Sewage treatment is very important in our society. Nevertheless, treatment plants have many important functions. The sewage treatment plant is also known as the domestic waste treatment plant.
Originally, the process involves cleaning sewage that is released from domestic and commercial sources. You can find the best sewage treatment plant in Australia.

Generally, this does not include cleaning the waste that is released exclusively from dirty sources, for example, heavily industrial companies or factories of nuclear reactor coolants.
In modern sewage treatment plants, there are two main stages: primary, and secondary.
- Primary: The purpose of this last phase is to make the water as clean as possible before re-entering the environment. Typically, this is achieved by artificial or man-made natural filter systems. Sometimes any phosphorus or nitrogen is found in excess in the treatment.
- Secondary: In the second stage the main aim is normally to take out as many biological contaminants as possible. The secondary treatment is the stage at which the largest technical differences within sewage treatment can occur. This is because there are a number of methods in which biological contaminants can be reduced in wastewater.
This is a common mistake: the function of a plant is to make the water cleaner, but it's not clean enough to drink. It could be used in irrigation.
