High-Purity Sanitary RO Membrane for Separation & Concentration
Product Description
-
Outer Encapsulation: Sanitary-grade stainless steel cage housing
-
Feed Spacer Configuration: 32mil / 34mil parallel flow spacers, with other custom sizes available upon request
-
Application Coverage: Separation, purification, decolorization, desalination and concentration of various process materials and feed streams
Product Features
-
Membrane Technology: Utilizes premium imported membrane sheets integrated with our proprietary modification patent, which eliminates micro-scale surface defects, enhances anti-fouling performance, increases permeate flux, and optimizes salt rejection. Membrane type (UF/NF/RO) can be selected based on pilot-scale test results.
-
Structural Integrity: Features a seamless external cage hot-welded construction, eliminating internal dead zones and minimizing stagnant water areas for enhanced hygiene.
-
Sealing Excellence: Incorporates a specially formulated adhesive sealant that effectively reduces material loss during operation, ensuring optimal process yield.
