    Abstract: Fluid distribution filters having spiral filter media and associated systems and methods are disclosed herein. In one embodiment, for example, a filter assembly can include a canister having a body portion positioned between a first opening and a second opening. The filter assembly can further include a filter media positioned in the body portion of the canister. The filter media can include at least one channel in fluid communication with the first and second openings. The channel can have a spiral-like shape and be configured to distribute incoming fluid across the filter media and move the fluid at a substantially equal velocity across the filter media.

  • Publication number: 20130206700
    Abstract: Aspects and embodiments of the present disclosure are directed to apparatus and methods of filtering a fluid to reduce a level of at least one contaminant therein. The filtering of the fluid may be accomplished with a radial flow filtration column comprising a fluid chamber having an inlet, an outlet, and a side wall, an inner permeable retainer positioned in the fluid chamber, an outer permeable retainer positioned in the fluid chamber spaced apart from and surrounding the inner permeable retainer, a media bed compartment formed between the inner permeable retainer and the outer permeable retainer, a media bed comprising zero-valent iron disposed within the media bed compartment, and an adjustable element biased into the media bed compartment and configured to maintain a predetermined packing density of a media bed to be disposed within the media bed compartment.

  • Publication number: 20130200000
    Abstract: Sorbents prepared according to the invention useful in remediation of polluted effluents including waste waters and other fluids such as air, the invention is particularly directed to use of sulfidized red muds in treatment of sanitary waste waters to substantially remove or reduce bacterial levels such as fecal coliform as well as phosphates and total dissolved solids (TDS). The sulfidized red mud sorbents of the invention are derived by sulfidation of red mud, a waste product of Bayer processing of bauxite ores, red muds being sulfidized by reaction with sulfidizing agents including H2S, NA2S, K2S, (NH4)2S and CaSx as examples. Sulfidized red muds used according to the invention typically exhibit a sulfur content from about 0.2 to about 10% above residual sulfur in the red mud used as the starting material for preparation of the sulfidized red mud sorbents used in the presently disclosed methods.
