  • Inorganic material for removing harmful substance from wastewater and method of preparing the same, and method for wastewater treatment
    Patent number: 10052623
    Abstract: An inorganic material for removing a harmful substance from wastewater is provided. The inorganic material includes a plurality of porous silicate particles having a glass phase structure, wherein the plurality of porous silicate particles include silicon dioxide, aluminum oxide, barium oxide, cesium oxide, and boron oxide, and have a zeta potential of a negative value at pH of from 1 to 5, and wherein the average pore diameter of the porous silicate particles is in a range of from 3 to 50 nm. Moreover, a method for preparing an inorganic material for removing a harmful substance from wastewater and a method for wastewater treatment are further provided.

  • Process for chemically oxidizing wastewater with reduced sludge production
    Patent number: 6143182
    Abstract: A process to purify wastewater by chemical oxidation is disclosed. The purification is carried out in a fluidized bed of a suitable particulate carrier upon which the iron(III) compound produced by Fenton's reaction crystallizes or coats, thereby reducing the sludge content of effluent over 50%. In addition, the fluidized bed improves the COD removal by way of thoroughly mixing the wastewater with adding agents.

  • Method of wastewater treatment by electrolysis and oxidization
    Patent number: 6126838
    Abstract: Disclosed is a method for treating highly concentrated wastewater by electrolysis and oxidization, said method being characterized in that the electrolysis and oxidization are carried out in a fluidized bed of a suitable particulate carrier. The electrolytic reduction efficiency of ferric ions is improved by the fluidized particulate carrier, and thus a high proportion of iron(III) to iron(II) can be sustained in the system. This invention allows extensive purification of wastewater with improved efficiency.
