In this paper was studied the possibility of use the sludge from wastewater treatment plant in agriculture. Under current legislation the sludge from treatment plants of Prahova county is divided into: sludge washing separator sludge from oil / water, sewage interception, sludge or emulsion desalination residues from stations of wastewater and drinking water treatment, refusals to grills / screens wastewater treatment plants, waste from desanding mixtures of fats and oils from separating fat from wastewater, sludge from industrial wastewater, sludge from municipal wastewater treatment solutions, sludge from regeneration of ion exchangers. In this study were determinate quality characteristics from the effluent and sludge: pH, BOD – total biological oxygen demand), BOD5, COD - chemical oxygen demand, SS - suspended solids. N - nitrogen, (TNK), P – phosphorus, specific resistance to filtration. This results show a possibility to use the sludge and effluent from wastewater treatment plant in agriculture according with national legislation. Testing time was about 12 weeks. It was calculated the risk factor of the process and has been studied the possibility of reducing the risk through appropriate measures.
