ABSTRACT
The most successful application of the reverse osmosis process is in the production of drinking water from seawater. This process is known as seawater desalination and is currently producing millions of gallons of potable water daily in the Middle East. Typical applications of ultrafiltration processes are the treatment of electroplating rinse water, the treatment of cheese whey, and the treatment of wastewater from the pulp and paper industry. There are several types of membranes for gas and vapor separation. Palladium is known to absorb a large amount of hydrogen gas. One mol of palladium can absorb 6 mol of hydrogen. The properties of polymeric materials are similar to those of rubber, at temperatures above the glass transition temperature. Polymers in this state are called rubbery polymers.
