Phosphorus removal in a sewage treatment plant and plant biomass in an effluent receiving lowland stream
- 38 Downloads
In the period 1977–1981 a study was carried out in a lowland stream to investigate the effect of P-removal in a sewage treatment plant on the biomass production by aquatic macrophytes. Biomass development, the role of the sediment, the ‘natural’ phosphate concentrations of streams, the phosphorus, nitrogen and potassium content of plants were studied.
It was concluded that P-reduction in the sewage treatment plant did not lead to a reduction of the plant biomass.
