Water Treatment Methods

INTRODUCTION

Water treatment in our industries has remained a big challenge due to its high cost. Some industries are not familiar with cost effective methods and use millions every year. Due to the challenge in sustainability of these methods, some give up and end up releasing untreated water to the environment. This is not permitted by the law and other regulatory bodies and hence they end up facing the full force of the law.

 The course will equip the learners with the knowledge on how to choose the right water treatment technique and the ability to find the right balance between health & safety and financial considerations.  This will help in attaining sustainability of any water treatment as water treatment is compulsory when regulatory compliance is required, whereas voluntary water treatment can result in process optimization with ultimate reduction in costs and improvement in our quality of life. This training course by Gerizim Consortium will focus on the optimization of water treatment in different applications.

COURSE OBJECTIVES

By the end of this training course, participants will be able to:

• Assess their needs and water resources available
• Select appropriate water treatment techniques
• Apply selected water treatment techniques and optimize their application 
• Develop relevant monitoring regimes to ensure effectiveness of treatment
• understand the technical restrictions in the application of water treatment techniques

TARGET GROUP

This training course is suitable to a wide range of water treatment professionals but will greatly benefit:

• Maintenance personnel in the process industries
• Institutions of higher learning
• Regulatory authorities (hygiene and health & safety inspectors
• Water treatment engineers/Plant engineers
• Facility management companies personnel
• Project Managers.

COURSE DELIVERY METHOD

This training course is presented face to face using proven adult participatory andragogy techniques like;

• Participatory Lecture Method
• Power point presentation and Animated graphic presentations
• videos
• Group discussions
• Brain storming
• Questioning and Answering
• Role play
• Group work
