On March 2009 Hydrotech Engineering OOO signed a contract for the design and execution of the Industrial Effluent Treatment Plant for a softdrinks production plant in the city of Kulebaki. The design wastewater flow is 1000 m3/day, and the main process is based on a Membrane Bio Reactor (MBR), applying the state of the art sidestream air-lift ultrafiltration technology in order to achieve the strict effluent requirements.
   The plant is expected to be in operation by the end of September 2009.
