BW 400 AFR G2
The NanoH2O BW 400 AFR G2 is a premium anti-fouling brackish water reverse osmosis (BWRO) membrane element with a 34 mil low differential pressure (low-dP) feed spacer. This design minimizes pressure drop (ΔP) and optimizes hydrodynamics across the active membrane surface. It delivers a stabilized salt rejection of 99.7% and a nominal permeate flow rate of 11,500 GPD (43.5 m3/day). The BW 400 AFR G2 enhances permeate water purity, reduces Clean-In-Place (CIP) chemical cleaning frequency, lowers specific energy consumption, and extends overall system service life.
