Coagulation-Ultrafiltration Systems in Water and Wastewater Treatment

A systematic techno-economic framework for hybrid CUF process design

Hybrid coagulation-ultrafiltration processes offer cost-effective water treatment, yet scattered reasoning, confused nomenclature and fragmented research complicate system selection and design. Coagulation-Ultrafiltration Systems in Water and Wastewater Treatment brings order to this literature across fifteen chapters, presenting a unified, configuration-by-configuration synthesis that connects coagulation chemistry, floc physics, membrane transport, and fouling dynamics to performance prediction and process economics.

Coverage spans advanced hybrid CUF configurations including oxidation-coagulation-UF, ultrasound-assisted, biologically enhanced, photocatalytic, gas sparged, ballasted electro, magnetic, micro-nano bubble-mediated systems, and more. Each configuration is evaluated with explicit integration of transport equations, cake-layer mechanics, TMP evolution, and energetics alongside design-facing decision criteria. Recent developments with practical examples, case studies, and illustrations ground each chapter in real-world operational context.

The book also features:

• Learning outcomes and review questions with numerical problems in each chapter for structured self-assessment and deeper understanding
• A companion solutions manual providing detailed step-by-step solutions along with tips and strategies for contextualized comprehension
• Analysis of novel coagulants, floc regrowth and floc dynamic protection layers, guiding readers to visualize complex interfacial fouling evolution
• Configuration-level financial feasibility tools enabling engineers to compare hybrid CUF systems based on performance and cost trade-offs
• Coverage of integration strategies and techniques that extend CUF capabilities for emerging contaminant removal applications

Designed for civil, chemical, and mechanical engineers, environmental scientists, water resource managers, advanced students, and for all those who toil at the uneasy frontier between theory and practice, this book delivers an authoritative framework for selecting, designing, and implementing hybrid coagulation-ultrafiltration systems, and lays bare the promise and peril of advanced hybridization with integrated physicochemical auxiliaries, showing not merely what may be added but when, why, and at what cost!
