Resumen
The main objective of this work is to evaluate the efficiency of color removal of wastewater generated in a textile industry in Goioerê, a city in Parana State, Brazil, through the ozonation process. To assist in the development of this objective 4 temporal sampling profiles were carried out to determine physical-chemical parameters such as temperature, pH, turbidity, conductivity, true color, bicarbonate alkalinity, volatile acids, chemical oxygen demand (COD), total solids, suspended solids and dissolved solids. The samples were collected near to the effluent treatment plant of the industry and outlet and both were exposed to ozone for 5 and 2 hours, respectively. The ozone generator used for treatment generated 1085.25 mgO3/h and air flow of 8 L/min. The average removal of color was 88% similar to 90% mentioned in the literature. The color removal is a major problem for treatment plant effluent textile so it is possible to consider the ozonation process efficient for this area. The color removal efficiency for both the influent and effluent was significant with an average of 85% and 90% respectively.
