A well-arranged process conduction which infact work without the addition of chemicals. Membrane technology is a generic term for separation processes. With membrane filters, filtration mainly occurs on the filter surface. Particles, which are larger than the normal pore size, remain on the filter, smaller particles pass through it unless other interactions gets retained in them.

 They are used to separate colloids, Suspended particles and molecules from liquids. Thus feed flow is divided into two streams a filtrate stream, and a highly concentrate stream.

Membrane systems with its filtration can be managed in either dead-end flow or cross-flow. The purpose of the optimization of the membrane techniques is the achievement, which is of the highest possible production for a long period of time, with acceptable pollution levels.
