Product Introduction
The TF31-8040 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 stable salt rejection rate of 99.4% or higher with a minimum rejection of 99.0%, delivering excellent permeate output 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 reduces overall system operating costs.
