Physicochemical technology of pretreatment of dairy waste water using natural waste

Abstract

The growth in the production of dairy products entails the problem of treating wastewater from the operation of dairy plants. This article discusses the possibility of using a purification technological scheme using sorbents from natural waste, which is an alternative to the traditional one, which includes a biological stage. In this study, activated biochar from rice husks and graphite are used as sorbents. As a result of purification according to the proposed scheme, the quality of the treated water corresponds to the normative indicators when discharged into the city sewage network.
