Membrane filtration (reverse osmosis)

Removal of small molecules that pass through microfiltration and ultrafiltration membranes

Water flow from other processes (see combination with other technologies)

99% of organic matter and up to 99.5% of salts can be removed

In the case of manure treatment, the K+ ion still remains in the liquid fraction and could limit the use of the water obtained for irrigation depending on the levels reached;
Filtration systems usually suffer from technical problems and today are not economically viable for the treatment of matrices such as digestate;
