Abstract:
1. A stand-alone integrated water treatment system for distributed water supply comprising: a filtered input for receiving and treating water; a coagulation system in operative connection with the filtered input, wherein the water which has been filtered is processed by a coagulation process by the coagulation system to create pin floc suspensions in the water; a maturation buffer tank in operative connection with the coagulation system, wherein the pin floc is aggregated to a larger size in the water; a planar spiral separator having a curved channel comprising side walls and top and bottom walls perpendicular to the side walls, the curved channel being in operative connection with the maturation buffer tank, wherein the water is separated into two water streams a first stream of water having a majority of the floc removed and a second stream of water which includes a concentrated amount of the floc, wherein separation within the channel is based on the curvature of the channel in combination with at least one of velocity and pressure profiles within the channel, or hydrodynamic forces within the channel; a sterilization system in operative connection with the spiral separator and configured to receive the first stream of water and to perform a sterilization operation on the first stream of water; an output for outputting the water from the sterilization system as potable water; and at least one power supply for providing power to the stand-alone integrated water-treatment system.
