Advanced oxidation processes (AOPs) were applied prior to biological aerobic treatment by means of activated sludge. Textile wastewater was chosen as an example of industrial wastewater and the chemical oxygen demand – COD – was an overall measure of biodegradable substrate concentration, while the biomass concentration was expressed by volatile suspended solids – VSS. The kinetic investigations were applied to synthetic wastewater consisting of anthraquinone dyestuff Acid Blue 40 C.I., anionic detergent Avivage KG conc., softening agent Tetrapol CLB and mineral salts. Kinetics of microbiological destruction of the pollutants were described by the Monod equation. The kinetic parameters of the equation: maximum specific rate of microbial degradation, affinity (Monod) constant and yield coefficient were identified from the experimental data obtained at laboratory scale. The influence of various AOPs on the kinetics of biodegradation was analysed. The experimental evidence of the positive effect of chemical oxidation pretreatment on the biodegradation of recalcitrant compounds was quantified by estimation of the kinetic parameters of the Monod equation employed in biodegradation of the wastewater.

As drought becomes pervasive around the world, many water suppliers are turning to water supplies once avoided – contaminated surface waters and groundwaters and wastewater. These water supplies are now a valuable part of a sustainable water supply; however, advanced treatment with advanced oxidation processes (AOPs) is typically needed to address trace contaminants in these supplies. This paper will address the following questions: 1) What is the best AOP technology for a given application? 2) Are there oxidation byproducts of concern? 3) What is the best peroxide quenching method? 4) How cost competitive are AOPs?

Today, advanced oxidation processes (AOPs) is considered as a key and effective method for environment preservation from pollutions. In this study , advanced photochemical oxidation processes using O3/H2O2 and O3/H2O2/UV systems were investigated batch photolytic reactor in lab-scale for the degradation of bisphenol A (BPA). In ozone generator source, air, as of the initial instrument feed, changes to ozone after electrical action and reaction. The UV irradiation source was a medium-pressure mercury lamp 300 W that was immerse in the wastewater solution with in 1.5 liter volume reactor. The reaction was influenced by the pH, the input concentration of H2O2, the input concentration of BPA, ozone dosage, chemical oxidation demand (COD) and UV irradiation time. Results showed that at initial bisphenol A concentration of 100 mg/l will completely degrade after 60 minutes by using O3/H2O2 in the pH range from 9.8 to 10 and by adding UV, it will happen in less than 36 minutes in the pH range of 3 to 10. The O3/H2O2/UV process reduced COD to 75 percents.

Polyvinyl alcohol (PVA) is an emerging pollutant commonly found in industrial wastewater, owing to its extensive usage as an additive in the manufacturing industry. PVA’s popularity has made wastewater treatment technologies for PVA degradation a popular research topic in industrial wastewater treatment. Although many PVA degradation technologies are studied in bench-scale processes, recent advancements in process optimization and control of wastewater treatment technologies such as advanced oxidation processes (AOPs) show the feasibility of these processes by monitoring and controlling processes to meet desired regulatory standards. These wastewater treatment technologies exhibit complex reaction mechanisms leading to nonlinear and nonstationary behavior related to variability in operational conditions. Thus, black-box dynamic modeling is a promising tool for designing control schemes since dynamic modeling is more complicated in terms of first principles and reaction mechanisms. This study seeks to provide a survey of process control methods via a comprehensive review focusing on PVA degradation methods, including biological and advanced oxidation processes, along with their reaction mechanisms, control-oriented dynamic modeling (i.e., state-space, transfer function, and artificial neural network modeling), and control strategies (i.e., proportional-integral-derivative control and predictive control) associated with wastewater treatment technologies utilized for PVA degradation.

Abstract AOPs can be modeled at several different levels, depending on the amount of kinetic information and computer resources available, and the purposes to which the results will be applied. Integration of the simplified rate equations gives the most information and provides the best check of the model with actual laboratory data. Even the simplest method discussed, comparison of target compound disappearance with oxidant consumption, is considerably better for optimization purposes than is simply comparing contaminant disappearance curves between experiments run under different conditions.
