HM RO Membrane Elements (4 / 6 / 8 inch)

Name: HM RO Membrane Elements (4 / 6 / 8 inch)
Brand: Xinnian
SKU: BW / LP Series

BW / LP Series

The HM BW (brackish water) series uses aromatic polyamide composite membranes with low operating pressure, high flow and good rejection, and removes dissolved salts, TOC and SiO₂ effectively for high-purity water in electronics and power generation. The LP (low pressure) series suits surface water, groundwater and municipal water with salinity up to roughly 10,000 ppm.

Key Features

BW and LP series covering brackish and low-salinity sources
Low operating pressure, high flow and low energy consumption
Good TOC and SiO₂ removal for high-purity front ends
4-inch, 6-inch and 8-inch sizes for flexible replacement

Frequently asked questions

Are these membranes compatible with standard 8040 housings?

Yes, they follow the standard 8040 / 4040 dimensions and fit common fibreglass pressure vessels.

What salt rejection can I expect?

98.5–99.5% nominal rejection on 2000 ppm NaCl at standard test conditions; actual performance depends on pressure, temperature and recovery.

Do you provide element loading drawings?

Yes, we issue an array layout with the quotation so your team can load vessels correctly.
