Water treatment through nano-filtration process

Nano-filtration process is mainly used to remove the bivalent ions contained in water and to remove partially, any traces of nitrate and other mineral salts present.

It is a Reverse Osmosis process that envisages the use of membranes less selective to the Salts. The advantage is that they require a much lower working pressure.

At the same time it also plays a very important role in water sterilisation.
