plant fig2 is an embodiment in accordance with principals of the invention of fig1 the diverted raw wastewater 107 flows through the inlet pipe 109 to a feed pump 201 the feed pump 201 supplies a cyclone or vortex separator 203 post feed pump wastewater 205 through feed pipe 207 the feed pump 201 may be any pump capable of being controlled with a variable rate of flow and capable of supplying net positive suction pressure to the vortex separator 203 for example in one embodiment the feed pump 201 is a centrifugal feed pump in another embodiment the feed pump 201 is a centrifugal grinder pump a grinder pump takes larger solid objects for example rags condoms tampons or sanitary napkins grinds or macerates them into smaller particulates in another embodiment the feed pump 201 and vortex separator 203 may be combined into one unit that performs the function of both feed pump and vortex separator in fig2 the vortex separator 203 takes the post feed pump wastewater 205 and separates it into concentrated solids 117 that flow through the second outlet pipe 119 and separated liquid 113 that flows through the outlet pipe 115 the vortex separator 203 uses centrifugal force to spin the wastewater forcing the heavier materials to the outside periphery of a containment pipe the separated liquid 113 which is mostly water with a lower specific gravity lighter stays to the center of the containment pipe as the solution is flowing downstream in the containment pipe the concentrated solids exit at the periphery of the containment pipe through the second outlet pipe 119 while the mostly water or separated liquid 113 is drawn off of the center of the end of the containment pipe though the.
