Influent state
Screening
Manual or automated screening removes debris at the plant entrance and protects the stages that follow.
Gross solids and non-biodegradable debris are intercepted before biological treatment.

Biological wastewater treatment
Sewage moves through screening, anaerobic and aerobic treatment, clarification with a real Return Activated Sludge loop, disinfection and a verified destination.
RAS return
Settled state
Anaerobic treatment
Solids separate by specific gravity while anaerobic bacteria begin breaking down the sewage without added oxygen.
Two anaerobic phases support digestion, middle-cut transfer and denitrification from nitrate to nitrogen gas.
Biologically active state
Aerobic bioreactor
Fine-bubble aeration supplies oxygen so aerobic bacteria can continue treating the water.
Fixed-bed cross-flow media supports colonisation, oxygen transfer, hydraulic retention, BOD reduction and nitrification.
Clarified state
Clarification + RAS
Biological solids settle into a sludge blanket. Activated sludge returns to the first anaerobic stage to seed the incoming flow.
The Return Activated Sludge loop recirculates mature biomass and supports denitrification; final design remains site-specific.
Treated state
Disinfection
The final stage reduces harmful microorganisms before the verified reuse or discharge route.
The source site identifies ozone as the primary method, with UV or chlorination selected where requirements call for them.
Outcome state
Reuse or discharge
Treated water follows the destination confirmed by the design and water-quality requirements.
Potential non-potable destinations include irrigation and dust suppression; all claims require project-specific verification.

What each stage needs to answer.
The interactive view is paired with semantic content so the process remains usable without motion or JavaScript.
What enters?
Source, flow pattern, loads, contaminants and variability.
What changes?
The physical, chemical or biological action at the stage.
What is protected?
The downstream process, people, environment or asset.
What proves it?
Sampling, monitoring and the project-specific target water quality.
