Reverse Osmosis

Osmosis is a process where water diffuses from an area of higher to lower concentration until equilibrium is achieved between two solutions. Reverse osmosis (RO) is achieved by an increase in osmotic pressure to the lower concentrated feed water solution. The water molecules diffuse from an area of lower to higher concentration.

A reverse osmosis membrane will remove up to 99% of all microorganisms, pyrogens, total dissolved solids, and organics from the feed solution at a molecular weight of 200 or greater. Reverse osmosis membranes have a pore size of 0.001 microns.

L&T Technologies' reverse osmosis systems are skid mounted, with all of the equipment fastened to the epoxy coated structure. The reverse osmosis process, in most cases, runs at pressures between (200-1000 PSI).

Reverse osmosis membranes are arranged in either stainless steel or fiberglass housings. In most cases, the piping will be 304 stainless. If the possibility of corrosives is present 316 stainless steel or Alloy 20 will be utilized. High and low pressure switches protect and extend the life of the RO elements and the high pressure feed pump. A total dissolved solids (TDS) meter monitors the feed and permeate (clean water) streams.

L&T Technologies has a full line of standard reverse osmosis units. We can also custom design our filtration units with the use of our on site pilot testing labs.
