The aim of this paper was to accurately analyze the sources of water pollution and loading concentrations in textile finishing mills. A process data collection was performed and integrated with a characterization of the process effluents in terms of treatability and reusability. In order to evaluate properly the wastewater loading, an analysis course was set. The samples have been gathered for two months; instantaneous samples (PI) were drawn from the wastewater, as well as from the painting baths, at the time of the overflow. Based on several daily average values, a general average (PG) has obtained. The experimental data were statistically analyzed and the average values of the investigated parameters for each collecting point corresponding to the sectors of the finishing section were assessed..

Taking into account the statistical data gathered in two previously published papers concerning the pollution sources in the production sector, namely Finishing section, various solutions are proposed for wastewater treatment. Bearing in mind the results obtained through the sampling method on different types of water in the urban sanitary sewer system, the conclusion was that the most convenient alternative, besides the source control is the treatment in wastewater treatment plants. This is due to the wastewater recycling systems which no longer ask for the optimization of the dilution treatment, through water supply from other systems. A chart of the reengineered sewage treatment works was also proposed.
