Expert Troubleshooting of RO/NF Systems

3-Day Seminar

Information Packet

Seminar Cost ‐ $2,997 USD (Early Bird Discounts May Apply)  Seminar Length – 3 day (8 hours per day)  Seminar Description Nearly every RO system experiences performances problems sometime during its operating life.  If you’ve never seen a particular problem before, however, you may not respond quickly enough to solve the problem at an early, reversible stage.  DHP has provided troubleshooting services to hundreds of clients.  DHP has seen many, many different problems.  This seminar provides expert level training.  One or more DHP instructors will teach you the troubleshooting tips and techniques that they have amassed through a combined nearly 100 years of experience.  If you’re a service technician or consultant, you need to be able to troubleshoot and resolve the most complex problems a client is having.  If you’re a facility manager, lead operator or plant engineer you need to be able to troubleshoot and resolve problems quickly so you can operate your facility at the lowest life‐cycle cost.  Original Equipment Manufacturers (OEMs) frequently run into problems during startup of new systems and must troubleshoot and resolve problems as quickly as possible.    The truth is, when there is only one problem occurring, there is a good chance that experienced and somewhat trained plant personnel can solve the problem.  When there are multiple problems going on at the same time, this will likely take an expert level of troubleshooting skills to resolve.  This seminar will take you step by step through DHP’s troubleshooting methodology from A to Z.  You will learn things that you will not get anywhere else.  Who Should Attend People who should attend this seminar are: 

Business owners  General managers  Sales representatives 

Managers   Service technicians/installers
