| Sumario: | ABSTRACT: A novel anaerobic-anoxic reactor for biological nutrient removal (BNR) from wastewater has been conceived and presented in this doctoral thesis. The novel reactor, named AnoxAn, consists in a continuous upflow sludge blanket reactor, with an anaerobic zone at the bottom prior to an anoxic zone above. A clarification zone at the top of the reactor avoids the escape of large amounts of suspended solids, thus promoting high biomass concentration in a sludge blanket reactor type. The biological anaerobic-anoxic functioning of AnoxAn is meant to be coupled with an aerobic reactor and a secondary sedimentation unit (or a final filtration step), in order to complete the BNR treatment train. The reactor has been proved as a novel technology for BNR from wastewater. The experimental and theoretical results, obtained by means of pilot plant operation, modelling and simulations, demonstrate the feasibility of the novel reactor concept and its applicability for wastewater treatment. |
