DESIGN AND CONSTRUCTION OF PREMANUFACTURED GAS SEPARATORS FOR THE WASTEWATER INDUSTRY

The most important part of an UASB (Up Flow Anaerobic Sludge Blanket) reactor is its gas separator, wich is why it takes most of the time service and expenditure. In this project, the problems and difficulties of metalic and polymer gas separators are analysed. In order to avoid these difficulties, a concrete premanufactured gas separator of type 5 cement was suggested; after selecting its geometric from, the thickness of the concrete was designed and calculated from the point of neutralizing the buoyant forces. Having considered the cases mentioned above, the constructional calculations were done. After designing the metalic model, a sample of 5.30m lenght, 0.82m width and 0.48m height was constructed in The Water and Energy Research Center. The desired result was obtained from the point of constructional resistance and leackage of CO2 and Ch4.
