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:

U.S., Canadian and Australian Patents:

High Recovery Membrane Purification Process:

• U.S. Patent No. 5,501,798, March 26, 1996

• Canadian Patent No. 2,186,963, November 1998.

• U.S. Patent No. 6,113,797, September 2000.

• Enhanced High Recovery Membrane Processes (August 2008, U.S. Patent Pending)

• Single stage and 2-stage High Recovery Membrane Purification Process

• (May 2008, Australian Patent Pending)

High Water Recovery Single Stage Membrane Process:

U.S. Patent No. 6,461,514, October 8, 2002.

Pre-treatment Process for Membranes:

U.S. Patent No. 6,416,668, July 9, 2002.

Acid Purification and Recovery

• Recovery of Carboxylic Acids from Plant Effluents (U.S. Patent No. 5,635,071, June 1997).

• Waste Acid Recovery Process, U.S. Patent No. 5,082,645, January 1992.
