Most of the ETP till recently were based on the design philosophy of producing safe disposable water. Broadly the technology involved in achieving such disposable water includes primary and secondary treatment. The biggest deficiency of this process is that it consumes lots of money (capital & operational cost) without any financial gain. Incorporation of membrane based technology after primary and secondary ensures that reusable grade water can be produced. GMS provides package solution for such schemes. Waste Water Treatment Plant installed with membrane process not only reduces (in many cases eliminates) the waste water but also helps to reduce load of drinking water which results in a better environmental management.
