"Abstract:"Emphasizing new technologies that produce clean water and energy from the wastewater treatment process, this book presents recent advancements in wastewater treatment by various technologies such as chemical methods, biochemical methods, membrane separation techniques, and nanotechnology. It addresses sustainable water reclamation, biomembrane treatment processes, advanced oxidation processes, and applications of nanotechnology for wastewater treatment. It also includes integrated cost-based design methodologies. Equations, figures, photographs and tables are included within the chapters to aid reader comprehension. Case studies and examples are included as well"-"

"This volume contains many state-of-the-art applications for the development of new materials and technologies. It discusses computer-based engineering tools which are widely used and related to the simulation, evaluation of data and design processes. For example, modern joining technologies can be used to fabricate new compound or composite materials, even composed of dissimilar materials. Such materials are many times exposed to harsh environments and must reveal specific properties. Technologies in this context are mainly related to the transportation technologies in their wider sense. This means automotive and marine technology, i.e., ships, amphibious vehicles, docks, offshore structures, and even robots. Typically, finite element and finite volume methods are used in the context of engineering simulations and this volume highlights their importance."

"This book offers a comprehensive collection of micro electrical discharge machining (EDM) processes, including hybrid processes. It discusses the theory behind each process and their applications in various technological as well as biomedical domains, and also presents a brief background to various micro EDM processes, current research challenges, and detailed case studies of micro-manufacturing miniaturized parts. The book serves as a valuable guide for students and researchers interested in micro EDM and other related processes."

"This book evaluates water management together with energy use. The strong effects that the release of emerging pollutants such as endocrine disruptors (EDCs), pharmaceuticals and personal care products (PPCPs) have in wastewater reuse applications are examined, as well as the need to optimize the energy consumption in wastewater treatment.

"Industri batik menghasilkan limbah cair dalam volume besar dengan kandungan organik yang tinggi. Zat warna pada limbah cair batik sukar diolah dengan proses biologis sehingga diperlukan pengolahan lebih lanjut untuk mengurangi beban pencemar sebelum dilepaskan ke lingkungan. Penelitian ini bertujuan untuk mengamati kinerja dari masing-masing metode kavitasi ultrasonik, ozonasi, dan kombinasi ozonasi dan kavitasi ultrasonik untuk mengolah limbah cair batik yang terlebih dahulu diberikan pralakuan koagulasi-flokulasi dengan koagulan Polyaluminium Chloride (PAC). Variasi yang dilakukan pada penelitian adalah intensitas gelombang ultrasonik (20%, 30%, dan 60%) serta pH limbah (4, 7, dan 10). Pada penelitian ini didapatkan bahwa metode kavitasi ultrasonik dengan intensitas ultrasonik 20% menghasilkan penyisihan COD, TSS, dan warna (Pt-Co) masing-masing sebesar 65,59%, 91,51%, dan 93,41%. Pada proses ozonasi dengan pH 4 diperoleh penyisihan COD, TSS, dan warna (Pt-Co) masing-masing sebesar 70,51%, 94,35%, dan 96,10%. Adapun metode kombinasi ozonasi/kavitasi ultrasonik dengan pH 4 dan intensitas ultrasonik 20% menghasilkan penyisihan COD, TSS, dan Pt-Co tertinggi, yakni sebesar 77,02%, 95,15%, dan 94,88% secara berturut-turut.

The batik industry produces large volumes of liquid waste with high organic content. Wastewater treatment is needed to reduce pollutant load before being released into the environment. This study aims to observe the performance of each ultrasonic cavitation, ozonation, and a combination of both methods to treat batik wastewater, which is first given a coagulation-flocculation pre-treatment with Polyaluminium Chloride (PAC) coagulant. Variations made in the study are the intensity of ultrasonic waves (20%, 30%, and 60%) and the wastewater's pH (4, 7, and 10). In this study, it was found that the ultrasonic cavitation method with an ultrasonic intensity of 20% produced COD, TSS, and color (Pt-Co) removal of 65.59%, 91.51%, and 93.41%, respectively. In the ozonation process with pH 4, COD, TSS, and color (Pt-Co) removal were obtained at 70.51%, 94.35%, and 96.10%, respectively. The combined ozonation/ultrasonic cavitation method with a pH of 4 and an ultrasonic intensity of 20% produced the highest removal of COD, TSS, and Pt-Co by 77.02%, 95.1%, and 94.88%, respectively."
