Membrane Filtration for Wastewater Recovery

Whereas the total quantity of water on this planet is more or less fixed, its quality is deteriorating, because we have been contaminating it for thousands of years, with little concern for the consequences. Drinking water regulations continue to increase water quality standards, and industrial and commercial activities are requiring higher quality water in many …

Reverse osmosis process

Reverse osmosis (RO) is a process that is commonly employed for desalination of seawater. RO systems leverage asemi-permeable membrane to remove ions, molecules and unwanted contaminants and particles (salt in the case of desalination) from water. In a u-tube with unsalinated water on one side, salinated water on the other side, separated by a semi-permeable …
