Abstract
The invention relates to a system, process and apparatus for separating biosorbent and sorbate. Biomass enclosed within a membrane system is coupled to an electrode, which is capable of being placed in contact with the sorbate containing material in the presence of a counter electrode. An electric field may be discharged across the electrodes and ionic species will migrate into the membrane enclosed system. The migrated species within the membrane can be taken up and processed by the biosorbtive processes of the biomass. The system may be used to remove dye stuffs, metal, heavy metals, radionuclides and other pollutants from natural and artificial sources.
