Overview of a Pool Plant System

In later sections of the course, we’ll be going into some detail about the main components of a pool plant system. For now, though, we need a basic overview. So first, look at the diagram of a typical swimming pool. Then, click on the ⓘ symbols for more information on the various components.

Main Components (in sequence)

1. Strainer basket(s)
2. Pump(s)
3. Filter(s)
4. Heat exchanger

Chemical Injection Points

1. Coagulant – after the pumps, prior to filter(s) but after auto chemical monitoring sample point.
2. Disinfectant – can be prior to or after filter(s) if no UV system fitted but always after UV if fitted.
3. Acid (pH correction) – usually after the heat exchanger.

Some of the diagrams in courses and textbooks depict the system you would have in an ideal world. But in the real world of pool plant operations you might need to operate an old, possibly neglected and not well-designed treatment system.

The slides show photos of a treatment system for a hotel pool. Click on the blue icons for more detail. They might help you recognise and identify some of the same components in your own plant room.

Here’s a filtration system that’s just been installed. As you can see, there are two filters in this system. The heat exchanger and backwash sight glass can also be seen.
