Abstract: front page image
(EN)The invention relates to a treatment method of reducing the production of biological sludge from one or more urban or industrial wastewater purification stations. The invention is characterised in that the sludge reduction method is removed from the biological system of the purification station, by providing separate means which are used for sludge reduction and for the precipitation treatment of the phosphorous accumulated in the sludge arriving from a sanitary installation.
