Abstract
1382161 Purifying sewage NORM AMC AG 20 Jan 1972 [21 Jan 1971] 2743/72 Heading C1C In a process for purifying sewage, e.g. removing phosphates, the sewage together with a flocculating or precipitating agent from conduit 13, is passed through conduit 10 to mixing zone 5 of tank 1 containing gyroscopic mixer 11 and the mixture is passed downwardly through flocculation zone 6 by helical screw 14, to sedimentation zone 3 where the sludge settles out from the purified water which is discharged from clear water zone 8 over weir 15. Some sludge may be recycled from zone 3 to zone 5 through pipe 16 by the suction of mixer 11. Sludge may be periodically discharged from zone 3 under the control of photoelectric means. The tank 1 may be substantially cone- or pyramid-shaped.
[GB1382161A]
Claims (1)
1. 5 A process according to of Claims 1 to wherein of the sedimented sludge particles are returned to the mixing zone by means of the suction produced in the mixing unit as a result of the rotating movement of the A process according to Claim wherein the mixture of sewage and precipitating agent is conducted along a spiral path by means of inserts provided in the flocculatlon An carrying out the process according to Claim 1 comprising at least conduit for supplying the sewage and the precipitating agent into a mixing zone situated in the upper region of a compartment of a a mixer for intimately mixing of the sewage and the precipitating agent in this mixing wherein the basin divided by a wall located therein and extending upwardly above the water level present during operation and downwardly into the sedimentation and by a layer of thickened sludge raising beyond the lower edge of that partition wall into a first compartment containing the mixing zone and flocculation zone and a second compartment constituting the clear water zone which can communicate with the first zone only through the sedimentation Apparatus according to Claim 6 wherein the basin is separated by the partition wall a central compartment containing the mixing zone and flocculating zone and a second compartment surrounding the first and containing the clear water 16 An apparatus according to Claim wherein the basin has a conical or shape with the wider cross section facing and partition wall extends into the bottom or lateral wall portion of the apparatus according to Claim wherein the basin has a pyrimidal or truncated pyrimidal shape with upwardly extending increasing cross An apparatus according to Claim wherein at least one riser extending from the mixing zone into the sedimentation zone is provided for returning part of the settled out flocculated sludge from the sedimentation to the mixing An apparatus according to Claim wherein the mixing unit consists of a rotor situated immediately below the water level and suction side connected with the A apparatus accordin to one or more of Claims 6 to wherein the supply conduit o the sewage water is connected with the supply conduit of the precipitation agent before its connection with the aspiration side of the mixing An apparatus according to one or more of Claims 6 to wherein the flocculatlon zone i provided with inserts designed in such a manne as to cause a shaped movement of the mixture consisting of the sewage 17 and precipitating agent during the through the flocculation For the Applicants insufficientOCRQuality
