Primary Treatment

Settling tanks remove suspended solids and oils.

Screening

Removes large solids like plastics, rags, and debris.

Biological Treatment

Microorganisms break down organic pollutants. Common technologies: MBBR, SBR, MBR.

Secondary Clarification

Separates treated water from sludge.

Tertiary Treatment

Advanced purification such as: Activated carbon, Filters, UV/Chlorine disinfection

Sludge Management

Collected sludge is dried and disposed safely.

Conclusion

A well-designed plant ensures safer water discharge, lower pollution, and improved system life.
