CSM (Composite-Separation-Membrane) membranes are a special type of membrane used for the separation of liquids or gases, often in industrial applications. These membranes perform separation processes by providing selective permeability between components with different chemical and physical properties.CSM membranes are generally produced from polymer materials and their mechanical strength is increased by supporting various techniques. Uses of such membranes include seawater desalination, food processing, pharmaceutical industry, chemical processes and wastewater treatment.The main advantages of CSM membranes include high separation efficiency, long life, chemical resistance and ability to operate in wide operating temperature ranges. These properties play an important role in increasing efficiency and supporting environmental sustainability in industrial processes.As a result, CSM membranes are a critical technology for many industrial applications where separation of different components is required and are constantly being developed and improved.
