Membrane based point-of-use drinking water treatment system

Abstract

Membrane-based PoU water treatment systems have proved to be a milestone in PoU water treatment eliminating various shortcomings of other water treatment technologies. The main driver of membrane-based PoU water treatment systems is that it works without the addition of chemicals, with relatively low energy usage, and easy and well-arranged process conductions. With improved technology, there is an inevitable need to understand the basic operational parameters, design and maintenance of membrane-based PoU water treatment systems to eliminate the repercussions of lack of knowledge. The book describes membrane-based PoU water treatment systems and is divided into eight chapters. Chapter 1 explains the sources and contaminants in drinking water and the importance of removing these contaminants. Chapter 2 describes different units, advantages and limitations of the conventional water treatment plants and various PoU water treatment technologies. Chapter 3 covers components of membrane-based PoU water treatment systems. Chapter 4 describes the effective designing of various components of the membrane-based water treatment systems to make them more economical and practical. Modelling, simulation, and process optimisation of membrane-based PoU water treatment systems are included in Chapter 5. Chapter 6 includes operation and maintenance aspects, including pre- and post-treatment units. Techno-economic aspects of membrane-based PoU water treatment systems are elucidated in Chapter 7. Chapter 8 elaborates on national and international protocols for certification and system evaluation.
