CAPACITY EXPANSION FROM 8.5 MLD STP (ACTIVATED SLUDGE TECHNOLOGY) TO 16 MLD STP (PVA GEL TECHNOLOGY) WITHOUT EXTRA SPACE.
A sewage treatment plant of capacity of 8.5 MLD based on the Activated sludge process was completed and commissioned in Municipal corporation, Vadodara. Today sewage generation capacity is increased in the zone and the STP is overloaded. A total capacity of 16 MLD STP is required as per current demand. Hence a 7.5 MLD expansion is required.
As the STP is situated in the populated area of city, it was difficult to allocate more space for expansion. Hence the expansion of 7.5 MLD in existing 8.5 MLD STP should be done in existing infrastructure only.
As the space is the major issue in this project, all the conventional technologies like MBBR & SBR cannot deliver the result. While MBR is economically not viable. PVA Gel based process is the only technology that can deliver the desired output considering the space & economic constraint.
