Enhancement of phosphorus removal in a low temperature A2/O process by anaerobic phosphorus release of activated sludge
An anaerobic phosphorus release tank was introduced to an anaerobic–anoxic–aerobic (A2/O) process treating domestic sewage to enhance the phosphorus removal at low temperature. Phosphorus release of the activated sludge from the second sedimentation tank was evaluated at 14 °C by batch cultures, and the nutrient removal in the modified low temperature A2/O process was ...

Dissolved-air flotation associated with an anaerobic reactor, as applied to sewage treatment
This paper presents the results of a study performed with a pilot sewage treatment plant consisting of an aerobic reactor followed by a flotation unit. To coagulate the anaerobic effluent, different ferric chloride dosages were applied by adopting two approaches: applying constant dosages during the essay and varying the dosages according to the anaerobic effluent turbidity. To obtain more than ...

Evaluation of a novel oxidation ditch system for biological nitrogen and phosphorus removal from domestic sewage
A novel oxidation ditch system using anaerobic tanks and innovative dual dissolved oxygen (DO) control technology is proposed for biological nitrogen and phosphorus removal from domestic sewage. A continuous bench-scale experiment running for more than 300 days was performed to evaluate the system. Monitoring and controlling the airflow and recirculation flow rate independently using DO values at ...

How can money be made from sewage?
The water industry’s seen a clever development take place from Vancouver based company Ostara who has found a way to not only make money from sewage, but also reduce water pollution. The new technology is capable of harvesting phosphorus and ammonia from municipal sewage treatment plants and then create fertiliser pellets from the harvest! So what are the benefits of this new process? ...
