Graf One2Clean Sewage Treatment Plant Process:
- Wastewater enters the One2Clean tank through a side inlet, flowing directly into the biological zone where treatment begins as microorganisms break down waste.
- Aeration starts with compressed air diffusers to optimize treatment, then pauses to allow settled waste to sink.
- Cleaned water near the surface is extracted with compressed air, passing through a sampling point for quality checks before discharge.
- This treatment cycle runs twice daily, each lasting 12 hours.
- Sludge build-up at the tank’s base should be removed according to the manufacturer’s recommendations, with disposal by a registered waste carrier.
Features & Benefits:
- Single-tank system with one chamber
- Low energy consumption
- No mechanical or electrical components in wastewater
- Minimal sewage sludge production
- Clear, odour-free treated water
- High manufacturing standards for durability and corrosion resistance
- Suitable for installation in groundwater
- Easy maintenance with a self-cleaning sampling container
