Abstract
A sediment retention device including a water-permeable outer containment structure, a water-impermeable injection tube including an outlet disposed within the outer containment structure, and a flocculent treatment material disposed within the injection tube. The injection tube can include an agitation structure to promote mixing contaminated water with the treatment material. A baffle including water distribution openings can be disposed over the outlet to distribute water into the outer containment structure.
Claims19
A sediment retention device, comprising:
- a water-impermeable injection tube having an inlet at a first end and an outlet at an opposing second end;
- a treatment material disposed within the injection tube;
- a water-permeable outer containment structure including a containment chamber and a structure inlet connected around the injection tube proximate to the first end, the water-permeable outer containment structure surrounding at least a portion of the injection tube and enclosing the at least a portion of the injection tube within the containment chamber, wherein a liquid flowing from the outlet enters the outer containment structure, and
- a baffle disposed within the containment chamber in combination with and over the outlet of the injection tube, the baffle defining a baffle chamber around the outlet of the injection tube and the baffle including openings connecting the baffle chamber with the containment chamber.

A sediment retention device, comprising:
- a water-permeable outer containment structure enclosing a containment chamber and including a chamber inlet;
- a water-impermeable injection tube including an inlet and an outlet, wherein the chamber inlet is connected around the injection tube and the outlet is disposed within the containment chamber, the injection tube including a first section extending from the inlet, a second section extending parallel and adjacent the first section, and a third section extending parallel and at least partially adjacent to the second section, wherein the first section, second section, and third section are each connected by bends in the injection tube and disposed within the containment chamber;
- a baffle disposed around a portion of the injection tube including the outlet, the baffle including water distribution openings connecting a baffle chamber to the containment chamber, wherein water from the outlet passes through the baffle chamber and the water distribution openings to enter the containment chamber;
- and
- a first treatment material in a first pouch within the injection tube;
- and
- a second treatment material in a second pouch within the injection tube.
