| Filtration Types |
| Depending on their performance characteristics, particularly their nominal pore sizes, membranes used in filtration devices are placed in one of four categories: Microfiltration, Ultrafiltration, Nanofiltration or Reverse Osmosis. |

| Configurations |
Membranes can be made up of different configurations namely, Hollow Fibre, Tubular, Spiral Wound, and Flat Sheet.
Membranes are configured differently to obtain the maximum exchange surface per unit volume, limit the circulation polarization, and the particle deposits by providing a sufficient flow of treated liquid.

| Materials |
| Membranes can be produced from all kinds of different materials. Each material has its own advantages and disadvantages when applied to certain processes. Here are some of the widely-used materials: Polymeric, Ceramic, Stainless Steel, and Polyolefin. |
