Abstract

In waste water treatment using biological treatment processes, normally phosphorous, nitrous compounds as well as organic matter are removed. It is also important to remove or kill pathogens that otherwise could cause diseases. The surplus of bio-sludge is used to produce biogas. In the paper four different alternatives for system design and operations of systems was discussed. The alternatives integrate the waste water treatment and irrigation of farmland using the water taken out from different positions in the wastewater treatment plant.
