Optimal Design & Operation Of RO Systems

3-Day Seminar

Information Packet

Seminar Cost ‐ $2,997 USD (Early Bird Discounts May Apply)  Seminar Length – 3 days (8 hours per day)  Seminar Description If you’re an Original Equipment Manufacturer, you want to design the best RO system you can THAT WILL SELL.  If you’re a plant engineer, you want to identify a good, cost‐effective RO system. If you’re a buyer, you want the lowest capital cost for an RO system.  If you’re a manager, you want to purchase an RO system that gives you the water you need at the lowest life‐cycle cost, which includes the lowest capitol AND O & M costs.    If you operate and/or maintain an RO system, you want a system that runs all the time without a lot of time consuming problems.  But unless you have knowledgeable people specifying systems you will likely receive a low‐bid system that costs fewer capital dollars but much more in O & M dollars over the 20+ years of the life of the plant.  Not good!  Unless you know the features of a good design, you won’t understand how to operate the plant in the most cost effective manner.  By understanding good design, you can troubleshoot problems more quickly and effectively.  This seminar condenses the experience that David Paul has learned since 1977 including: 

• 2.5 years as an operator of RO systems • 1 year as a shift supervisor of RO systems  • 8 years as the manager of a $120 million USD huge RO water treatment facility • 22+ years of training and consulting at hundreds of RO water treatment facilities  

 This seminar will take you step by step through the features of good RO unit design, pretreatment and operation.  This includes evaluating the scaling, fouling and chemical attack characteristics of different feedwaters, to good RO/NF unit designs to good operation. You will learn things that you will not get anywhere else.  You can also consider this a consultant level understanding of RO systems seminar which is valuable both from a design standpoint and from and operations/troubleshooting standpoint.  Who Should Attend This seminar provides valuable, practical knowledge to anyone wanting to understand the most important features of a well designed and operated RO system including: 

• Design engineers • Plant engineers • Service technicians • Buyers • Plant Supervisors or Managers • Operating & Maintenance Personnel 

    

Why You Should Attend So you know the difference between low-bid, high-fouling, pain-in-the-pocket-book (and other places) RO systems and ones that can operate with the lowest life-cycle costs and fewest problems.

What You’ll Receive

• 3 8-hour days of interesting, step-by-step, easy-to-understand, practical RO training • A highly illustrated workbook • Break refreshments
