The paper presents the results of experimental studies on the efficiency of additional treatment of industrial waste water of the plant “Motor Sich JSC” from petroleum products with modern biotechnology of waste water treatment using the fibrous carrier “VIYA”. The comparative analysis of the efficiency of additional treatment of industrial waste water of the plant from petroleum products using the artificial fibrous carrier and the adsorbent “Ecolan” has been carried out.
Identifying the potential of using the immobilized microorganisms and periphyton organisms installed on a fibrous carrier of the “Viya” type for biological treatment of industrial wastewater discharged by the enterprises of the mining and metallurgical complex

The article deals with the problem of surface water pollution by untreated industrial wastewater, namely oil products, using clarifiers applied by the “Zaporizhstal” PJSC plant in the city of Zaporizhzhya. The survival of gram-positive bacterial colonies and periphyton immobilized on a fibrous carrier in the wastewater of the sludge collector was experimentally observed, taking into account the optimal ambient temperature ideal for the life of microorganisms (within the range of 25.0‒27.5 ○C during the summer period).
