What is the Diploma in Membrane Technologies and Reverse Osmosis?
The Diploma in Membrane Technologies and Reverse Osmosis
Prepares you to design, operate and optimise reverse osmosis systems and other membrane technologies for seawater. You will study the fundamentals of transport through membranes, pre-treatment, the design of racks, stages and passes, control of fouling and scaling, energy recovery and emerging technologies, always with a practical, plant-focused approach.
Key advantages
- A plant focus: From the physical principle to the day-to-day running of a reverse osmosis rack.
- Design with software: Use of membrane system projection tools.
- Operation and maintenance: Troubleshooting, cleaning and data normalisation.
- Energy efficiency: Energy recovery devices and strategies to cut consumption.
- Case study: Designing and troubleshooting a seawater reverse osmosis plant.
Programme highlights
- Understand membranes: Master the fundamentals of transport through membranes.
- Design systems: Size reverse osmosis racks, stages and passes.
- Control fouling: Apply effective pre-treatment and cleaning.
- Save energy: Optimise the plant’s energy consumption.
- Boost your career: Open doors to desalination plants, engineering firms and equipment manufacturers.
- Train in the technology that makes modern desalination possible.
