Reverse Osmosis (RO) Desalination Process, Operation and Troubleshooting

Introduction

Course Objectives:

This is a skill-building course designed to teach participants what is Reverse Osmosis and how does it work, what are the main components of any RO plant, how can you run safely your plant and what are remedy action needs to be taken to restore your plant efficiencies and performance. In addition, the participants shall learn how to operate and maintain their plants in the most cost-effective way.

Who Should Attend?

O & M managers, production managers mechanical & electrical engineers, chemists, RO operators, maintenance engineers, maintenance technicians, QA & QC engineers
