    Abstract: A method and apparatus for anaerobic treatment of organic wastes in a liquid filled vessel wherein particles of the waste are buoyed and form a floating bed in the liquid by the gasses generated by the anaerobic digestion of the wastes. The bed forms to an upper stratum of the least digested, least dense waste and a lower stratum of the most digested, most dense waste. Liquid from beneath the bed is continuously sprayed over the upper surface of the bed through a series of discharge ports which expands to bed downwardly. Each spraying period is followed by a quiescent period to allow the bed to reform. Over time the floating bed is moved from an inlet end to an outlet end of the vessel where the most digested waste is removed.

  • Publication number: 20020108908
    Abstract: An affinity matrix for use in affinity based molecular pull down and immunoprecipitation procedures. The affinity matrix comprises a polymeric support, a dye attached to a fraction of the polymeric support to enable optical detection of the polymeric support, and an affinity ligand other than the dye attached to a fraction of the polymeric support for the capture of a molecule.

  • Patent number: 6432306
    Abstract: A process based on ion exchange with separated beds is disclosed for the deionization of substances that are not stable in the presence of strongly acidic cation exchangers, wherein the solution to be deionized is contacted with a first bed consisting of a basic anion exchanger in the form of hydrogen carbonate and subsequently with a second bed, connected in series, consisting of a weakly acidic cation exchanger in hydrogen form.

  • Publication number: 20020104810
    Abstract: Disclosed is filter aid formed of a crushed foam glass utilized as a filtering aid for removing suspended materials in a fluid stream by first providing a permeable support with the crushed foam glass filter aid placed adjacent thereto, and directing the fluid stream having suspended materials through the filter. Suspended materials within the fluid stream are captured on the crushed foam glass filter aid, separating the suspended materials from the fluid stream. The foam glass filter aid and the suspended materials may then be removed as a mixture, melted to form a molten glass, fritted to form a frit, comminuted to form a foam glass precursor, mixed with precursor with a foaming agent and heated and crushed to reform the foam glass filter aid. Suspended materials captured on the crushed foam glass filter aid are thus removed from the foam glass filter aid, and the foam glass filter aid to be recycled and used again in the filtering process.

  • Publication number: 20020104803
    Abstract: A novel process and apparatus are disclosed for cleaning wastewater containing metal ions in solution, hydrogen peroxide, and high solids, e.g., greater than about 50 mg/l particulate solids. A carbon adsorption column removes hydrogen peroxide in the wastewater feed containing high solids. A ion exchange unit removes the metal ions from solution. The process and apparatus remove metal ions such as copper from a high solids byproduct polishing slurry from the chemical mechanical polishing (CMP) of integrated circuit microchips to form an environmentally clean wastewater discharge.

  • Patent number: 6428697
    Abstract: Methods comprise processing wastewater to produce useful products. Preferably wastewater is ash leachate from landfills which is processed using magnetohydrodynamic treatment followed by electrolytic cell treatment to produce sodium hypochlorite. Methods further comprise removal of hazardous substances from wastewater for subsequent storage and processing of wastewater.

  • Publication number: 20020079259
    Abstract: The column is provided for carrying out an isotope exchange (EM) between a liquid substance (L) and a gaseous substance (G) using a catalytic reaction (EK). In this reaction the isotope exchange between molecules of the vaporized liquid substance (V) and molecules of the gaseous substance (G) takes place through a heterogeneous catalysis. The column comprises a plurality of modules (M) which are arranged vertically one above the other and which are in each case subdivided into two regions K and A which are serially connected by a connection region (C). The catalytic reaction can be carried out in the region K on a first packing (2). A substance exchange (E1, E2) between a liquid and a gaseous phase which contains vapor can be carried out in the region A by means of a second packing (3) for compensating substance concentrations. During the operation of the column a transport of the gaseous substance (G, V) which contains vapor is driven through the modules as a result of pressure gradients.

  • Publication number: 20020070163
    Abstract: A wastewater treatment system for use with a conventional septic tank, or other small-scale wastewater treatment facility, for enhancing wastewater treatment without requiring complex control or maintenance limitations. The system incorporates a plurality of primary functions that combine to oxidize, nitrify, denitrify and remove water borne total dissolved solids prior to effluent discharge. Included is a fluidized-bed reactor containing biofilm attached to carrier particulates for use in the purification of wastewater. The fluidized-bed reactor is configured to include two distinct regions, namely a “lower” aerobic region and an “upper” anoxic region, during normal operating conditions. The lower aerobic region uses aerobic facultative bacteria to oxidize Carbonaceous Biochemical Oxygen Demand (CBOD), organic (Kjeldahl) nitrogen, and ammonia while consuming the dissolved oxygen in the water.
