Effluent weir system

1. An effluent weir system for a fluid treatment system having a separation tank, the effluent weir system comprising:

one or more effluent weirs mountable within the separation tank, each effluent weir extending from a first end to a second end, the effluent weir having an enclosed top portion and a continuous bottom inlet and a discharge in fluid communication with a clear well riser, each effluent weir bottom inlet extending from proximate the respective effluent weir first end to proximate the effluent weir second end;

a clear well in fluid communication with the separation tank through at least the one or more effluent weirs, the clear well defined by a bottom wall and enclosing side walls, each clear well side wall extending from a bottom portion connected to the clear well bottom wall to a top portion, the clear well further including a clear well discharge;

a clear well riser extending from a bottom portion in fluid communication with the effluent weir to a top end, the top end further comprising a clear well riser discharge;

each effluent weir further comprising:

an elongated pipe extending to a closed end within the separation tank, the pipe cross section comprising a diamond shape oriented with an apex on top.

2. The system of claim 1 , further comprising:

wherein the elongated pipe cross section is substantially square.

3. The system of claim 1 , further comprising:

wherein the interior cross section of the effluent weir extends beyond the interior cross section of clear well riser bottom portion.

4. The system of claim 1 , further comprising:

wherein the height of the clear well riser discharge within the clear well is adjustable.

5. The system of claim 4 , the adjustable height clear well riser further comprising:

each clear well riser further including an open top end;

a movable weir discharge member slidingly engagable over the clear well riser top end;

a first sealing member disposed between the clear well riser top end and the movable weir discharge member to seal therebetween; and,

a locking member selectively engagable between the movable weir discharge member and the clear well riser top end at user-selectable heights.

6. The system of claim 5 , the adjustable height clear well riser further comprising:

a second sealing member disposed between the clear well riser top end and the movable weir discharge member.

7. The system of claim 6 , further comprising:

the clear well riser top end further including a second exterior channel circumscribing the clear well riser proximate the clear well riser top end;

the second sealing member comprising a pliable ring insertable into the second exterior channel.

8. The system of claim 5 , further comprising:

the clear well riser top end further including a first exterior channel circumscribing the clear well riser proximate the clear well riser top end;

the first sealing member comprising a pliable ring insertable into the first exterior channel.

9. The system of claim 8 , further comprising:

the clear well riser top end further including a second exterior channel circumscribing the clear well riser proximate the clear well riser top end;

the second sealing member comprising a pliable ring insertable into the second exterior channel.

10. The system of claim 1 , further comprising:

a plurality of effluent weirs and a plurality of clear well risers, each effluent weir discharge in fluid communication with a corresponding clear well riser.

11. The system of claim 10 , wherein the height of each of the plurality of clear well riser discharges within the clear well is adjustable.

12. The system of claim 10 , each adjustable height clear well riser further comprising:

each clear well riser further including an open top end;

a movable weir discharge member slidingly engagable over the clear well riser top end;

a first sealing member disposed between the clear well riser top end and the movable weir discharge member to seal therebetween; and,

a locking member selectively engagable between the movable weir discharge member and the clear well riser top end at user-selectable heights.

13. The system of claim 12 , each adjustable height clear well riser further comprising:

a second sealing member disposed between the clear well riser top end and the movable weir discharge member.

14. The system of claim 12 , further comprising:

the clear well riser top end further including a first exterior channel circumscribing the clear well riser proximate the clear well riser top end;

the first scaling member comprising a pliable ring insertable into the first exterior channel.

15. An effluent weir system for a fluid treatment system having a separation tank, the effluent weir system comprising:

a receiving weir mountable within the separation tank, the receiving weir extending from a first end to a second end and including an enclosed top portion and a bottom inlet, the receiving weir further including first and second lateral sides, the respective receiving weir top portion and first and second lateral sides defining a diamond-shaped cross-section, the receiving weir bottom inlet extending from proximate the receiving weir first end to proximate the receiving weir second end;

a clear well in fluid communication with the separation tank through the receiving weir, the clear well defined by a bottom wall and enclosing side walls each clear well side wall extending from a bottom portion connected to the clear well bottom wall to a top portion, the clear well further including a clear well discharge;

one or more clear well risers extending from a respective riser bottom portion coupled to and in fluid communication with the receiving weir discharge to a respective riser discharge; and,

one or more effluent weirs mountable within the separation tank, each effluent weir having an enclosed top portion and first and second later sides extending downward from the enclosed top portion and defining a diamond-shaped cross-section, and a bottom inlet and extending from a first end to a second end, each second end coupled to and in fluid communication with the receiving weir, each effluent weir bottom inlet extending from proximate the respective effluent weir first end to proximate the respective effluent weir second end.

16. The system of claim 15 , further comprising:

the one or more clear well riser bottom portions coupled to the receiving weir along the receiving weir first lateral side and the one or more effluent weirs coupled to the receiving weir along the receiving weir second lateral side.

17. The system of claim 15 , further comprising:

wherein, the height of each of the plurality of clear well riser discharges within the clear well is adjustable.
