Abstract: Defluidizing tanks may include a tank having an interior defined by side walls and a bottom; a filter assembly emplaced within the interior of the tank and constructed to receive a slurry of solids and recovered fluid; and a weir chamber within the tank and defined by the interior of the tank and at least one wall of the filter assembly. Systems may include a source of recovered fluid from a wellbore operation; a filtration unit receiving the recovered fluid and isolating a fraction of solids from the recovered fluid, the filtration unit having a backflush mode in which the fraction of solids is evacuated from the filtration unit; and a defluidizing tank receiving the evacuated fraction of solids to generate a filtrate and dried solids.

Abstract: A recovered fluid may be flowed through a portable fluid filtration apparatus for filtering the recovered fluid and forming a filtered fluid. The portable fluid filtration apparatus may have or include a fluid filtration platform in fluid communication with at least one self-cleaning filter component. The fluid filtration platform may have at least two segments where a first segment is configured to be attachable to a second segment. Each segment may include at least one inlet, at least one outlet, and at least one valve. In a non-limiting embodiment, the portable filtration apparatus may be in fluid communication with an oilfield fluid filtration system.

A fluid filtration system may have or include at least one first tank comprising a recovered fluid, a fluid filtration apparatus in fluid communication with the first tank, and a second tank in fluid communication with the apparatus. Another fluid filtration system may have at least one charge pump, a fluid filtration apparatus in fluid communication with the charge pump(s), and at least one salt water disposal pump in fluid communication with the apparatus for pumping a fluid into salt water disposal wells.
