Optimización de los procesos de tratamiento de agua potable: coagulación-floculación y filtros de carbón activado granular en la ETAP Ampolla


Larroca Padrol, Arnau

Throughout history, the Ebro river has been the main water supply for the rice farmers in the delta, but in the 80s there was a drought in the province of Tarragona, the chemical industries required a lot of water for their production and water resources in Tarragona were insufficient. for the inhabitants and the industries, for this reason a transfer of water was made from the Ebro river beyond Tarragona to supply all the inhabitants and the industries, in this way the irrigation conditions for the farmers of the Ebro delta were also They improve by improving their infrastructures, but the high demand for water causes a problem of lack of optimization of the purification process network. To ensure a good optimization of the water reagents and improve the configuration of the purification process, a project will be carried out with new technologies for the drinking water purification plant (ETAP), to guarantee optimal working conditions.
This project will try to optimize a river water purification plant, due to the great demand for water due to the increase in population and the appearance of new laws due to the high degree of demand for water purification require a calculation of the optimization of the reagents. of the plant to ensure the optimum level of water quality obtained. To carry out the optimization of the reagents, different studies will be carried out with the coagulation-flocculation-sedimentation laboratory (Jar-test), which consist of a process of continuous agitation in 6 different flasks and the addition of different concentrations of coagulant and flocculant, then evaluate the results obtained and make the best option for the process. Currently there is a camera with integrated software that can analyze the coagulation-flocculation process and facilitates the evaluation of the results with the concentration of the reagents.
For the filtration optimization process, a piloting of the plant will be used during a continuous process with different carbon samples and it will be optimized to see what type of activated carbon performs the best filtration process, maintaining the water quality values ​​established by environmental legislation.
