LG RO MEMBRANES

ES/UES Energy Saving Membranes

LG’s range of brackish water membranes offers high permeability at low operating pressures. The ultra-low pressure UES version is suitable for low salinity brackish feed water, with the higher pressure ES version suitable for low to medium salinity feed water. The energy-saving properties and unique TFN technology make these membranes an excellent choice for applications where reliability is essential, with significantly lower running costs than traditional membrane alternatives.

LG BW 4040 UES RO Membrane
The LG UES membrane offers an average rejection rate of 99% at pressures as low as 6.9 bar. It is an ‘extra low energy ‘ultra energy saving’ membrane and is a suitable alternative to Oltremare LOW4-4040, Axeon HF4-4040, Hydranautics ESPA4-4040 and Dow/Filmtec XLE-4040.

LG BW 4040 ES RO Membrane
The LG ES membrane offers an average rejection rate of 99.5% at an operating pressure of 10 bar. It is a low energy membrane and is a suitable alternative to Oltremare LOW2-4040, Axeon HF1-4040 and Dow/Filmtec LE-4040.
