Abstract: A device that reclaims industrial fluids. Solid contaminants are removed from the liquid being reclaimed by a series of increasingly fine filter elements positioned within a filter housing. The substantially solid contaminant-free fluid then enters an evaporation chamber having a design that constrains the fluid to form a thin film atop an evaporation plate at the bottom of the chamber to facilitate evaporation of volatile contaminants. Insert members are positioned within the evaporation chamber to increase the surface area of the thin film to further enhance the removal of the volatile contaminants. The temperature and pressure of the evaporation chamber is controlled by a heating element that is under the control of a temperature sensor. Evaporated volatile contaminants escape the evaporation chamber through a port formed in the head that closes the device. Latches are used to secure the head in the absence of conventional nuts and bolts, and the head screw threadedly engages the evaporation plate.

Abstract: An iron removal system for a drinking water supply includes a synergistic combination of an oxidation/filtration unit and an activated carbon filter unit. The oxidation/filtration unit utilizes a manganese-treated zeolite in the form of normally undesirable fines. The problems of high pressure drop and difficult handling of zeolites fines are eliminated by utilizing a more porous radial tubular flow construction in which the fines are confined in a packed bed. The filter cartridge is made for disposal when exhausted. The series connected activated carbon filter continues to remove iron from the outlet of the zeolite filter long after the capacity for iron removal of the latter has exceeded desirable limits. The combined filter system is less expensive and easier to operate and maintain than a comparable regenerable prior art oxidation/filtration system for iron removal.

Abstract: A filter cartridge (10) for filtering liquid having an internal liquid trap (28). The cartridge (10) has a cylindrical housing (12) having a closed top end (14) and bottom end (16), and a side wall (30) which is perforated to allow liquid to pass through. A tube (22) extends from a liquid inlet (18) at the bottom end (16) of the housing toward the top end (14), where the tube (22) is open to allow the liquid to flow into the housing (12). The cartridge (10) includes a filter media (26) inside the housing spaced apart from the conduit (22) so that the filter media (26), the bottom end (16) and the length of the conduit (22) below where the conduit is open form a trap (28). This trap catches liquid flowing into the housing (12) through the conduit (22) whereby the liquid may escape the cartridge (10) only through the filter media (26) thereby preventing back flow through the conduit (22).

Abstract: This invention provides means whereby the liquid component can be separated from the solids in food waste and garbage.

Oil from the crankcase is filtered by the outer filter element and a substantial volume of the filtered oil flows to the primary lubricating circuit of the engine. A small percentage of the filtered oil is subjected to further filtration by the inner filter element and is returned directly to the crankcase. A tubular fitting extends between end caps on the two coaxial filter elements to establish communication between the inner filter and the mounting adaptor, to separate the two flow circuits, and to maintain a fixed axial spacing between the two filter elements.

The article of manufacture and method include the use of a water-holding material, e.g, a water-swellable clay, such as bentonite, for reducing the permeation of the contaminated water into the soil, and an inground treatment layer containing a material capable of adsorbing, absorbing, ion-exchanging, neturalizing or reacting with one or more water-soluble contaminants within the water for removing a substantial portion of the contaminants from the water so that the portion of the held water that permeates the water-holding layer, will be rendered substantially less contaminated.

Abstract: A composite cartridge-type filter effective to substantially reduce low but hazardous concentrations of lead in drinking water to acceptable levels utilizes a porous activated carbon block filter and a powdered deionizing resin which is converted to an ion exchange resin in situ and during use of the filter. The method of operation of the filter results in a substantially extended life for lead removal as compared to similar disposable cartridge filters. The composite filter is also effective in removing dissolved metals which are leached from the soluble ash fraction of the carbon block itself. Powdered deionizing resin, having a greatly enhanced active surface area as compared to the resin beads from which it is formed, is formed by fracturing the resin beads in situ in a slurry filling and drying process which provides a stable packed resin bed.

With the lid and outer perforated cylinder (exterior shell) removed, a removable and disposable filter unit may be placed within the outer cavity and similar, or different, filter medium may be placed within the inner cavity. The gaskets of the filter unit in conjunction with the lid, the base, the conduit, exterior shell and the inner perforated cylinder provide seals which prevent liquids from bypassing the filter unit.

Abstract: An antibacterial material for water comprising a carrier containing an antibacterial agent and a fabric surrounding it is disclosed. When this antibacterial material for water is placed in water, microorganisms living in the water would pass through the fabric and approach the carrier, so that they are attacked by the antibacterial agent contained therein and die. On the other hand, contaminants and slime in the water cannot approach the carrier since they are filtered off by the fabric. Therefore the surface of the carrier is hardly coated with contaminants or slime and kept in an exposed state. As a result, the antibiotic effect of the antibacterial material on the water can be maintained for a long period of time.

Abstract: The present invention provides an improved filtration system particularly adapted for use in a fluid circulation system in a moving body. The filtration system includes a filter body formed from a porous resilient material. The filter body is not designed to be limited to a predetermined space for a filter and thus greatly increases the filter area/mass ratio. The filter defines a large number of tapered and winding passageways which are oriented at a large number of different angles relative to the outer surface of the filter body. The passageways are sufficiently large to permit fluid and particles to flow through into them, but are sufficiently tapered so that any particulate matter within the fluid becomes entrapped in the tapered passageways. The walls of the tapered passageways are porous in micron and sub-micron dimension to freely pass fluid. Accordingly, fluid will freely pass through the filter but any impurities or particulate matter will be firmly retained within the tapered winding passageways.

Abstract: An oil absorbing and confining product includes a by-product from manufacture of wooden lead pencils and the like. Incense-cedar in its natural state has a natural hydrophobic constituent in a form of a natural resin material. During processing of incense-cedar wood for pencil making, various dyes and the like are added and in addition a small additional amount of wax is added. A waste by-product is generated in the form of fine shavings, fibers and sawdust which uniquely functions for oil absorption with rejection of water absorption. The material can be applied in its waste form to a water surface covered with oil or can be conveniently retained within a suitable flexible and porous covering such as a fabric sock or bag structure for use as a confining and absorbing dam member. The use of incense-cedar is readily destroyed through incineration or the like.
