Stand-alone integrated water treatment system for distributed water supply to small communities

摘要

Provided is a standalone integrated water treatment system for a distributed water supply. A filter input receives water to be treated. A coagulation system is in operative connection with the filter input, wherein the water which has been filtered is subjected to a coagulation process performed by the coagulation system to create pin floc from suspensions in the water. A maturation buffer tank is in operative connection with the coagulation system, wherein floc is aggregated in size within the water. A spiral separator is in operative connection with the maturation buffer tank, and the water is separated into two water streams, a first stream of water having most of the floc removed, and a second stream of water which includes a concentrated amount of the floc. An optional filtration system is in operative connection with the spiral separator and is configured to receive the first stream of water and to perform a filtration operation on the first stream of water. A sterilization system is in operative connection with the optional filtration system and is configured to perform a sterilization operation on the first stream of water. The water is then output from the sterilization system as potable water.
