OREANDA-NEWS. September 21, 2012. Industrial and Domestic Waste Water Treatment Unit implemented at TANECO Oil Refining and Petrochemical Complex in Nizhnekamsk, received a high appraisal at the republican level. This project was awarded a diploma of contest “Environmental Leader” for "Implementation of energy-saving and environmentally efficient technologies of collection and processing of secondary resources.

TANECO WWT Unit does not have any analogues in Russia, where high technologies of known domestic and foreign companies have been combined. Traditional and advanced methods of treatment applied, such as membrane bioreactors, reverse osmosis, sorption, and ultraviolet disinfection, ensured the principle of "closed-loop" and allowed to minimize the necessary amount of water intake.

A distinctive feature of the treatment process is the lack of primary and secondary settlers. In the aeration chamber outlet the activated sludge is entrapped by the membrane bioreactors. Compact centrifuges dehydrate the oil sludge, settled sludge and waste sludge. WWT Unit area was reduced up to 9,2 hectare, and the possibility to discharge pollutants to the atmosphere was completely eliminated.

Design capacity of the Industrial WWT unit major lines – 2100 m3/h. Efficiency of treatment in different parameters makes from 87 up 99 percent. It’s also very important that WWT facilities are located on the same site with the major production facilities. Contaminated industrial waste water does not have to be transported to big distances, excluding the risk of chemical sewage pipeline rupture and, as consequence pollution of soil, water and atmosphere in Nizhnekamsk municipal area.

It terms of economic efficiency this WWT Unit is also a unique one. Within the year it will be possible to reduce the financial costs of the company by eliminating constant consumption of fresh water from the Kama river, excluding those payments that the company would inevitably spend on environmental activities in case of routing all effluents into water pools.

This environmental award is not the first for the company. In 2009 OJSC TANECO was declared a winner of VI All-Russian Contest "National environmental award" in nomination "City ecology" for development of Project on Unified sanitary- protected zone of Nizhnekamsk industrial area. In 2010 the company was awarded the first prize in the republican contest "Environmental leader" in nomination "Implementation of energy-saving and environmentally efficient technologies of collection and processing of secondary resources" among the Russian companies. In 2012 OJSC TANECO was recognized as one of the top 100 enterprises of Russia in the field of ecology and environmental management.
