BW-LP Membranes – Low Pressure Reverse Osmosis for Brackish Water

BW-LP membranes

BW-LP membranes are designed for the treatment of low-salinity brackish and tap water, ensuring high filtration efficiency even at low operating pressure.
Their low energy requirement makes them ideal for residential, commercial, and industrial reverse osmosis systems.
Perfect for removing dissolved salts, heavy metals, and contaminants. Available in standard 2540 and 4040.

Compatibility

E-Mem
(old / new)		 Dow/Filmtec/Dupont GE/Desal Hydranatics
EM-RO-2540-LP / EM-RO-2540-LP TW30-2540
(DOW-branded model offers a higher flow)		 AG2540TM
EM-RO-4040-LP21 / BW-4040 BW30-4040 AG4040TF CPA2-4040
EM-RO-8040-LP22 / BW-400 BW30-400 AG8040F 400 CPA3-8040
(On the Hydronautics model, salt rejection is 2% higher)
E-Mem
(old / new)		 Toray CSM Membranium
EM-RO-2540-LP / EM-RO-2540-LP RE2540CE
(E-Mem model offers a larger filter surface area, with 0.5 per cent more rejection and higher flux)
EM-RO-4040-LP21 / BW-4040 TM710D
(on the E-mem model there is a 28mil spacer, while on the Toray model it is 31mil, the flux of the latter is therefore slightly higher and the rejection 0.3% higher)		 RE4040-BE KC 4040-C
EM-RO-8040-LP22 / BW-400 RE8040-BE KC8040-C
