Extended aeration : a comparative study between prefabricated reinforced fiberglass and concrete cast in-situ plants [PDF]
The choice of wastewater treatment plants for any application depends on the quality of raw sewage, the required quality of treated water and the economics resources available to pay for both capital cost and operating cost of the treatment plants.

Direct nanofiltration of wastewater treatment plant effluent [PDF]
Membrane technology, especially nanofiltration, is seen as a suitable technology to polish WWTP effluent to EU WFD standards and consequently produce an effluent quality suitable for agricultural or (in)direct potable usage.

Partial denitrification providing nitrite: Opportunities of extending application for anammox
Anaerobic ammonium oxidation (anammox) has been extensively investigated for cost-efficient nitrogen removal from wastewater. However, the major issues of nitrate (NO3−-N) residue and instability in the current combination of nitritation and anammox ...
