Product Description

Ultrafiltration membranes are characterized by their molecular weight cut-off between 1,000-200,000 Dalton usually. Ultrafiltration is a pressure-driven membrane process being capable of separating solution components on the basis of molecular size and shape. Under an applied pressure difference across an ultrafiltration membrane, solvent and small solute species pass through the membrane and are collected as permeate while larger solute species are retained by the membrane and recovered as a concentrated retentate.
Our acid and caustic resistant membrane can be used for high concentrate solution.
pH is available for 0-13.


RisingSun Membrane located in Beijing China is a very successful manufacturer for a wide range of polymeric industrial spiral wound UF membranes, standard size 2540/4040/8040, which can be used for research and industrial process applications. Also, we can use different size feed spacer to meet different liquid requests. We use automitic rolling machine to keep the high quality.

UF Products
We offer an extensive range of ultrafiltration molecular weight cut-offs available in both flat sheet and spiral-wound configurations. These are suitable for use in both sanitary and industrial-grade applications. Sanitary membranes meet compliance with FDA standards listed in CFR Title 21,which can be used for food and dairy industry.

After years of research and development, We can offer a wide range of MWCO and membrane chemical to meet different filtration requests.
To meet some specialty applications, acid/caustic resistant, fouling resistant or high temperature membrane products are available.
