ABSTRACT:
Aqueous sewage is conducted in series through two filter beds with which the sewage reacts within settling tanks. The tanks are charged with particulate coke formed from the coking of a high sulphur coal with steam. The gaseous products of the coking operation are fed to one of the settling tanks within which an electric field is established to electrically charge the filter bed.
