Patent ID: 7172704

Claim:
A method for treating waste water fluid, wherein the method comprises the steps of: a. macerating waste water fluid in a first tank forming a sheared fluid; b. filtering the sheared fluid to remove solids by separating the waste water into two streams forming unfiltered waste water and product water using a cross-flow filter; c. returning the unfiltered waste water to the first tank; d. flowing product water to the first tank when the waste water fluid level is below a product water manifold; e. flowing the product water to a second tank when the waste water fluid level covers the product water manifold; f. flowing product water in the second tank into a vented loop to a third tank, and upon demand, draining the second tank of product water, and upon demand, macerating the product water of the second tank prior to flowing the product water into the vented loop; g. adding a de-chlorinating agent to the third tank and diluting fluid in the third tank with raw water from a raw water source forming de-chlorinated water; and h. removing the de-chlorinated water from the third tank.
