The separation membrane "Separation Membrane Digest" introduces "FILMTEC Reverse Osmosis Membrane (RO Membrane)", "FILMTEC Nanofiltration Membrane (NF Membrane)", and "Desal Exclusion Filtration Membrane (UF Membrane)". Separation membranes are used in various fields such as purification → removal of impurities (removal of suspended solids, bacteria, and ions in water), concentration → production of table salt from seawater (ion exchange membrane electrodialysis), and separation → bio and pharmaceutical applications (separating low and high molecular weight substances). This is the comprehensive catalog of separation membranes from Muromachi Chemical Co., Ltd., which offers recommendations for selecting and combining membranes according to their types and applications. For more details, please download the catalog.

FILMTEC reverse osmosis membrane (RO membrane) "Filmtec Membrane" has recently been applied not only to pure water production but also to wastewater treatment, purification of pharmaceuticals and food, separation of active ingredients, and many other applications such as seawater desalination. Therefore, we are focusing on the development of next-generation separation technologies by applying the separation techniques cultivated with ion exchange resins to membrane separation using Filmtec Membranes, which come in many grades. For more details, please download the catalog.

FILMTEC nanofiltration membrane (NF membrane) "NF Series" is also known as loose RO and is primarily aimed at the removal of divalent ions. It is used in the production of drinking water, various raw water, wastewater treatment, and various processes. It is the same as RO membrane. For more details, please download the catalog.

The ultrafiltration membrane (UF membrane) "Desarl" is a spiral-shaped UF membrane. Its shape is identical to that of reverse osmosis membranes (RO membranes). The price per unit area is lower compared to hollow fiber membranes. It enables separation in a relatively small molecular weight range compared to conventional ultrafiltration membranes (UF membranes). It is used not only for the separation of target and non-target substances in various processes but also for wastewater treatment and pure water processing. For more details, please download the catalog.

When membranes are used for a long time, they gradually become clogged, leading to a decrease in permeate flow rate. Chemical cleaning with agents can restore the filtration performance of various clogged separation membranes (RO membranes, UF membranes, NF membranes, MF membranes). Cleaning can be performed regardless of the type of membrane, and repairs can also be made to the leak points of hollow fiber membranes. We will confirm and report the permeate flow rate and desalination performance before and after cleaning. 【Recommended for the following concerns】 ■ I want to try cleaning separation membranes. ■ I want to review costs because the current outsourcing costs are high. ■ I want to repair leak points. ■ Separation membranes clog up quickly. ■ The cost of blow cleaning new separation membranes is high. *For more details, please refer to the PDF document or feel free to contact us.
