Multi Stage Flash (MSF) Desalination Plant Simulator Operation

Course Description

This course provides participants with practical hands-on training in operating Multi Stage Flash (MSF) desalination plants. Participants will learn the fundamentals of plant operation and be familiar with the concept of control room operation using a distributed control system (DCS). All operations are performed using a MSF plant simulator.

In the first part of the course, participants will perform a startup from cold condition using the MSF plant simulator, starting from plant auxiliary systems, system filling, chemical system, up to brine warmup. In the second part of the course, participants will learn the operating procedures for treating distillate in the Remineralization Unit in order to obtain potable water. The course also covers the types and functions of chemicals used to make drinking water reach the acceptable limits of minerals.
