“…Thus, only the biological treatment was not sufficient to obtain proceeds to satisfy the law, whether the effluent should be treated previously by physical-chemical or chemically. Salazar (2009) also reported the importance of a pretreatment for effluent with high organic load before aerobic biodegradation process [9,20,22].…”

Vinasse is the main residue generated during alcohol, sugar and blue rum production by fermentation process. This residue is effluent that could cause serious environmental pollution due to high organic load when is not treated adequately. The aim of this work consists of evaluating the efficiency and application of heterogeneous photocatalysis with TiO 2 , followed by a biological treatment (activated sludge system) to reduce organic load in the referred effluent. Complete factorial designs indicated the best experimental conditions subsequent to photacatalytic and biological treatments providing a reduction of non-purgeable organic carbon (NPOC) as a variable response. After the photocatalytic process, the sample from the best experiment condition was treated by a biological process in order to verify the degradation efficiency of the effluent organic matter studied according to the hybrid system (Advanced Oxidation Process-Activated Sludge System). This system, which presented more efficiency, had a photochemical treatment of 180 minutes carried out in aerated solutions, pH 9 and effluent in natura, while the biological treatment was performed at pH 8 and sludge concentration of 5 gL -1 . The reduction of biochemical oxygen demand (BOD) was >80%.

“…There are many types of AOPs applied for the oxidation of pollutants in water and wastewater, as catalytic ozonation (O 3 ) [19] [20], or combination of hydrogen peroxide with ozone (H 2 O 2 /O 3 ) or ultra violet (H 2 O 2 /UV), and UV/titanium dioxide [21] or UV/zinc oxide [22], treating pollutants by oxidation and by hydroxyl radical [23]. Despite AOPs have been widely studied to reduce toxicity of various types of industrial effluents, the use of AOPs in the treatment of effluents from polyester resins facture has been little used.…”

This paper presents the Taguchi Method, a statistical design modelling for experiments applied in environmental engineering. This method was applied to optimize the treatment conditions of polyester-resin effluent by means of Advanced Oxidative Processes (AOPs) using chemical oxygen demand (COD) as response parameter. The influence of each independent parameter including respective interactions was evaluated by Taguchi Method, which allowed determining the most statistically significant variables and conditions to best fit the process. Results showed that Taguchi Method is a very useful tool for environmental engineering field and possible simplifications of analysis and calculations through commercially available software.
