This course provides an introduction to water treatment using reverse osmosis and covers the equipment required and their function to give an engineer/technician a strong foundation on how to use and maintain a Water Treatment facility. This course is divided into four sections, starting with the fundamentals of water treatment using reverse osmosis or septic systems. The second section covers how water is prepared for water treatment based on the feedwater into the system. The third section covers how water is processed post water treatment to prepare the water for end-use. The final section will explore how to conduct maintenance on the water treatment components, calibrate and interpret readings from indicators within the system.
