Forward Water Osmosis
Forward Osmosis - The Introduction
Forward Osmosis is the natural process of osmosis, which has been observed for centuries. The very first documented observation of osmosis was in 1748 by Jean-Antoine Nollet. In 1867 the word “osmosis” was coined by Rene Joachim Henri Dutrochet, whereafter the process was perfected by Moritz Traube after having invented selective precipitation membranes. This invention also created a technique of measuring the osmotic flow.
Forward osmosis is also an automatically occurring process, and does not require any additional hydraulic energy like reverse osmosis does. In this process, the draw solution is controlled for a specific amount and quality of concentration. Control over the draw solution ensures that unwanted dissolved solutes are avoided by water trading into the draw solution. This process has become very popular and gained a lot of popularity during the last few years due to all of its advantages in comparison to the reverse osmosis process.
