2 About the IDA Desalination Academy The IDA Desalination Academy aspires to increase knowledge that leads to innovation but that is only the start. Attending the Academy creates a platform for sharing ideas, building new connections and exchanging insights as participants enhance their skills and expand their professional development. At the IDA Desalination Academy, we focus on not only increasing practical skills and knowledge but putting these advances in a broader context. Everyone involved in today s desalination industry plays an important role in shaping the world s water solutions for future generations. We are committed to encouraging innovation, thinking outside the box and fostering excellence. That is the lasting role of the IDA Desalination Academy.

3 How to Correct the Biggest BWRO & SWRO Problems May 31, 2014 Instructor: t Mr. David Paul

4 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 includingbrackishwater andseawater municipaldrinkingwater RO plantsandindustrialhigh and highpurity 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.

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 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 desalination technology. Course Description: This course will discuss the design of Mega Size RO Desalination Plants including the Pressure Center in Ashkelon, Hadera and Soreq Plants and the 16 Vertical membrane arrangement in Soreq plant and will cover: Green design of RO plants and desalination without chemicals; new design of continuous backwash filter; recovery of osmotic power from SWRO brine, and osmotic power generation (Ocean River); and challenges in osmotic power generation, and ways to solve them.
