Multi Effect Desalination, MED Water Desalination Method, Operation, Startup and Trouble Shooting

Introduction

The development of desalination plants in recent years and the estimation of increased trends in desalination directions are increasing the interest in understanding desalination plants currently in use. The cost of desalinated water is still high for many people, so there is a need to learn how to reduce costs as well as understand how the techniques work before trying to develop new technologies.

Objectives

    The participants will have a good idea of the following subject

    • describes the subject of Multi-Effect Distillation (MED).
    • The technology, which belongs to the field of evaporation techniques, is explained in detail and different
    • the pant designs.
    • Design equations are also given based on heat balance, flow configuration and heat transfer mechanisms in the system.
    • also Related subjects such as
      • the energy needed, the energy source,
      • environmental issues,
      • operational technologies
      • The most common problems are also explained.
      • A comparison with other techniques and recommendations for future improvements are given.

Training Methodology

The course will be conducted along with workshop principles with formal lectures, case studies and interactive worked examples. Relevant case studies will be provided to illustrate the application of each tool in an operations environment. Each learning point will be re-enforced with practical exercises. There will be ample opportunities for discussion and sharing experiences.

Who Should Attend?

This course is aimed at engineers, scientists and technologists involved in the planning, management and operation of water desalination systems and also for manufacturers, consultants, designers, researchers, and water personnel.
