Russian oil company Bashneft is pilot testing GE’s ZeeWeed 500 ultrafiltration wastewater treatment system, GE announced on Monday, as part of plans to spur the biological treatment of sewage water from the Bashneft-Ufaneftekhim oil processing complex and other enterprises of the northern industrial block of Ufa.

Bashneft has selected ZeeWeed’s membrane bioreactor (MBR) technology, electrodialysis reversal (EDR) and reverse osmosis (RO) technologies as well as adsorption on activated carbon for the pilot testing. These tools allow sewage purification and treated waste water to be reused. The use of a set of purification methods enables implementation of a closed-cycle principle and the minimisation of water intake requirements.

A distinctive feature of GE’s purification is the absence of preliminary clarification tanks and secondary clarifiers. At the exit from the aeration tanks, the activated sludge is separated from treated water using ZeeWeed 500 ultrafiltration membranes. Dehydration of oil sludge, precipitation and excess sludge is performed on compact centrifuges. This makes it possible to reduce the area of purification facilities and exclude any chance of contaminant release into the environment.

The testing is being conducted in cooperation with the Institute of Petroleum Refining and Petrochemistry of the Republic of Bashkortostan as a part of preparations for a modernisation project for biological treatment plants (BTP) of the Bashneft-Ufaneftekhim branch.

“The innovative GE solutions minimise water intake requirements and minimise the risk of oil and oil products entering the ground and subsurface waters. We are confident that upgrading the water treatment facilities is a genuine step on the way to sustainable development for all of Russia’s oil industry.” said Chris Jeffery, region executive, Europe & Russia/CIS, engineered systems, GE Power & Water.

“We hope that GE’s advanced technology will help… make the water of the Belaya River cleaner, which will be beneficial for all the people of Bashkortostan,” said Viktor Gantsev, senior vice president, OJSC Oil Processing Joint-Stock Company Bashneft for petroleum processing and petrochemistry.
