This invention is a single stage or a multi-stage apparatus for chemical, physical-chemical, and biological treatment and equalization of variable flows of influent material, wherein said influent material is processed in at least a single reactor or in a plurality of sequential reactors containing liquid and having influent, and having reactor connecting and effluent lines. The improvement to this apparatus comprises: (1) using at least one reactor for flow equalization, the said reactor is a separate reactor or a reactor selected from the said plurality of sequential reactors, (2) providing the lower elevation flow transfer means attached to the said reactor connecting and effluent lines in the said selected reactors, (3) providing at least one higher elevation flow transfer means attached to the said reactor connecting and effluent lines in at least one of the said at least two selected reactors for the flow equalization, the said at least one of the said at least two selected reactor precedes the said other selected reactors in the plurality of sequential reactors.

210/603000

A method of biological treatment of wastewater laden with organics in a reactor having a biomass, the wastewater and biomass form mixed liquor, a treated wastewater, biological gases, and new biomass are generated in the reactor, biomass is separated from the treated wastewater by vaporization and condensation and is at least partially retained in the reactor, and further providing at least one step of physical-chemical treatment of said mixed liquor prior to the vaporization, whereby the free dissolved volatile gases are substantially removed from the mixed liquor and the efficiency of said biomass and wastewater separation by vaporization is improved. The main biological gases are carbon dioxide and methane. Carbon dioxide is converted into well soluble and non-volatile bicarbonates, poorly soluble methane is separated and collected from the bicarbonate rich mixed liquor as a methane-rich biogas, and carbon dioxide is than stripped by air by disproportionating bicarbonates into carbon dioxide and calcium carbonate in a carbon dioxide stripper.

A method for fluidization of a particulate bed material in a fluidized bed reactor with an upflow of fliud being treated, wherein a step of recycling said treated fluid is provided and further comprising the steps of (a) uniformly collecting at least a portion of the fluid above the fluidized bed and lifting this fluid by at least one gaslift having an intake above the bed, and (b) recycling the lifted fluid under the bed via at least one downcomer positioned within the bed. An generic apparatus for conducting the method steps in a variety of applications is also provided. The fluidized bed reactor can be used for chemical, physical chemical, biological processes, and combinations thereof in the chemical processing, food, environmental and other industries.

A multistage biological treatment method receives material to be treated, and passes the material through multiple reactors. From each reactor some of the contents are removed and separated, and the biomass is moved into the previous stage while the material to be treated and metabolic products are moved into the succeeding stage. Thus, the predominant flow of the biomass is upstream and the predominant flow of the material to be treated in downstream. Preferably, alternate reactors are anaerobic, and alternate reactors are aerobic, so the material is alternately subjected to anaerobic, then aerobic, environments. The process can be improved by applying physical, physical-chemical, chemical, and biochemical actions to the treatment system.

A system for wastewater and sludge treatment utilizes an anaerobic reactor to modify the wastewater and generate sludge and liquid effluent. The sludge is transferred to a conditioner wherein anaerobic, aerobic and chemical means may be utilized to cultivate the required strains of organisms and break down various pollutants. Various chemicals may be solubilized, or precipitated, or adsorbed to remove them from the waste stream. Aerobic conditioning may be used to increase the volume of sludge, and to increase the temperature of the sludge. A shell having multiple compartments can provide for the entire process by utilizing the upper portion for anaerobic reaction and the lower portion for conditioning. An aerobic reactor can be disposed centrally of the conditioning compartments. Pipes and pumps can be used to transfer components from one compartment to another, and to discharge the cleaned effluent.
