FROTEC ULPFT-4040 Ultra-Low Pressure BWRO Membrane Element
The ULPFT-4040 is an ultra-low pressure aromatic polyamide composite reverse osmosis membrane element developed by Huamo Environmental. Operating at approximately 2/3 of conventional low-pressure brackish water RO membrane pressure, it achieves over 99% salt rejection with excellent water productivity — ideal for energy-efficient municipal and industrial water treatment applications.
- Low energy consumption
- High filtration accuracy
- Large water output
- Strong anti-fouling
Product Introduction
The ULPFT-4040 is an ultra-low pressure aromatic polyamide composite reverse osmosis membrane element developed by Huamo Environmental. Operating at approximately 2/3 of the pressure required by conventional low-pressure brackish water membranes, it achieves a salt rejection rate of 99.2% or higher while delivering excellent permeate output under low-pressure conditions. Designed for treating surface water, groundwater, and municipal water with TDS up to 2,000 mg/L, the ULPFT-4040 is ideal for packaged drinking water production, residential and community water supply, and food and beverage processing applications. It features high permeate output, ultra-low operating pressure, and reliable salt rejection performance.
