Phase 3: chemical wastewater treatment In this phase of wastewater treatment, chemical processes are utilized for wastewater treatment. To this conclude, chemical compounds are employed to realize legally prescribed water regular values.
Wastewater is considered thoroughly clean soon after secondary treatment, but tertiary treatment returns it to an even larger excellent for release in safeguarded waters.
Just after screening, the water is aerated (supplied with air) by passing it around a number of steps to take in oxygen from your air.
