Volume and load of sewage treatment plants State of the ...

2021-11-4  Nitrogen load was lower in 2014 and 2016, attributed to lower rainfall and lower treated sewage volumes, particularly from plants in SEQ. Sewage treatment plants released 490 tonnes of phosphorous into coastal waterways in 2019. There have been significant decreases in phosphorous load since 2015.

Secondary treatments - Salher

The nitrification-denitrification treatment plants are secondary treatments by low-load activated sludge, with biological nitrogen removal (nitrification-denitrification) and clarification process. Optionally, a phosphorus removal system is available. We find two models that differ from each other in the clarification process: the CHC-OXI-REC-C-ANOX treatment plant carries out its ...
