Frankfurt (Germany): GATE Information Service and Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ) GmbH URL [Accessed: 03.06.2019]The introduction of oxygen into wastewater for nitrification requires a large amount of energy. Furthermore, the carbon source is often limited in wastewater, so purchasing of carbon source (typically methanol) is necessary too. A newly discovered anaerobic ammonium oxidation (Anammox) may circumvent the limitations and open up a new possibility for nitrogen removal from wastewater. The alternative approach is a microbiological involved activity, which requires less energy and enables more efficiency on N removal.

This manual contains extensive information on the principles of biological nutrient removal and chemical phosphorus removal to serve as the basis for design. A detailed description of technologies, both conventional and emerging, serves as a resource for preliminary technology selection.

In 1999, the responsible bacteria were positively identified. These slowly growing microorganisms belong to the order Brocadiales and are affiliated to the Planctomycetes. Cultivation of these bacteria at sufficient biomass density and rate, as well as the lack of pure cultures, has challenged the study of these extraordinary organisms. Membrane reactors have made the cultivation of up to 95% enriched cell suspensions of Anammox bacteria possible.

The aim of the project was to reduce water consumption and limit the wastewater flowing to the public sewer system, of which the largest part is discharged without treatment.

Many of the internally displaced persons camps were located in urban neighbourhoods with high groundwater, making onsite sanitation extremely difficult. In response to these unique conditions a small local organization, SOIL, partnered with Oxfam Great Britain to pilot urine diversion EcoSan toilets in camps throughout Port-au-Prince. This briefing paper covers this pilot project from March 2010 through March 2012. During that 2-year period, SOIL’s toilets served over 20,000 people and treated more than 400,000 gallons of human waste, converting it to rich compost.
