Abstract A method of purifying waste water comprises carrying out an electrolysis of water in a defined area of a vessel in order to form oxygen and hydrogen therein and directing a flow of the waste water into the electrolysis area to subject the waste water to the influence of the newly formed oxygen and hydrogen to cause promotion of nuclei formation to cause a bonding coagulation of the waste material around the nuclei. A device for carrying out the invention includes a vessel for the water to be purified having an inner wall with an overflow for the water and for flocculated waste which is directed into a separating chamber for the removal of the solid waste material. The vessel includes a central tubular conduit having spaced electrodes which are subjected to a DC potential in order to produce an electrolysis in the area and the production of oxygen and hydrogen. The waste water is then circulated into the conduit in the electrolysis area and the contact with the hydrogen and oxygen causes the promotion of the formation of nuclei which produces the coagulation of the waste material. The newly coagulated waste material and the remaining liquid is then discharged into the liquid of the vessel and permitted to float to the top which includes an overflow portion for the separation of the purified liquid from the flocculated material. The vessel itself includes a filter at its bottom for the passage of the filtered liquid therethrough after the liquid has passed through the tube and is subjected to the hydrolysis effect to aid in the removal of the solid waste materials therefrom.
A METHOD OF TREATING WASTE WATER SLUDGE IN A VESSEL HAVING AN OUTER CONTAINER AND AN INNER TUBULAR MEMBER OF MUCH SMALLER OUTER DIAMTER THAN SAID OUTER CONTAINER EXTENDING UPWARDLY THROUGH THE INTERIOR OF THE OUTER CONTAINER AND HAVING SPACED APART RESPECTIVE POSITIVE AND NEGATIVE ELECTRICAL TERMINALS THEREIN AT AN ELECTRICAL POTENTIAL, COMPRISING DIRECTING A SLUDGE WAST FLOW TO BE TREATED INTO THE LOWER END OF THE INNER TUBULAR MEMBER AND A QUANTITY OF ELECTROLYTE IN ORDER TO PRODUCE AN ELECTROLYTIC ACTION ADJACENT SAID TERMINALS IN A QUANTITY AND RATE TO CAUSE THE SLUDGE WASTE TO PRODUCE FLOCCULATION OF THE MATERIAL, FURTHER DIRECTING A PLURALITY OF PARTIAL FLOWS OF SLUDGE WASTE FLOW WITH THE FLOCCULANTS ALREADY PRODUCED UPWARDLY AND TANGENTIALLY INTO THE OUTER CONTAINER TO MAINTAIN THE WATER LEVEL IN THE OUTER CONTAINER TO CAUSE OVERFLOW THEREOF, MIXING THE PARTIAL FLOWS TO PROMOTE FLOCCULATION REACTION IN THE OUTER CONTAINER TO FORM THE FLOCCULATING MATERIALS INTO A BALL SIZE SLUDGE AND PASSING AT LEAST A PORTION OF THE OVERFLOW THROUGH A SCREEN TO SEPARATE THE LIQUID FROM THE SOLID FLOCCULATIONS, AND COLLECTING THE FLOCCULATIONS FROM THE SCREEN.

Claim 3
Dependent Claim
