Seleção de tecnologias de tratamento de água em função do tratamento, aproveitamento e disposição dos resíduos gerados nas etas

Resumen
This article presents the conceptual model of the selection of surface water treatment techniques involving treatment, utilization and removal of the wastes generated in the water treatment plants (WTPs) with flow rates between 10 L/s and 100 L/s. The model benefits small – and medium – sized Brazilian communities. The development of the model required the study of several factors that allowed defining the variables and indicators of selection, which formed the conceptual selection model (CSM) with seven sublevels, which are interconnected. The model progressively selects the water treatment plans with higher sustainability likelihood, according to the input data (F), criteria (A), procedures (B) and selections (S) established in its development. It was possible to conclude that the applicability of CSM is restricted to the WTPs that meet all the domain requirements established. However they do not eliminate the design engineer from evaluating other techniques of treatment, utilization and disposal of the wastes which are not take into account by this model. It was also concluded that the selection of the technology for treatment, utilization and disposal of the wastes should not be evaluated independently of the one selected in the WTPs.
