How is wastewater treated?

Wastewater is treated in several stages in order to purify it. First, the wastewater is sent to sewage treatment plants, where coarse impurities such as stones or branches are removed. This is followed by mechanical purification, where sand and other particles are filtered out. The wastewater is then biologically purified: Bacteria decompose organic substances and nutrients in the water. In a further purification stage, pollutants such as phosphates or nitrogen compounds are also removed. Finally, the purified water is disinfected before it is discharged back into rivers or lakes. This process ensures that the wastewater has no harmful effects on the environment and can be safely reused.

How does wastewater treatment work?

Wastewater treatment takes place in several steps to remove pollutants from the wastewater. First, the raw wastewater is collected and coarse impurities such as waste or sand are filtered out.
