Process and apparatus for removal of biocolloids from water

Biocolloids, e.g. Cryptosporidium parvum oocysts, are removed from water by filtration using a packed bed of a granular filter medium, preferably MgO, establishing an electric field across the packed bed, perpendicular to the flow of the water through the packed bed. The packed bed is provided in an annular space between two concentric electrodes.
