Course Instructor: Mr. David H. Paul
David Paul is the President of David H. Paul, Inc., a high-tech water treatment training and
consulting firm. David has over 35 years of experience in advanced water treatment. He has
published over 160 technical articles and papers. He has created and administers a 4,000 page,
college-accredited correspondence training program, 4-semester on-campus programs and
extensive on-line training programs in high-tech water treatment. He has trained over 12,000 water
treatment professionals worldwide. He holds a B.S. degree in biology and an M.S. degree in
microbiology. His experience includes 2.5 years as an operator, 1 year as a first level supervisor and
8.5 years as the manager of a huge membrane and distillation water treatment plant followed by
over 25 years of training and consulting at hundreds of high-tech water treatment systems
including brackish water and seawater municipal drinking water RO plants and industrial high-
purity systems.
Course Description:
The reverse osmosis (RO) Technology has been utilized for seawater and brackish water industrial and drinking water applications since
the 1970s. Both seawater and brackish water RO systems, particularly those operating on surface water sources, still may have severe
problems that cost a lot of money. These are common problems that everyone involved with RO systems should know. This course is
for those new to RO technology and those with experience. What is taught are the common problems that occur, and the effective
ways to solve these problems. The information is based upon the instructor’s 36 years of operating, managing, training and consulting
experience at hundreds of plants.

Course Instructor: Dr. Boris Liberman
Dr. Boris Liberman is a graduate of the Institute for Scientific Research in Water Supply, Moscow
(Ph.D.) and the Civil Engineering Institute Rostov-on-Don, USSR (B.A. and M.S), and has been in
the field of desalination for over 20 years.
For the last 20 years Dr. Liberman has been employed by IDE Technologies Ltd., Israel, currently as
CTO and Vice President, Membrane Technology, managing the design, construction and
commissioning of various membrane desalination plants of which some are the largest in the world.
Dr. Liberman is the developer of the Pressure Centre desalination concept, Direct Osmosis Cleaning,
16” membranes arrangement in a vertical position, and IDE PROGREEN desalination technology, and
is responsible for conceptual design of IDE's RO projects.
IDE’s Ashkelon SWRO Desalination Plant, designed and commissioned under Dr. Liberman’s
leadership, won the GWI Desalination Plant of the Year award in 2006.
Dr. Liberman holds several granted patents in the field of reverse osmosis desalination, as well as
pending applications in said field as well as in the field of power generation from osmosis and has
written and presented dozens of articles in conferences around the world, and written papers that
have been published in leading industry magazines.
Dr. Liberman has been in the field of desalination for over 20 years, and currently serves as the CTO
and VP Membrane Technology for IDE. He is responsible for several technological breakthroughs
including the Pressure Centre concept, the patented Direct Osmosis Cleaning, and other patent
pending innovations such as 16” membranes in a vertical arrangement and IDE PROGREEN
