    Abstract: A sequencing batch apparatus being manually or automatically operated for treating a contaminated water is described. The present invention specifically relates to the apparatus comprising an inlet pipe, a batch reactor, a chemical feeder means, at least one mixing means, a coarse bubble distribution means, a fine bubble distribution means, a liquid discharge means, and sludge discharge means for required liquid treatment, and further alternatively comprising a gas moving means, a gas pipe, a flow meter, an enclosure and a gas purification means for air emission control upon demand. The present invention further relates to an apparatus system comprising means for recovering precious metal, controlling optimum pH in an acid range, reducing hexavalent chromium to trivalent chromium, controlling optimum pH in a base range, oxidizing cyanide, destroying phosphite, separating flocs, exchanging metals, adsorbing contaminants, neutralizing an effluent, and controlling gas emission. The treated effluent can be safely discharged into a receiving water. The waste sludges, ashes and spent adsorbents containing metals, PCB, and other toxic organics are safely disposed of by cementation or solidification.

    Abstract: This invention relates to a new and novel method and apparatus for reacting nongaseous material with a gaseous reactant comprising introducing a first stream containing a nongaseous material into a reaction zone; simultaneously introducing a second stream containing a gaseous reactant into the reaction zone such that the gaseous reactant immediately contacts and reacts with the first stream thereby producing a gaseous product; forming a spiralling vortex within the reaction zone to cause substantial separation of gases, including the gaseous product, from the nongaseous material; forming and removing a third stream from the reaction zone containing the gaseous product which is substantially free of the nongaseous material before a major portion of the gaseous product can react with the nongaseous material; and forming and removing a fourth stream containing the nongaseous material from the reaction zone.
