Thames Water have recently built a demonstration‐scale biological nutrient‐removal plant at Beckton sewage‐treatment works to provide (a) operational experience of nutrient removal, and (b) accurate design and cost information. The paper (i) outlines the basic principles of biological nutrient removal, (ii) describes the plant layout at Beckton, and (iii) presents results from the first three months of operation. The plant has removed over 50% of both nitrogen and phosphorus present in the settled sewage but has not been able to meet consistently the most stringent standards proposed by the urban waste water treatment Directive. Periods of good performance are compared with periods of poor performance, and differences in operating conditions are highlighted. From these findings, steps to improve performance are indicated and will be included in the future operational programme.
