Technical file PREFABRICATED WATER DEPURATIONS PLANTS MONOBLOC PARALLELEPIPED TOTAL OXIDATION PLANTS FROM 30 TO 200 EQUIVALENT POPULATION WITH SBR REACTOR OXI/SBR series WHAT ARE TOTAL OXIDATION PLANTS OXI/SBR SERIES Monobloc parallelepiped prefabricated plants type EURO MEC OXI/SBR series for residential areas from 30 till 200 equivalent population are dimensioned in order to guarantee the acceptance limits to the discharge foreseen by the Directive 91/271/CEE for discharge in superficial water and foresee the functioning of the active sludge biological reactor “S.B.R.” (Sequencing Batch Reactor). This technics fully tested is suitable to solve treatment problems when local requirements prevent from the application of traditional systems, particularly when hydraulic flow rates and organic loads are extremely discontinuous, like for example those of tourist resorts, restaurants, hotels, kitchens and canteens, dairies, food industries, wine cellars, dye-works and laundries. Monobloc parallelepiped prefabricated plants type EURO MEC OXI/SBR series of simple construction and functionality, permit a notable working flexibility, high clarifying efficiency, extremely reduced maintenance, odour and noise absence. Monobloc parallelepiped prefabricated plants type EURO MEC OXI/SBR series are principally composed of a parallelepiped tank horizontal axe, equipped with self-polishing membrane air diffusers and clarified water discharge pump submersible type. Besides the supply includes the blower type side channels for the production of compressed air and the general command and protection electric panel with relative working logic. The basins of the prefabricated monobloc tanks type EURO MEC OXI/SBR series are composed of monolithic basins made of reinforced concrete to guarantee any leak absence and any absence of ground infiltrations and can be installed even in presence of ground water. HOW TOTAL OXIDATION PLANTS OXI/SBR SERIES WORK Monobloc parallelepiped prefabricated plants type EURO MEC OXI/SBR series foresee the functioning according to the “S.B.R.” technology (Sequencing Batch Reactor), that combines to the process quality the discontinuous flow reactor flexibility obtaining guarantees and efficiencies hardly comparable to traditional plants. Plants structured with this particular technology are suitable for the industrial discharges treatment as they are insensible to the changes either of the hydraulic or of the organic load typical of the effluents The S.B.R. reactor differs from continuous traditional plants as the two principal functions of the active sludge process, biological oxidation and final clarification, happen in the same tank. The sedimentation phase is obtained by stopping the sewage aeration system so as to determine a situation of calm inside the oxidation tank and the consequent active sludge decantation on the bottom of the tank, leaving so on the surface a clarified water layer, that is conveyed to the discharge by means of a particular submersible pump. The functioning of the blower providing the air necessary to the biological process is commanded by electronic programmers, that consent to arrange working cycles changeable according to the requested operational requirements. USED MATERIALS Tanks : By request highly resistant reinforced vibrated concrete painted steel fiberglass concrete (if requested class D 400 cast iron) galvanised steel and polyethylene stainless steel AISI 304 SPECIFICATION “Supply of total oxidation prefabricated depuration plant made of reinforced concrete type EURO MEC OXI/SBR series composed of a parallelepiped monolothic tank made of reinforced concrete horizontal axe with functioning according to “S.B.R.” technology, complete with sewage inlet and outlet connection pipes, inspection shafts made of concrete, electroblowers type side channels, selfpolishing membrane air diffusers, submersible electropump for clarified discharge water, level regulators, command and protection electric panel with timer and all other electromechanical parts for the correct functioning.”
