HOW IT WORKS
Detailed treatment flow for compliant, reusable water.
Process design follows globally recognized treatment logic: solids capture, primary settling, biological conversion, advanced polishing, and controlled reuse/discharge.
01
Integrated Stage
Preliminary Intake & Screening
Influent first passes through screening and grit removal to capture rags, plastics, sand, and abrasive particles that can damage pumps and downstream equipment.
Functional Impacts
- Protects pumps, blowers, and membranes
- Stabilizes downstream hydraulic performance
02
Integrated Stage
Primary Sedimentation
Primary clarifiers slow flow so settleable solids sink and floatables are skimmed. In conventional systems, this stage often removes around 50-70% suspended solids and 25-40% BOD.
Functional Impacts
- Reduces solids loading before biology
- Lowers aeration energy demand in later stages
03
Integrated Stage
Biological Treatment (Activated Sludge/MBR)
Aerobic microorganisms degrade dissolved and fine organic pollutants. Where needed, membrane bioreactors improve solids separation and support compact footprints with high effluent quality.
Functional Impacts
- Targets BOD/COD reduction
- Supports nutrient management pathways
04
Integrated Stage
Tertiary Polishing & Disinfection
Filtration and final disinfection barriers polish the effluent to meet discharge or reuse objectives, reducing pathogen risk and improving consistency for non-potable reuse applications.
Functional Impacts
- Filtration for low turbidity
- UV or chemical disinfection barrier
05
Integrated Stage
Reuse & Resource Recovery
Treated water can be routed for irrigation, industrial process support, or controlled discharge, while sludge streams can be stabilized for safer handling and recovery pathways.
Functional Impacts
- Supports circular water strategies
- Enables lower freshwater abstraction

Reuse Potential
UNEP estimates around 320 billion cubic meters per year of untapped wastewater reuse potential, showing the scale of recoverable water resources.
UNEP via UN-Water facts summary
5x
Energy Opportunity
UNEP data indicates wastewater systems can potentially generate about five times the energy needed for treatment when recovery is integrated effectively.
