Acid-Resistant High-Pressure Reverse Osmosis Membrane Products
Product Description
- Membrane material: aromatic polyamide composite membrane
- Membrane characteristics: acid resistance, high pressure resistance
- Outer wrapping type: fiberglass
- Flow channel type: Parallel flow channel 34 mil/46 mil, etc.
- Application scenarios: acid recovery from power plant wastewater, iron phosphate projects, separation, purification, and concentration of acid-containing materials, etc.
Product Features
- Using imported membrane sheets combined with its own modified patent, the micro defects on the surface of the membrane are eliminated to improve the acid resistance and the balance between flux and desalination rate;
- Excellent acid resistance: phosphoric acid concentration up to 15%, hydrochloric acid and sulfuric acid concentration up to 10%.
- All structural materials can withstand low pH values;
- The use of multi-page/short page welding increases the effective area utilization rate and improves the water production efficiency;
- The special adhesive seal is used to reduce the permeability of acid liquid at the sealing part of the membrane element under high pressure and improve the overall retention performance.
