  • The main operating cost for Reverse Osmosis plants is the cost for electricity. The energy recovery system supplied with the plant is therefore very important. A separate section below discusses energy recovery. Because we are asked so often, I have also included a section on the Operating Cost, as well as some Frequently Asked Questions.

  • This book is a companion volume to two published in 2011 by INTECH titled “Desalination, Trends and Technologies” and “Expanding Issues in Desalination”. The term “desalination” used in this series is in the broadest sense of the removal of dissolved, suspended, visible and invisible impurities in seawater, brackish water and wastewater.

  • The production process is based mainly on the use of natural fibers-primarily of wood but with significant reliance on non- wood fibers in the developing world. Apart from this a large number of other inputs also affect the production of paper & its products. The predominantly contributing factors are; chemicals, water, fillers and energy which play a significant role in quality and cost effective production of paper products. This reliance on harvested products makes the sector an...

  • Electrokinetics is a subject that has been at the core of numerous fundamental advancements in the field of colloid science for over a century. Electrokinetics is a self-contained body of science that has led to spectacular applications in separations, characterization of surface properties, manipulation of colloidal materials, and facilitation of fluid transport in microchannels. For instance, electrophoresis is one of the common techniques for separation of biological macromolecules (such as proteins).

  • Interfacial systems are frequently encountered in a large variety of phenomena in biology and industry. A few examples that come to mind are adsorption, catalysis, corrosion, flotation, osmosis, and colloidal stability. In particular, surface films are very interesting from a cognitive point of view. Surface science has a long history. For many years, natural philosophers were curious about interfacial phenomena because it was quite clear that matter near surface differs in its properties from the same matter in bulk...
