Title: Sewage sludge decontamination - forces sludge by centrifugal force against cathode wall, ionises heavy metals for deposition on anode
Inventor: REIMANN HANNO
IPC: C02F11/00
Filed: 1991-12-16
Abstract: To decontaminate sewage sludge etc., for recycling as soil improvers and fertilisers, the sludge is forced against a cathode wall by centrifugal force, while the heavy metals are ionised and deposited on the anode. The anode is pref. protected from ballast material by a shield. The chemical reactions to degrade the toxic matter in the sludge are enhanced and/or supported while and during the electrolysis. The character of the sludge is set chemically to give a required electrical conductivity, pH value and chemical ion excitation. USE/ADVANTAGE - For processing residual sludge and the like from the cleaning basins for domestic and industrial sewage. Any heavy metals and toxic matter are effectively removed from the sludge for disposal without damage to the environment, leaving processed material which can be returned to the natural environmental cycle.
