Wastewater plant upgrade in Russia to utilise KMS products

Koch Membrane Systems (KMS) a developer and manufacturer of membranes and membrane filtration systems, has been selected to provide PURON MBR modules for the upgrade of a wastewater treatment plant at a refinery in Russia.

The system is designed for an average flow of 24,000m3 per day (6.3M GPD), with peaks of up to 28,800 m³/d (7.6M GPD). 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 10% 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 modules also have strong braided fibre, which reduces the risk of fibre 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.

Russia's water quality improvement programme is creating a growing demand for MBR installations. The new water treatment plant will be one of the larger MBR references for KMS in the country, with others to follow.
