Abstract

The development of a closed-circular economy is an opportunity to increase its competitiveness and reduce operating costs. Repeated use of water taken from the environment in industrial plants has been used for many years. An important aspect is to maintain the required physicochemical parameters throughout the entire process. The required physicochemical parameters should be maintained by applying appropriate purification processes. The use of a closed cycle of water circulation in production processes allows reducing the load of sewage affecting the environment. Mechanical treatment of wastewater, e.g. through the use of the sedimentation process, is slow and often requires the support of coagulation or flocculation processes, and thus the use of auxiliary chemistry. At the same time, to increase the efficiency of the sedimentation process, it is possible to use multiflux fillings to accelerate the sedimentation process without the use of chemicals. The article presents the results of the use of multiflux fillings in the sedimentation process on the example of selected industrial suspensions.
