Patent Modified Acid & High Pressure Resistant Industrial RO Membrane
Product Description
-
Membrane Sheet Material: Thin-film composite aromatic polyamide membrane
-
Core Membrane Properties: Acid corrosion resistant, high operating pressure compatible
-
Outer Casing: High-strength fiberglass reinforced plastic (FRP)
-
Flow Channel Specification: 34mil / 46mil open parallel flow paths, with optional custom sizes
-
Target Use Cases: Acid recovery from power plant industrial wastewater, lithium iron phosphate production lines, and separation, purification, fractionation and concentration workflows for various acidic feedstock systems
Product Features
-
Built with top-tier imported base membrane sheets empowered by our in-house patented modification technology, which eliminates micro-scale structural flaws on the membrane surface, and achieves a well-balanced performance across acid resistance, permeate flux and salt rejection
-
Delivers industry-leading acid tolerance: it can safely concentrate phosphoric acid up to 15% by weight, and both hydrochloric acid and sulfuric acid up to 10% by weight at maximum
-
Every single structural component of the membrane element is engineered to maintain long-term stability under continuous low pH operation
-
The custom-formulated high-strength sealing compound drastically reduces acid seepage at the membrane element's sealing interface under sustained high pressure, and significantly improves the overall contaminant retention efficiency
