Water Chemistry

Points to consider.

The information given in this module, follows guidelines issued by Australian Standards, Queensland. Government Health Water quality guidelines for public aquatic facilities and General Industry parameters. This is always Billabongs policy.

There is no definitive set of water chemistry for all pools.

Every pool is a separate entity.

There is a marked difference in chemical demand for a domestic pool and for a commercial pool. We will in most cases be discussing commercial pools, domestic requirements are less demanding, but generally allied.

Queensland Health water chemistry protocols are essential for maintaining water quality and safety in the region. They provide guidelines for monitoring and managing water sources to protect public health, the environment, and promote sustainable water practices.

Training Topics

Let’s dive into the essential topics related to swimming pool chemistry. Maintaining proper water balance and understanding the key chemical components are crucial for keeping your pool clean, safe, and enjoyable. 

Overview of a Pool

Let’s explore, an overview of swimming pools

Halogens (sanitisers)

Let’s explore the role of halogens as disinfectants. Halogens are a group of chemical elements that include chlorine, fluorine, bromine, and iodine. These elements exhibit unique properties that make them effective for disinfection purposes:

pH

Let’s dive into the importance of pH levels in swimming pools and how to maintain them for optimal water quality.

Total Alkalinity

Let’s dive into the importance of Total Alkalinity (TA) in swimming pool chemistry and how it contributes to maintaining water balance.

Calcium Hardness

Let’s dive into the importance of calcium hardness in swimming pool chemistry. Calcium hardness refers to the total amount of dissolved calcium in your pool’s water. Here’s why it matters

Cyanuric Acid (stabiliser)

Cyanuric acid (CYA), also known as chlorine stabiliser or pool conditioner, plays a critical role in maintaining your swimming pool. Let’s explore why it’s essential and how to manage it effectively.

Totally Dissolved Solids

Total Dissolved Solids (TDS) play a significant role in swimming pool water quality. Let’s dive into what TDS is, why it matters, and how to manage it.

L.S.I. Saturation Index

The swimming pool saturation index, also known as the Langelier Saturation Index (LSI), is a critical component of pool water chemistry. Let’s explore why it matters and how to maintain it for a safe and healthy swimming environment.

Testing 

Testing your pool water is crucial for maintaining water quality. Remember, accurate testing leads to a clean and safe swimming experience!

Chemical Parameters

Maintaining proper swimming pool water chemistry is essential for water quality and swimmer comfort. Let’s explore the key chemical parameters:

Pool Turnover

Swimming pool turnover is crucial for maintaining water quality and ensuring a safe and enjoyable swimming experience. Let’s explore why it matters
