What is Reverse Osmosis and How Do Reverse Osmosis Plants ...

 · The currently emerging method which is gaining ground for producing fresh water form the sea water or brackish water is by the Reverse Osmosis (RO) process. In the RO process, water at high pressure passes through very fine membranes that allow only the water molecules to pass through. Plants basically consist of two phases. The first phase is a pre-treatment plant.

In most RO wastewater treatment plants, the flux rate for the RO process is chosen in the range of 17 – 20 lmh. This is based on extensive research at pilot tests and commercial plants. Flux rate is important in a RO system because it governs the crossflow rate and mass transport rate through the membrane.

Fundamentals of Membranes for Water Treatment

polymers with voids created by an extrusion and stretching process. First, the material is extruded near its melting temperature using a rapid draw-down rate. Then, the extruded material is cooled, annealed, and stretched up to 300% of its original length. This stretching process creates slit-like pores ranging in size from 200 to 2500 Å.
