Abstract
A system and method for removing contaminates from greywater that uses carbon dioxide (CO2) and a system that adjusts the pH between 6 and 9. The filtration system is cost effective, quick, and easy to use, resulting in purified water.
Claims3
A system for the purification of greywater comprising:
- a) a large, suspended particle filter that filters particles greater or equal than 10 microns in the greywater;
- b) a fines suspended particle filter that filters particles less than 10 microns in the greywater;
- c) a CO2 source;
- d) a first bubbling chamber which is designed to receive CO2 from the CO2 source and greywater which has been treated to remove the suspended particles, wherein the first bubbling chamber can bubble CO2 through the greywater until the greywater reaches about 6.4 pH;
- e) a pressure chamber to add the about 6.4 pH greywater and keep a pressure of from about between 1 and 10 psig until the dissolved particles become suspended particles;
- and
- f) a particle filter to filter any suspended particles resulting from the pressure treatment of the greywater.

A method for the treatment of greywater comprising:
- a) filtering the greywater with one or more particle filters to remove all suspended solids in the greywater;
- b) adding the filtered greywater to a CO2 bubbling chamber;
- c) using a first single pass bubbling CO2 into the bubbling chamber until the filtered greywater is saturated with CO2 to a pH of about 6.4 prior to entering a pressure chamber;
- d) transferring the about 6.4 pH greywater to the pressure chamber at a pressure of from about 1 to 10 psig until dissolved solids become suspended solids;
- e) transferring the pressure treated greywater and the suspended solids to a second bubbling chamber and bubbling CO2 through the pressure treated greywater;
- and
- f) filtering the pressure treated and CO2 bubbled greywater through a small fines filter.
