    摘要: Sulfidic water containing H2S and NH3, or alkali metal or other cations forming water soluble sulfides, is mixed with water containing salts of such cations and possibly excess SO2, then sent to an H2S stripper for treatment with air to produce a sulfide-depleted liquid effluent. H2S evolved from the stripper is burned to form SO2 which is absorbed in an SO2 absorber. A portion of the liquid effluent from the H2S stripper is used as solvent in the SO2 absorber which forms additional water containing ammonium and possibly excess SO2 salts for mixing with additional sour water.

    摘要: Water contaminated with pathogenic microorganisms is passed over a silver anode of an electrolyte cell in a layer 1 to 4 mm thick. The anode surface and the rate of water flow through the cell are related according to the equation F .gtoreq. c .times. V, wherein F is the anode surface area in cm.sup.2, V is the water flow rate in cm.sup.3 /second and c is a constant of the dimension sec/cm, with a value of 2 to 5. The density of the current in relation to the area of the anode surface is between 1.5 and 3.0 mA/cm.sup.2 and the voltage is such that active oxygen is generated at the anode. The effluent from the cell is safe to drink.

    摘要: A system for purifying bodies of water, such as swimming pools, includes a prefilter upstream of a catalytic filter, and a pump for periodically circulating water to be treated through the prefilter and then through the catalytic filter. The catalytic filter includes a series of horizontally disposed filter elements each having a stationary layer of a permeable water-purifying biocatalyst composition. The preferred biocatalyst is a microbicidal surface compound formed by wet processing finely divided silver oxide, zinc oxide and lampblack. Water circulated through the prefilter is filtered to remove suspended solids or algae which would clog or otherwise disturb the biocatalyst filter cake. Water circulated through the catalytic filter is purified by surface contact with the biocatalyst. Repeated pool water contact with the biocatalyst generates a residual microbicidal condition in the pool water. The biocatalyst layer, the water circulated to it, and the water circulated away from it are constantly maintained at a pH above 7 and at a temperature between about 70.degree. F to about 98.degree. F to prevent deactivating the biocatalyst and to constantly maintain the residual microbicidal condition.

    摘要: Automatic marine sewage treatment through a pair of tanks with salt water based sewage fed to the first tank after removal of solids above a predetermined size. Circulation means responsive to liquid levels in the tanks cause batch transfer of liquids from the first tank to the second tank and multiply circulate a stream of liquids from and to the second tank while filling the first tank. Electrolytic treatment subjects the stream to D.C. current flow, producing treating chemicals. Treated liquids are discharged from the second tank when the first tank reaches a control level, delivering a predetermined fraction of the treated liquids to the first tank.
