Principles of Membrane Processes in Liquid Separation fills a gap in membrane science by focusing on fundamental principles rather than materials or applications. It covers three key areas: the fundamentals of retained particles and their impacts in membrane processes, state equation and generic cost model for reverse osmosis desalination modeling and optimization, and mechanisms of water and ion transport across membranes. The text provides theoretical foundations while offering practical insights for improved membrane process design and operation, serving both as an educational resource for students and a reference for engineering professionals.

• Addresses fundamental principles of membrane processes in liquid separation rather than materials or fabrication methods.
• Provides advanced modeling approaches and optimization techniques for reverse osmosis desalination that enable more efficient process design and operation.
• Resolves longstanding conceptual challenges in membrane science, including proper characterization of concentration polarization and improved boundary conditions for ion transport equations.
