Combining coagulation, softening and flocculation to dispose reverse osmosis retentates

Water treatment: Combining reverse osmosis and ion exchange

Water treatment in today’s modern world requires highly technical, high performance separation products to achieve increasingly stringent treated water qualities, or to provide the lowest cost of water production. However, more than one separation technology is often applied to achieve the demanded quality. This development was a main consideration for y offering process designers a combination...

A Novel Photovoltaic Powered Reverse Osmosis with Improved Productivity of Reverse Osmosis and Photovoltaic Panel

With the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. Domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. The novel concept of photovoltaic powered ...

Reverse 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...

Forward Osmosis as a Pre-treatment to Reverse Osmosis

This paper presents some aspects of forward osmosis coupled with reverse osmosis using a recirculating draw solution, to produce desalinated water or for dewatering/concentrating a feed stream, with some data provided from a number of operational sites. Many of these aspects are applicable to other osmotic processes and provide an insight into where they may be appropriately considered. A compa...
