• Function
Reverse osmosis is a membrane process for desalting saline water by application of hydrostatic pressure to drive the feed water through a semi permeable membrane while a major portion of its impurity content remains behind and is discharged as waste. The pure water (known as permeate or product water) essentially emerges at near atmospheric pressure, while the waste practically remains at its original pressure. In this process the permeate loses its salt content to the brine, which get highly concentrated. The operating pressure ranges from (300-400) psi.
MEWT has designed a wide range of R.O systems from 1000 – 1,300,000 GPD .
