On-site treatment
The treatment uses electrochemical oxidation plus anaerobic digestion. The treatment line descends from Caltech research. Zero discharge is a design intent.
Collection
Screening separates large solids before treatment.
Anaerobic digestion
Organic matter breaks down without oxygen, as in this treatment process.
Electrochemical oxidation
Electrochemical oxidation is the other part of the Caltech treatment line.
Reuse for flushing
Treated water is intended for flushing inside the unit. The design aim is no effluent discharge. Water quality is confirmed per site.

Circular Economy Principles
Discharge and site rules
On-site treatment
The container treats wastewater inside the unit. It is designed not to discharge effluent.
Local discharge rules
What a site may do with treated water depends on the installation and the rules that apply there.
Operator records
Service notes, alerts, and maintenance stay with the team that runs the unit.
Engineering pack
