FROTEC ULPFT-8040 Ultra-Low Pressure BWRO Membrane Element
The ULPFT-8040 ultra-low pressure aromatic polyamide composite RO membrane operates at approximately 2/3 of conventional low-pressure membrane pressure while achieving over 99% salt rejection. Designed for large-scale applications requiring energy efficiency, this 8-inch membrane excels in municipal water treatment, industrial pure water production, and brackish water desalination.
- Low energy consumption
- High filtration accuracy
- Large water output
- Strong anti-fouling
Product Introduction
The ULPFT-8040 is an 8-inch ultra-low pressure aromatic polyamide composite reverse osmosis membrane element developed by Huamo Environmental. Operating at approximately 2/3 of conventional low-pressure membrane requirements, it achieves a salt rejection rate of 99.0% or higher with excellent permeate production under reduced pressure conditions. Designed for large-scale applications treating surface water, groundwater, and municipal water with TDS up to 2,000 mg/L, this 8-inch element is ideal for packaged drinking water production, residential and community water supply systems, and food and beverage processing. Its energy-efficient operation makes it a cost-effective choice for municipal and industrial water treatment.
