Dr. Dhawan has worked in the membrane technology field since 1972, when he started commercializing and manufacturing membranes and membrane systems.  He worked closely with Dr. Sourirajan, the inventor of the first commercial reverse osmosis membranes.

Dr. Dhawan set up a membrane division in Ontario, Canada and headed this division of the company until 1980. From 1980 to 1983, Dr. Dhawan headed the Sales and Marketing of Fluid Systems, with worldwide marketing and market development responsibility.
