Before nineties, the main objective of the Wastewater Treatment Plants was the organic matter reduction, and the pathogenic organisms in sewage and suspended solids reduction. Later the negative effects from the nutrients presence were discovered. Those consisted basically on nitrogen and phosphorus in the natural environment. Nowadays wastewater treatment plants are being designed to achieve effluent nitrogen and phosphorus concentrations that are not harmful to the environment. For that reason many WasteWater Treatment Plants (WWTP) have been modified in order to achieve higher yields in nitrogen and phosphorus removal. This job examines the current situation of the Crispijana WWTP , located on Vitoria-Gasteiz (west-Alava), analyzing the flows and the characteristics of the influent wastewater in order to modify and optimize the existing treatment system. To improve the wastewater plant performance, phosphorus removal by physical - chemical processes or biological processes has been considered. The biological phosphorus removal produces a sludge with high concentrations of phosphorus, magnesium and ammonium, which favors the subsequent recovery thereof by a crystallization process in the form of struvite. This recovery helps prevent foreseeable shortage as finite element in nature, giving a resulting product that can be used as fertiliser. The study of the required modifications of the treatment system has been carried out using the computer simulation tool DESASS (Design and Simulation of Activated Sludge Systems). With this tool the operating conditions for achieving adequate process performance and proper sizing of the elements are obtained. These operating conditions are, among others: sludge retention time, internal recirculation flow rate and dissolved oxygen concentrations. In the simulations performed, effluent phosphorus concentrations below 1mgP/l and effluent nitrogen concentrations below 10mgN / l have been achieved for each of the alternatives proposed, fulfilling the quality set by the European Directive 91/271 / CEE. For choosing the most appropriate solution , the investment (civil works , equipment, ... ) and exploitation costs (reagents, sludge disposal , energy, sale of struvite ) have been calculated for each of the proposed alternatives , selecting which is most technically and economically viable.Universitat Politècnica de ValènciaBarat Baviera, RamónSerralta Sevilla, JoaquínDepartamento de Ingeniería Hidráulica y Medio AmbienteInstituto Universitario de Ingeniería del Agua y del Medio AmbienteEscuela Técnica Superior de Ingeniería de Caminos, Canales y PuertosRepositorio Institucional de la Universitat Politècnica de València Riunet20172017-01-1620152015-07-07master thesishttp://purl.org/coar/resource_type/c_bdccinfo:eu-repo/semantics/masterThesisapplication/pdfhttps://riunet.upv.es/handle/10251/76809reponame:RiuNet.
