The upgrade will help the refinery meet tightened discharge regulations
Koch Membrane Systems (KMS) has been selected to provide Puron membrane bioreactor (MBR) modules for the upgrade of a wastewater treatment plant at a refinery in Russia. The system is designed for an average flow of 24,000 cu meters per day (6.3 million gal per day), with peaks of up to 28,800 cu metrers per day (7.6 million gal per day). Start-up is scheduled for 2015.
The existing conventional wastewater treatment plant at the large oil refinery had to be replaced by a membrane bioreactor system to meet tightened discharge regulations. Ninety percent of the wastewater fed into the MBR is industrial, while the remaining ten percent is sanitary wastewater generated by the refinery’s camps and offices.
KMS’ submerged Puron modules were selected because of their energy efficient design, the small footprint requirements, and KMS’ engineering support during the bidding and project phase. The customer was also impressed with the strong braided fiber, which reduces the risk of fiber breakage.
KMS’ scope of supply includes the Puron PSH1500 membrane modules, all pumps and blowers, and the complete equipment package for the bioreactors with fine bubble diffused aeration, mixers and circulation pumps. Also included are complete MBR plant instrumentation, process logic control, motor control cabinet and chemical dosing systems, as well as installation and commissioning assistance.
