“…Dairy effluent can be treated in many ways including biological (ELLIS et al, 1992), electrochemical (Melo et al, 2020; Shahbeig et al, 2017), membrane technology (Shahbeig et al, 2017) and Advanced Oxidation Process (AOP) (Rad & Lewis, 2014). It contains high organic and harmful components which requires a special treatment process to reduce the environmental damage.…”

Dairy industry effluent will pollute the environment if not properly treated. In the present work, the feasibility of nonthermal plasma (NTP) for the treatment of dairy industry effluent is assessed. The effect of energy yield and plasma intensity on reduction of Chemical Oxygen Demand (COD) removal is investigated. Box–Behnken design (BBD) is employed to optimize the operating parameters such as initial pH (5–9), reaction time (4–8 h), effluent flow rate (10–90 ml/min) and applied voltage (20–30 kV) where COD and energy yield are taken as responses. The optimum condition for COD removal and energy yield is same with a pH of 9, effluent flow rate of 10 ml/min and applied voltage of 30 kVp‐p, whereas reaction time differs as 8 and 4 h, respectively. COD reduction of 52% indicates that NTP process is a promising technology for dairy effluent treatment.

“…This was due to the application of preozonation considerably reduces the membrane flux that could promote the filtrate properties of membrane [27]. In contrast, when applying a fenton as a post-treatment of membrane process, it does not give possible results in pollutant removal due to the formation of ion compounds during fenton reaction [28,29]. This present study aims to investigate the performance of synergisation of UV radiation with ozone/H 2 O 2 system in simulated and real dairy effluent.…”

The present study focused on the various advanced oxidation processes; Ozone, UV radiation, O 3 /H 2 O 2 , O 3 /UV, UV/H 2 O 2 and O 3 /UV/H 2 O 2 for treatability of dairy industry wastewater. With this aim, the trials were carried out in cylindrical reactor fortified with UV radiation and Ozone injection. Efficiency of the treatment process was evaluated considering Chemical Oxygen Demand (COD), lactose reduction and process parameters were determined to be reaction time, pH, circulation rate, and H 2 O 2 dosage. 32.5%, 35.2% , 25%, 83% COD and 40.6%, 43.6%, 38.2%, 80% lactose reduction efficiency were obtained under the operating conditions for O 3 /H 2 O 2 , O 3 /UV, UV/H 2 O 2 and O 3 /UV/H 2 O 2 processes, respectively. As per this outcome, UV/H 2 O 2 /O 3 process gave more than 65% of COD and 52.36% of lactose reduction efficiency than other hybrid processes. Optimum conditions for UV/H 2 O 2 /O 3 process (pH = 5, time = 180 mins, circulation rate = 50 mL/h and H 2 O 2 dosage of 0.5 mL) resulted in 88% of COD and 93.4% lactose reduction.

He has co-authored over twenty peer-reviewed scientific papers, several conference proceedings, chapters, and books. His research interests include advanced oxidation processes, advanced treatment of water and wastewater, waste minimization, water, soil and air quality, energy and resource recovery, water reuse, and heterogeneous catalysis. PrefaceAdvanced Oxidation Processes -Applications,Trends, and Prospects constitutes a comprehensive resource for civil, chemical, and environmental engineers researching in the field of water and wastewater treatment. The book covers the fundamentals, applications, and future work in Advanced Oxidation Processes (AOPs) as an attractive alternative and a complementary treatment option to conventional methods. This book presents state-of-the-art research on AOPs and heterogeneous catalysis while covering recent progress and trends, including the application of AOPs at the laboratory, pilot, or industrial scale, the combination of AOPs with other technologies, hybrid processes, process intensification, reactor design, scale-up, and optimization. The book is divided into four sections: Introduction to Advanced Oxidation Processes, General Concepts of Heterogeneous Catalysis, Fenton and Ferrate in Wastewater Treatment, and Industrial Applications, Trends, and Prospects.The first section provides the reader with a comprehensive introduction to AOPs, organic contaminants, current technologies, heterogeneous catalysis, mechanisms, and application in wastewater treatment. Fundamentals and general concepts of heterogeneous catalysis are the main focus of the second section, with particular emphasis on chemical kinetics and its application for wastewater treatment. Section 3 is focused on the use of Fenton and Ferrate as wastewater treatment methods; particular attention is given to fundamentals and applications of Fenton and Ferrate, followed by future research, guidelines on regeneration, and environmental impact. Finally, the book closes with a section on the application of AOPs in different industries, such as food and beverages, petrochemical, and flexographic printing; future trends and prospects are described, as well as a comprehensive case study of a solar photocatalytic plant, where the scale-up and optimization processes were covered from bench-and pilot-scale to full-scale operation.I would like to acknowledge the authors who collaborated with their research towards this book; their efforts and contributions are highly appreciated. I would like to thank both Ms. Maja Bozicevic and Mr. Edi Lipović, Author Service Managers, for their support during the editing and publishing process, as well as the partnership of IntechOpen and Knowledge Unlatched for fully funding and sponsoring this endeavour.To my wife, Liseth, my daughter, Victoria, and my entire family, with love.
