, Mo., to ensure compliance with phosphorous limits of 0.5 mg per litre for the effluent discharges to Taneycomo lake. The factors considered in process selection, including performance, space constraints, costs, compatibility with existing plant and processes and biosolids generation and management are discussed and BPR and chemical precipitation alternatives are compared. BPR is explained and the processes installed which comprise the Block and Hong process followed by an oxidation ditch activated sludge process, the addition of liquid alum and effluent-polishing filters, are described. The problems encountered at startup and the modifications which have subsequently been made are described. The process regularly achieves a high level of phosphorous removal with only minimal chemical addition. Construction costs are presented.
