Research of Oily Wastewater Treatment by means of Membrane Methods

Abstract

Membrane bioreactors nowadays are intensively applied in wastewater treatment worldwide. Such type of treatment systems has a large scope of implementation at facilities of different capacity. Undoubtedly, the use of MBR for the treatment of industrial wastewater greatly simplifies the process with significant fluctuations in the concentrations in the original wastewater and the presence of "volley discharges". BMR technology-bio-reactor with activated carbon and membrane separation is also of a certain interest. The use of this technology largely solves the issue of post-treatment of refinery wastewater, but returns us to the problem of high operating costs. An alternative to biological methods of wastewater treatment of the refinery can be the use of reverse osmosis plants for this purpose, providing the necessary degree of purification for a number of indicators. The method of reverse osmosis (RO) is already widely used in schemes of water treatment, drinking water supply and post-treatment of wastewater for reuse.
