Abstract:
1. A method for fluid filtration and remediation, wherein the method comprises: a. introducing an initial slurry into a filtration system scalping shaker, wherein first filtration particulates are removed from the initial slurry forming a first filter effluent; b. passing the first filter effluent into a first tank in communication with a second tank, wherein the first filter effluent is pumped from the first tank to the second tank; c. removing free oil from the first filter effluent forming a cleaned effluent; d. using hydrostatic pressure in the second tank to pass the cleaned effluent to a circulation component; e. passing the cleaned effluent through a series of absorbent materials forming a circulation effluent wherein the series of absorbent materials are a recyclable hydrocarbon absorbent material comprising a plurality of pillow shaped materials that are squeezable for removing absorbed hydrocarbons; f. depositing the circulation effluent into a circulation tank and settling sludge out of the circulation effluent; g. passing the circulation effluent through a discharge pump, wherein the discharge pump comprises an inlet in fluid communication with the circulation tank and an outlet in fluid communication with an inlet of a filtration membrane; h. separating the circulation effluent into a clean permeate and a dirty concentrate; i. discharging the dirty concentrate from the filtration membrane and reintroducing the dirty concentrate into the circulation tank, wherein the introduction of the dirty concentrate into the circulation tank circulates circulation effluent in the circulation tank; j. discharging the clean permeate from the filtration membrane to an end use; and k. applying pressure to the series of absorbent materials to remove the free oil therefrom.
