Huamo TF22-4040FR Fouling-Resistant RO Membrane Element
The TF22-4040FR fouling-resistant aromatic polyamide composite RO membrane delivers up to 99.5% salt rejection with enhanced anti-fouling performance. Specifically designed for challenging feed water conditions, it resists organic and biological fouling, making it ideal for wastewater reuse, surface water treatment, and industrial water recycling applications.
- Low energy consumption
- High filtration accuracy
- Large water output
- Strong anti-fouling
Product Introduction
The TF22-4040FR is a fouling-resistant aromatic polyamide composite reverse osmosis membrane element developed by Huamo Environmental. Featuring a specially designed feed spacer and membrane surface that resists organic and biological fouling, it achieves a stable salt rejection rate of up to 99.5% with a minimum rejection of 99.0% while maintaining consistent permeate output. The anti-fouling design reduces cleaning frequency and extends membrane service life, making it particularly effective for feed water sources prone to biological or organic contamination. It is widely applied in wastewater reuse, surface water treatment, industrial water recycling, and municipal drinking water production with TDS up to 5,000 mg/L.
