  • Patent number: 7172704
    Abstract: A method for treating waste water fluid, wherein the method comprises the steps of macerating waste water fluid in a first tank forming a sheared fluid, filtering the sheared fluid to remove solids, forming unfiltered waste water and product water, flowing product water to the first tank when the waste water fluid level is below the product water manifold, flowing the product water to a second tank when the waste water fluid level covers the product water manifold, flowing product water in the second tank into a vented loop to a third tank, diluting fluid in the third tank with raw water from a raw water source forming de-chlorinated water; and removing the de-chlorinated water from the third tank.
