Patent ID: 7022240

Claim:
A mobile water treatment process for use in treating waste fluids from oil and gas well drilling operations in a fluid waste collection area at the site of such operations, said processing comprising: a. pumping said waste fluids from said collection area, through a mobile treatment apparatus and back into said collection area; b. adding an alkaline agent to said waste fluids as said waste fluids are pumped through the mobile treatment apparatus in an amount necessary to bring the pH of said waste fluids to a range of about 9.0 to 12.0 before return to said collection area and also sufficient to cause soluble contaminants in the waste fluids to form a precipitate; c. allowing said waste fluids to clarify as said precipitate of soluble contaminants, through flocculation, settle and form a sludge at the bottom of said collection area; d. filtering said waste fluids in said mobile water treatment apparatus after said clarification step; and e. pumping said waste fluids, after said filtration step, into storage tanks for reuse at future drilling operations.
