초록 ▼

Provided is a standalone integrated water treatment system for a distributed water supply including a filter input, a coagulation system in operative connection with the filter input, wherein the water is subjected to a coagulation process to create pin floc from suspensions in the water. A maturation buffer tank in operative connection with the coagulation system aggregates floc in size within the water. A spiral separator separates the water 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 configured to receive the first stream of water and perform a filtration operation thereon. A sterilization system 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.

대표청구항 ▼

1. A method for treating water by use of a stand-alone integrated water treatment system the method comprising: filtering water provided to an input;performing a coagulation process, by a coagulation system, on water which has been filtered to remove material from the water, the coagulation system in operative connection with the input;generating floc of a prescribed size in the water, the water being held in a maturation buffer tank in operative connection with the coagulation system;separating the water into two water streams by operation of a spiral separator in operative connection with the maturation buffer tank, the two water streams including a first stream of water having a majority of the floc removed and a second stream of water including a concentrated amount of the floc, wherein the spiral separator is configured to separate floc of the prescribed size from the water;performing a sterilization operation, by a sterilization system, on the waters the sterilization system in operative connection with the spiral separator and configured to receive the first stream of water; andoutputting the water from the sterilization system as potable water;wherein at least one of a flow velocity or a pressure of the water flowing through the spiral separator, or a radius of curvature of a channel of the spiral separator, is adjusted such that the spiral separator separates floc of the prescribed size. 2. The system of claim 1 further including filtering the water of the first stream of water from the spiral separator before it has been sterilized, by a filtration arrangement in operative connection with the sterilization system. 3. The method of claim 1 including powering at least one of the coagulation system, the maturation buffer tank, the spiral separator, and the sterilization system by a solar power supply system. 4. The method of claim 1 wherein the coagulation system is an electrocoagulation system. 5. The method according to claim 1 wherein the spiral separator separates floc according to size. 6. The method according to claim 1 wherein all or part of the power needed to operate the water treatment unit is supplied by an integrated power supply.
