More Information
Summary:Several methods for recovering industrial process water are provided. The first method is a method for recovering industrial process water comprising injecting CO2 into industrial process water to produce a conditioned solution; and filtering the conditioned solution through a membrane filtration unit, producing a retentate solution and a permeate solution. Another method discloses filtering the industrial process water through a membrane filtration unit, creating a retentate solution and a permeate solution, and then routing the retentate solution to a precipitation tank, wherein supernatant water and precipitated solids are formed.
