Advanced Pool Care Guide.

If you are new to swimming pools, read the basic pool maintenance manual first. CLICK HERE.

This guide is a little more advanced and covers water treatment and chemical usage in much greater detail and is more suited to professional pool people who have an understanding of the terminology and the chemicals in use. There is a lot of information here, so it has been broken down into chapters.

Basic requirements of Swimming Pool Water Treatment

1. Water Circulation
2. Flow Rate - explanation of turnover time and the importance of
filtration and circulation
3. Dilution - addition of fresh water

Main Treatment Processes

1. Filtration and filter Backwashing - how it works, what it does
and why.
2. Flocculation - how it works and why it is necessary. Types of
flocculation currently available
3. Water Disinfection - its purpose
