Direct Osmosis for Reverse Osmosis Fouling Control: Principles, Applica- tions and Recent Developments
Reverse osmosis (RO) has been widely applied in various water and wastewater treatment processes as a promising membrane technology. However, RO membrane fouling is a global issue, which limits it operating flux, decreases water production, increases power consumption and requires periodical membranes Cleaning-in-Place (CIP) procedure. This may result in low effectiveness, high cost and adds en...
متن کاملForward osmosis: Principles, applications, and recent developments
Osmosis is a physical phenomenon that has been extensively studied by scientists in various disciplines of science and engineering. Early researchers studied the mechanism of osmosis through natural materials, and from the 1960s, special attention has been given to osmosis through synthetic materials. Following the progress in membrane science in the last few decades, especially for reverse osm...
متن کاملFouling Prediction in Reverse Osmosis Processes
In recent years, membrane separation processes have successfully established footholds in all areas of chemical separations. Semipermeable membranes are now enhancing and even replacing long-time standard techniques such as distillation and solvent extraction (1). They are also being used in the preparation of purified chemical and biological products as well as the treatment and recovery of ma...
متن کاملReverse Osmosis and Ultrafiltration
Membrane processes have been successfully employed for treatment of a large number of industrial effluents. Reverse osmosis (RO) and ultrafiltration (UF) are versatile separation and purification tools for the process industries. Both of these techniques are based on the ability of pressure-driven filtration membranes to separate multi-component fluids based on molecular size, shape, and chemic...
