The article studied modern cleaning methods and technological schemes of enterprises of the fat-and-oil industry. Based on literary sources, the effi ciency of wastewater treatment by physicochemical treatment methods has been investigated. Reagent pretreatment of wastewater is widely used, and research focuses on the selection of optimal reagents and doses. A modern method for the treatment of fat and oil containing wastewater is biomembrane technology. Classic treatment schemes are often unable to achieve regulatory requirements for the quality of treated wastewater; therefore, the use of membrane bioreactor technology may be in demand for treating food wastewater. The problems of using various methods of purifi cation of fat-and- oilt wastewater are identifi ed. The economic effi ciency of the proposed cleaning methods is determined.
