  • Patent number: 6986843
    Abstract: Water purifier includes a container having a room, a filtering material disposed in the room for purifying water for catching particles and fungi such as polio viruses. The filtering material is a sintered activated carbon block filter having pores. The filtering material preferably has a first filtering material and a second filtering material. One thing out of the first filtering material and the second filtering material is formed of a sintered activated carbon block filter whose average pore diameter is relatively small and whose amount of penetrating water is relatively small per unit time. Another thing out of the first filtering material and the second filtering material is formed of a sintered activated carbon block filter whose average pore diameter is relatively large and whose amount of penetrating water is relatively large per unit time.

  • Patent number: 6716366
    Abstract: Novel compositions are described for use in nitrate removal and treatment of water such as water and wastewater streams produced by processes in mining operations, agriculture industries operations, industrial operations, military operations, etc. These novel compositions are also useful for the treatment of water and wastewater streams associated with the running of industries and with the production and maintenance of livestock. Advantages of these novel compositions include use of them without need for pH adjustment and/or the presence of electropositive metals, inorganic acid, or alkaline compounds. One embodiment of these novel compositions comprises: (1) a sufficient amount of organic modified clay, (2) a highly crosslinked carbohydrate polymer with branched-chain structure containing sulfide and/or disulfide groups, or an alloy or blend of such a polymer with triazine-trithione sodium salt, (3) high swelling sodium bentonite or calcium bentonite, and (4) activated carbon.

  • Patent number: 6699561
    Abstract: An activated carbon molded body, more particularly in honeycomb form and for use as an adsorption filter, can be produced from a mixture including activated carbon, water, novolak powder, clay, cellulose ether, liquid starch, wax, polyacrylamide and soap, by a procedure involving thoroughly mixing the constituents, extruding the mixture to form a monolithic molded body and cutting same to size, drying the body and effecting pyrolysis thereof. The adsorption filter produced therefrom can be regenerated by electrical heating under specified conditions.

  • Patent number: 6429165
    Abstract: A polymer-bonded granular adsorptive, absorptive, chemisorptive, or catalytically active material and a process for producing molded bodies from this material. An objective was to develop a polymer-bonded granular adsorptive, absorptive, chemisorptive, or catalytically active material which is capable of forming an open-pore and sorptive foamed body at increased temperatures while not reducing the specific surface of the active material and with a binding effect only during the mixing and processing phases, as well as a process for producing molded bodies from this material. This objective was met by mixing and processing an adsorptive, absorptive, chemisorptive, or catalytically active fine-grained material together with a finely particulate, meltable polyethylene with the addition of a binding agent having an oligocondensate basis.
