Processing of the liquid fraction
Membrane filtration (Microfiltration, ultrafiltration)
Objective
Microfiltration:Removal of suspended solids, bacteria and viruses (particles in the range of 0.1 - 10 µm).Ultrafiltration:Separation of suspended solids, bacteria and viruses between 0.04 -0.1 µm.
Inlets
Water flow from other processes (see combination with other technologies)
Efficiency
99% of organic matter and up to 99.5% of salts can be removed
Weaknesses
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;
