Ultrafiltration process scheme

Ultrafiltration process scheme

The biomass in excess forms the biological reactors (biological earthenware), once out of the reactors, are introduced in a ultrafiltration process. The objective of this process is to separate the biomass of the depurated liquid by means of low pressure semi permeable membranes, with a biomass and insoluble impurities retention capacity of 0.02 µm.

The decanted earthenware of the biological reactors waters are pumped in the ultrafiltration proces at a speed so high that avoids the matter accumulation in the membranes surfaces, fact that reduces the cleaning maintenance cost of the filters.

After this treatment the water is gathered in a intermediate deposit before passing to the following nanofiltration phase, while the mud exceeding is retained and stored to be evacuated outwards.
