FERTILISING AGRICULTURAL FIELDS WITH THE SLUDGE RESULTED FROM SEWAGE WATER TREATMENT STATIONS PUBLISHED

Laura Constantinescu
The sludge resulted from urban sewage water treatment stations must be treated in order to be less harmful for the environment. The paper presents the chemical characteristics of the sludge resulted from urban and rural sewage water treatmentstations. These chemical characteristics vary for both the fresh and the fermented sludge. This sludge can be used to fertilize the agricultural fields only after knowing the existent quantity of nitrogen, phosphorus and potassium in the soils. The attempt to fertilize the agricultural fields with the sludge resulted from sewage water treatment stations is a component  of  the sustainable development   of  public health.
