Abstract
A mixing spool is utilized to mix a liquid coagulant into water flowing through a large conduit. The mixing spool is inserted as a segment into the conduit. The mixing spool utilizes a pair of opposite facing nozzles which extend through a wall of the spool into the interior of the spool. The nozzles receive a pressurized liquid flow through a manifold. A chemical injection quill has an open end positioned between the opposite facing nozzles, wherein the chemical injection quill is configured to deliver the liquid coagulant into the water flowing through the conduit.

A method of mixing a liquid coagulant into a flowing volume of water in a piping conduit, the piping conduit having an outside diameter ranging from 16 inches to 94 inches, the method comprising the steps of:
- directing the flowing volume of water flowing through a pipe spool which has been preinstalled as an integral component of the piping conduit, the pipe spool comprising an integral conduit portion comprising a length extending between an upstream end and a downstream end, the pipe spool further comprising a first manifold comprising a first upstream distal end, the first upstream distal end comprising a first upstream nozzle which extends into an interior of the integral conduit portion, the pipe spool further comprising a second manifold comprising a second upstream distal end, the second upstream distal end comprising a second upstream nozzle which extends into the interior of the integral conduit portion, wherein the second upstream nozzle is disposed diametrically opposite the first upstream nozzle, wherein the first upstream nozzle and the second upstream nozzle are disposed at a first axial position along the length;
- delivering a pressurized flow of water into an inlet, wherein the pressurized flow of water is directed from the inlet to the first upstream nozzle and to the second upstream nozzle;
- and
- injecting the liquid coagulant into a chemical injection quill, the chemical injection quill having an end which extends into the interior of the integral conduit portion and into the flowing volume of water resulting in a treated flow of water, the end disposed at a position between the first upstream nozzle and the second upstream nozzle.
A method of mixing a liquid coagulant into a flowing volume of water in a piping conduit at a first flow rate, the piping conduit having an outside diameter ranging from 16 inches to 94 inches, the method comprising the steps of:
- directing the volume of water flowing through the piping conduit through a pipe spool which has been preinstalled as an integral component of the piping conduit, the pipe spool comprising a first nozzle which extends into an interior of the pipe spool and the pipe spool comprising a second nozzle which extends into the interior of the pipe spool, wherein the first nozzle and the second nozzle are in opposite facing relation;
- delivering a pressurized flow of water through the first nozzle and the second nozzle;
- and
- injecting the liquid coagulant into a chemical injection quill, at a second flow rate, the chemical injection quill comprising an end disposed between the first nozzle and the second nozzle, the chemical injection quill configured to deliver the liquid coagulant into the volume of water flowing resulting in a treated flow of water, wherein the second flow rate ranges from 0.0003 percent to 0.01 percent of the first flow rate.
A method of mixing a liquid coagulant into a volume of water flowing through a piping conduit at a first flow rate, the piping conduit having an outside diameter ranging from 16 inches to 94 inches, the method comprising the steps of:
- diverting a portion of the volume of water flowing through the piping conduit into a manifold assembly, resulting in a mainstream flow of water in the piping conduit and a diversion flow of water in the manifold assembly;
- directing the mainstream flow of water in the piping conduit flowing in the piping conduit through a pipe spool which has been preinstalled as an integral component of the piping conduit, the pipe spool comprising a first nozzle which extends into an interior of the pipe spool and the pipe spool comprising a second nozzle which extends into the interior of the pipe spool, wherein the first nozzle and the second nozzle are in opposite facing relation;
- directing the diversion flow of water into the first nozzle and the second nozzle;
- and;
- injecting the liquid coagulant into a chemical injection quill, at a second flow rate, resulting in a treated flow of water, wherein the second flow rate ranges from 0.0003 percent to 0.01 percent of the first flow rate, the chemical injection quill having an end which extends into the interior of the pipe spool, the end disposed at a position between the first nozzle end and the second nozzle.
