FROTEC LPFT-4040 BWRO Membrane Element
The LPFT-4040 is a low-pressure aromatic polyamide composite reverse osmosis membrane element developed by Huamo Environmental for desalination of surface water and groundwater. Achieving a salt rejection rate of up to 99.3% with high permeate flow, it is ideal for treating brackish water, surface water, and groundwater with salinity under 5000 mg/L for municipal, industrial, and commercial applications.
- Low energy consumption
- High filtration accuracy
- Large water output
- Strong anti-fouling
Product Introduction
The LPFT-4040 is a low-pressure aromatic polyamide composite reverse osmosis membrane element developed by Huamo Environmental for desalination of surface water and groundwater. It achieves a stable salt rejection rate of up to 99.3% while maintaining high permeate output. Designed primarily for treating brackish water, surface water, groundwater, and municipal water with TDS up to 5,000 mg/L, the LPFT-4040 is widely used in electronics, power generation, municipal drinking water, chemical processing, pharmaceutical pure water production, as well as wastewater reuse and concentration applications.
