Membranes, in general, are selective barriers available in different shapes and sizes for separating gases or liquids based on different factors.
A composite membrane refers to a membrane composed of two or more layers or materials that have distinctive roles in separation. It can be of organic-inorganic moiety or inorganic-inorganic moiety like polymer-metalllic membrane, ceramic-polymeric membrane, mixed matrix membrane etc.
In Nordische, we generally deal into polymer based composite membrane, say, ceramic or zeolite or dense or other porous membranes on a support. This has a wide range of applications from gas separation, desalination, wastewater treatment, water, purification, metal extraction, storage and sequestration etc.
These are available in different sizes and shapes.
