3. Dr. Al Samadi
The inventor of several processes listed below. The objective has been to design advanced, cost-effective
membrane-based technologies to purify water, treat municipal and industrial effluents and minimize and/or
eliminate membrane concentrates, thus enabling complete water recycling and reuse and achieving Zero Liquid
Discharge (ZLD). Over the past two decades, Dr. Al Samadi has developed, patented and commercialized a
number of advanced membrane-based processes, including the following:
