| dc.description.abstract | Due to large-scale industrial development in the quality of natural resources, among which stands out the water, is very deterioradadue. Waste from textile industries have low levels of degradation, so could pollute the water sources in which they come into contact, they had characteristics of being persistent in the environment. Therefore, this study was to apply the technique of electroflocculation using sacrificial electrodes of aluminum (Al) in a liquid effluent from a textile industry to estimate the frequency of exchange of the same when applied to textile effluent by applying the technique of statistical process control. Were used throughout experimental procedure two aluminum electrodes, connected independently, without direct contact with each other, connected to a DC source, under optimum conditions of electrical current, electrical conductivity and reaction time, where the effluent was in contact direct. The removal efficiency of turbidity and color parameters of the electrochemical test and control group was calculated using the raw effluent. Through experimental run as a whole, can be seen that the removal efficiency of color and turbidity parameters in textile effluent to be analyzed was more significant in electrochemical process in virtually all trials, compared to the control group. Regarding the efficiency of sacrificial electrodes used in electrochemical treatment, one can see that even whit the physical structure being damaged efficiency was maintained throughout the process. | |
