LG Membranes & Reverse Osmosis Purification


Reverse Osmosis is a process in which pressure greater than the natural osmotic pressure is applied on the high concentration side of the membrane, forcing the water to travel through the membrane from the higher TDS to lower TDS chamber, thus ‘reversing’ the natural tendency of water flow. RO reduces pollutants resulting in clean, usable drinking water.

Benefits of LG Chem NanoH2O™ RO Membranes


The design of the dizzer® membranes ensures optimum throughflow combined with top-class water purification. The dizzer® membranes are capable of operating without the use of additional housings which allows for significant savings to be made on piping, valves, fittings, and installation engineering, which can result in investment costs being up to 20% lower than for pressure pipe technology. Other benefits include:

  • Create Drinking Water from Seawater
  • Stabilized salt rejection of up to 99.85%
  • Boron Rejection up to 93%
  • Improved permeate quality without increasing operating pressure
  • Reduced energy cost without sacrificing the permeate quality
  • Reduced capital and operation costs for multi-pass SWRO systems
  • LG Chem NanoH2O™ RO membranes are Standard 61 certified by NSF international for the production of drinking water.
