Brackish Water (BW) RO Element

Industrial Brackish Water RO Membrane Series

Puroxy Industrial Brackish Water Ro Membrane Series (BW) can achieve high water production rate and high desalination rate in a relatively low operating pressure with low energy consumption. its operating pressure can be as low as imp a (150psi), which makes it suitable for desalinating water with salt content less than 5000ppm. it is widely applied in food processing, drinking water, electricity water supply, electronics and biotechnology industry, pharmaceuticals and other fields.

Law Pressure (LP) RO Element

Industrial Low Pressure Ro Membrane Series

Puroxy ultra-low pressure series (LP) has excellent performance in water production rate And desalination rate. It performs as well as bw series even though under ultra low Pressure. Its operating pressure is 0.76mpa (110psi) only. So it is good choice for dealing Water with salt content less than 1000ppm. It is widely used in irrigation of city landscape And agriculture, drinking water, municipal water supply, commercial pure water treatment, Hospital, laboratory, home use etc.
