LEFILTER is the filter element supplier, manufacture of DOW Filmtec, Suez (GE) & Hydranautics Membrane.

We are a trustworthy organization in the market, actively engrossed in offering a wide gamut of Industrial RO Membrane to the clients. These membranes remove or reduce arsenic, barium, chromium, cadmium and several other impurities. Also, these are checked on numerous parameters in order to deliver flawless range at clients end.

DOW brand RO filter Elements contain a nanofiltration membrane that is designed to selectively remove sulfate from seawater used for waterflood injection operations in offshore oil production, helping to prevent barium and strontium sulfate scale precipitation and to

control/mitigate souring in reservoirs containing barium and strontium. This nanofiltration membrane, operating very efficiently at lower pressures, also removes all particles greater than 0.001 microns, resulting in high-quality injection water free of

silica and bacteria, thereby ensuring continued injection rates reflective of initial reservoir conditions.
