Abstract:

In Biological Nutrient Removal (BNR) plants designed for combined Nitrogen and Phosphorus (N & P) removal, often one nutrient competes with the other for organic carbon, which may result in less than optimal removal of both nutrients. However, a step feed process configuration at the Westside Regional WWTP (WRWWTP) in British Columbia, Canada has been demonstrated to achieve excellent combined N & P removal with the expectation that even lower limits can be achieved in the future with minor refinements to the treatment process. This process configuration is referred to as the ;amp;#x201C;Westbank” process and the flow sheet is illustrated in Figure 1.
