Abstract
Methods, apparatuses and systems for filtering dewatered water utilizing primary and secondary containment mechanisms positioned on a portable sled, the primary containment mechanism of the system being a filter bag enclosed by an interior porous fence, the secondary containment mechanism including a filter medium positioned within a channel defined by the interior fence and an exterior porous fence and enclosing the filter bag. Water entering the filter bag exits the bag as filtrate which passes through the secondary containment mechanism and returns to the environment. The system is transported to a different location where filtering may continue utilizing the same filter bag enclosed within the interior fence.
Claims23
A portable water filtration apparatus, comprising:
- a sealed base such that water is not able to pass therethrough;
- an exterior fence extending upward from the base and bounding a major internal area, the exterior fence having openings to allow water to pass outward therethrough during operation;
- and
- an interior fence extending upward from the base and bounding a minor internal area, an entirety of the minor interior area oriented over the sealed base, the interior fence having openings to allow water to pass outward therethrough during operation, the exterior fence and the interior fence defining a filter medium placement channel in which is positioned a filter medium, a filter bag positioned within the minor internal area for capturing filtrides within the bag while allowing filtrate to pass through the bag, and piping for supplying water to the bag.
A portable filtration system, comprising:
- a sealed metal base such that water is not able to pass therethrough;
- an exterior fence comprising spaced-apart outer posts connected to the base defining openings to allow water to pass outward between adjacent outer posts, the exterior fence bounding a major internal area;
- an interior fence comprising spaced apart inner posts defining openings to allow water to pass between adjacent inner posts, the interior fence positioned within the major internal area and bounding a minor internal area, and together with the base and the exterior fence, defines a filter medium placement channel to receive a filter medium, the channel wrapping around the minor internal area;
- a filter media positioned in the filter medium placement channel;
- and
- a filter bag positioned within the minor internal area to capture filtrides within the bag while allowing filtrate to pass through the bag.
A portable filtration apparatus, comprising:
- a sealed base such that water is not able to pass therethrough;
- an exterior fence positioned about a perimeter of the sealed base and comprising a plurality of spaced-apart vertical posts connected to the sealed base and a plurality of horizontal structures spanning the distance between adjacent vertical posts thereby forming segments having sufficient structure to hold a filter media in place while also allowing liquids to pass outward between adjacent vertical posts, the exterior fence bounding a major internal area;
- an interior fence extending from the sealed base and bounding a minor internal area comprising a plurality of spaced apart inner vertical posts and a plurality of horizontal rungs spanning the distance between adjacent inner vertical posts thereby forming segments allowing water to pass between adjacent vertical inner posts, the interior fence positioned within the major internal area and bounding a minor internal area, and together with the sealed base and the exterior fence, defining a filter medium placement channel for receipt of a filter mediation, the channel wrapping around the minor internal area;
- a filter media positioned in the filter medium placement channel;
- a filter bag positioned on the sealed base within the minor internal area for capturing filtrides within the bag while allowing filtrate to pass through the bag;
- and
- a lift tongue is provided within a front segment of said exterior fence for lifting said portable filtration apparatus.
