Abstract: A system for removing sediment from water is disclosed. The exemplary embodiments described herein disclose a system comprising a filter chamber, having a deck positioned inside to divide it into an upper chamber and a lower chamber. The deck may have a plurality of holes to hold filtration elements and also may have a ridge or a skirt or both. An inlet line may be tangentially connected to the filter chamber and introduce influent liquid into the filter chamber below the deck and outside of the skirt.

Abstract: An apparatus, system, and method for removing sediment from water is disclosed. According to one embodiment of the present invention, the apparatus includes a tubular filter assembly comprising a support member; and a filtratable element surrounding the support member, the filtratable element comprising a backing mesh; and a fibrous batting. A system for removing sediment from water is disclosed. According to one embodiment, the system includes a filter chamber to receive a liquid having suspended particles therein; at least one filtration cartridge housed within the filter chamber, wherein the filtration cartridge comprises at least one elongated filtratable element, each filtratable element comprising a support member, and a filtratable media adapted to surround the inner core. A method for removing sediment from water is disclosed.

Abstract: A separator tank for separating and trapping contaminants in rainwater and runoff is disclosed. According to one embodiment of the present invention, the separator tank comprises a container having a bottom wall, side wall, and top wall defining an internal chamber; an insert located inside of the internal chamber, the insert comprising a weir defining an intake area between the weir and the side wall; and a round-edged orifice positioned within the intake area; an inlet conduit for introducing an influent liquid into the intake area; wherein the weir is positioned such that the weir induces the influent liquid to flow in a swirling motion within the intake area. According to another embodiment of the present invention an insert for a separator tank is disclosed. The insert includes a weir defining an intake area for receiving an influent liquid; and a round-edged orifice positioned within the intake area.

Abstract: Chitosan membranes chelated with silver or cuprous material may be used to separate olefins from a mixture of olefins and paraffins. The feed stream is humidified, demisted, treated to remove sulfur compounds and passed to a cell having a chitosan membrane containing chelated silver or cuprous compounds. The process has a reasonable flux rate and is operable at reasonable temperatures and pressures. The process could be used in an olefin separation train.
