Water treating apparatus

Claim 2

THE WATER TREATING APPARATUS COMPRISING: A TANK; A PARTITION WITHIN SAID TANK DEFINING A SETTLING ZONE; MEANS FOR REMOVING TREATED WATER FROM SAID SETTLING ZONE; AN UPTAKE MEMBER WITHIN SAID PARTITION DEFINING A MIXING AND RECIRCULATION ZONE, SAID UPTAKE MEMBER INCLUDING A LOWER OPENING; A PLURALITY OF UPWARDLY DIRECTED NOZZLES CONNECTED TO AN INTAKE MEANS, SAID NOZZLES BEING DISPOSED WITHIN SAID UPTAKE MEMBER AND WITHIN THE PERIMETER OF SAID LOWER OPENING IN SAID UPTAKE MEMBER; AND PERCIPITATE COLLECTING MEANS UNDERLYING SAID LOWER OPENING WHEREBY PRECIPITATES FROM SAID COLLECTING MEANS ARE MIXED WITH LIQUID PASSING THROUGH SAID NOZZLES IN SAID UPTAKE MEMBER AND ARE PASSED INTO SAID MIXING AND RECIRCULATION ZONE.

Claim 3

The apparatus set forth in claim 1 further comprising a rotatable rake disposed at the bottom of said tank for moving precipitates to said collecting means and means for removing said precipitates from said collecting means.

Claim 4

The water treating apparatus comprising: a tank; a partition within said tank defining a settling zone; an uptake member within said partition defining a mixing and recirculation zone, said uptake member including a lower opening; a plurality of upwardly directed nozzles connected to an intake means, said nozzles being disposed within said uptake member and within the perimeter of said lower opening in said uptake member; precipitate collecting means underlying said lower opening whereby precipitates from said collecting means are mixed with liquid passing through said nozzles in said uptake member and are passed into said mixing and recirculation zone; a flow control chamber; a flow control inlet conduit communicating with said intake means and said flow control chamber; a flow control outlet conduit communicating with said flow control chamber at a plurality of apertures in said uptake member.

Claim 5

The water treating apparatus comprising: a tank; a partition within said tank defining a settling zone; an uptake member within said partition defining a mixing and recirculation zone, said uptake member including a lower opening; a plurality of upwardly directed nozzles connected to an intake means, said nozzles being disposed within said uptake member and within the perimeter of said lower opening in said uptake member; precipitate collecting means underlying said lower opening whereby precipitates from said collecting means are mixed with liquid passing through said nozzles in said uptake member and are passed into said mixing and recirculation zone; a flow control chamber; a flow control inlet conduit communicating with said intake means and said flow control chamber; a flow control outlet conduit communicating with said flow control chamber at a plurality of apertures in said uptake member.

Claim 6

The apparatus set forth in claim 3 wherein said flow control outlet conduit communicates with an annular distribution chamber disposed around the apertured portion of said uptake member.

Claim 7

The apparatus set forth in claim 4 further comprising a rotatable rake disposed at the bottom of said tank for moving precipitates to said collecting means and means for remoVing said precipitates from said collecting means.

Claim 8

The water treating apparatus comprising: a tank; a partition within said tank defining a settling zone; means for removing treated water from said settling zone; an uptake member within said partition defining a mixing and recirculation zone, said uptake member including a lower opening, a medial uptake zone and an upper preliminary mixing zone; baffle means disposed in said preliminary mixing zone; a plurality of upwardly directed nozzles connected to an intake means, said nozzles being disposed within said uptake member and within the perimeter of said lower opening in said uptake member; precipitate collecting means underlying said lower opening whereby precipitates from said collecting means are mixed with liquid passing through said nozzles in said uptake member and are passed through said preliminary mixing zone into said mixing and recirculation zone.

Claim 9

The water treating apparatus comprising: a tank; a partition within said tank defining a settling zone; means for removing treated water from said settling zone; an uptake member within said partition defining a mixing and recirculation zone, said uptake member including a lower opening, a medial uptake zone and an upper preliminary mixing zone; baffle means disposed in said preliminary mixing zone; a plurality of upwardly directed nozzles connected to an intake means, said nozzles being disposed within said uptake member and within the perimeter of said lower opening in said uptake member; precipitate collecting means underlying said lower opening whereby precipitates from said collecting means are mixed with liquid passing through said nozzles in said uptake member and are passed through said preliminary mixing zone into said mixing and recirculation zone.

Claim 10

The apparatus set forth in claim 6 wherein said baffle means comprises an annular baffle disposed at the top of said uptake member.

Claim 11

The apparatus set forth in claim 6 wherein said baffle means comprises a horizontal disc-like baffle disposed within said preliminary mixing zone.

Claim 12

The apparatus set forth in claim 6 wherein said baffle means comprises a horizontal disc-like baffle disposed within said preliminary mixing zone and an annular baffle disposed at the top of said uptake member.

Claim 13

The apparatus set forth in claim 9 further comprising a rotatable rake disposed at the bottom of said tank for moving precipitates to said collecting means and means for removing said precipitates from said collecting means.
