Hydranautics NANO-BW Membrane

Quality parts at an exceptional value
Product Description

Nano BW are high performance nanofiltration membranes ideal for treatment of low salinity surface or ground waters containing high molecular weight organics or pesticides. They provide 50%-90% salt rejection with ultra-low-pressure operations, increased energy savings, and significantly lower installation and operating costs.
