Course Objectives

Gain an understanding of the techniques of boiler water treatment and analysis.

Course Description

This course has been designed to provide a broad overview of the water treatment process necessary for most industrial uses and for the power generation industry in particular. The course will discuss in detail the various options and parameters as regards water treatment.

Who Should Attend

This course is primarily aimed at those in the Power Generation industry who require an understanding of the techniques of boiler water treatment and analysis. The course would also benefit any process engineer/chemist employed in the any of the modern industrial processes that use demineralised water.

Pre-Requisites

All Attendees should have a sound chemical and engineering background.

Course Outcome

At the end of this course you will be able to understand boiler water treatment and analysis.
