Abstract: In removing color components and COD components from waste water, the waste water is treated with an inorganic adsorbent, the mixture thus obtained is subjected to a sedimentation treatment to separate the adsorbent adsorbed the color and COD components as a slurry layer, and a portion of the adsorbent slurry is returned to the adsorption step and the remainder thereof is subjected to a regenerating treatment to recycle as an adsorbent.Pollution-free water is effectively obtained by the above method.

Abstract: Treating water with various grades of attapulgite clay and sepiolite using contacting or percolation techniques removes substances not removable by standard water purification methods under many conditions. Substances such as pesticides, toxins, hormones, heavy metal cations and viruses are removed from water by adsorption upon the clay surface. When contacting is employed, the clay containing the adsorbed substances is subsequently removed by sedimentation or filtration. The clays can be regenerated by appropriate chemical or thermal techniques.

Abstract: The invention provides an adsorbent suitable for column packing which is composed of a granular material obtained by subjecting a mixture of an activated sludge-containing material and a primary condensate of a formaldehyde type resin and/or a dialdehyde compound to heat-curing and granulating. The adsorbent can advantageously be used to treat industrial waste water containing ionic or nonionic water pollutants such as heavy metal ions, dyes, surfactants, high molecular weight coagulants and mineral oils.

Abstract: The specification describes an oxidation and adsorption method for removing contaminating materials (pollutants) from aqueous liquids. The liquids are first subjected to an electrochemical treatment for the purpose of coagulation or agglomeration and partial oxidation by addition of NaOCl. Following this, using sedimentation and/or flotation, the agglomerated and coalesced sludge is removed from the liquid. In the liquid an excess of OCl.sup.- remains and this liquid, enriched in this manner, is supplied to adsorption columns, in which inorganic adsorption compositions are located having a high specific surface area so that a further oxidation is achieved by the excess OCl.sup.-, together with a partial adsorption and by addition of O.sub.3, complete oxidation is achieved. The organic contaminating materials are converted into CO.sub.2 products of adsorbing materials of different grain sizes and specific surface areas made of inorganic materials, following which the CO.sub.2 escapes from the liquid and is stored. The thus cleaned liquid then leaves the oxidation and adsorbing columns.
