Technological Innovation to Reduce the Negative Environmental Impact of Industrial Wastewater

Abstract

Rational use of natural resources and protection of water bodies is an actual problem of the modern world. Due to the rapidly developing industry, wastewater which contain high concentrations of suspended substances and organic pollutants is discharged to water bodies in a large volume.So design improved treatment facilities that ensure high quality of treated water is an important task.Biomembrane technology is a promising direction in water treatment, providing high efficiency of treatment at minimal cost. Compared to the traditional treatment scheme, it allows you to avoid the use of secondary settling tanks by separating the active sludge from the treated wastewater on the membranes. Due to the very small size of the membrane pores, almost complete removal of suspended substances and microorganisms is achieved. A bioreactor with an external arrangement of the membrane module provides high specific capacity.The small-bubble aeration system in the aeration tank ensures the maintenance of dissolved oxygen at a concentration of 2-3 mg / l for the correct course of the nitrification and oxidation of organic substances. The combination of biological treatment and membrane separation ensures high operational reliability and durability.This technology is used in various industries, but it is most widely used in the food and oil refining industries due to the high content of organic pollutants, which are mostly removed by this installation.The use of biomembrane technology is economically advisable for designing treatment facilities for industrial wastewater treatment from organic pollutants.
