Sewage treatment is very essential in our society. This is an area that is often misunderstood if it is understood at all. Nevertheless, treatment plants have many important functions.
The sewage treatment plant is also known as the domestic waste treatment plant. Basically, the process involves cleaning sewage that is released from domestic and commercial sources. There are so many companies like Byjas that provide better information about sewage treatment plants in Sydney.

This generally does not include cleaning the waste, which is specially sourced from dirty sources, for example, heavily industrial companies or factories of nuclear reactor coolants.
Modern sewage treatment plants have three main stages: primary, secondary, and tertiary.
- Primary: In this first phase the waste materials are easily removed. The primary treatment is the stage at which the largest technical differences within sewage treatment can occur.
- Secondary: In the second phase the main objective is to exclude as many biological contaminants as possible. This is because there are many ways to reduce organic pollution in wastewater. It is said that microorganisms are commonly used to get rid of any unwanted elements.
- Tertiary: The purpose of this last phase is to make the water as clean as possible before re-entering the environment. This is usually achieved by artificial or man-made natural filter systems.
