Title: Treatment of water
Inventor: TANGO HIDEHIRO
IPC: B03B5/28
Filed: 1984-12-24
Abstract: PURPOSE:To separate and remove ashes having comparatively small grain size effectively by adding water to slurry contg. activated carbon treated by wet type oxidation and the ashes having comparatively small grain size to dilute the slurry, performing isolation of the activated carbon and the ashes granules and allowing the activated carbon to settle. CONSTITUTION:In water treatment wherein waste water or the like are brought into contact with activated carbon, the activated carbon discharged from water treatment apparatus in which the activated carbon is used is regenerated by a wet type oxidation. By adding water to slurry contg. the activated carbon treated by the wet type oxidation and ashes which has comparatively small grain size and performing dilution operation, interfacial dynamic electric potential of the ashes granules is increased and the isolation of the activated carbon and the ashes granules is performed to allow the activated carbon to settle and to separate and remove the ashes. The settle activated carbon is reintroduced to said water treatment apparatus. By this method, the ashes having comparatively small grain size can be separated and removed effectively. Since only water is used to separate and remove the ashes, said method is performed inexpensively. Furthermore, it can be prevented that the purified water becomes slightly opaque due to transferring of the ashes into said water in the water treatment.
