GRAF One2Clean Sewage Treatment Plant 5PE | G50000

The GRAF One2Clean is a highly efficient, single-tank wastewater treatment system that uses advanced SBR (Sequencing Batch Reactor) technology to achieve up to 99% pollutant removal. Engineered to meet EN12566-3 standards and fully CE certified, this compact unit delivers exceptional effluent quality and is future-proofed for evolving regulatory requirements.

• Cover Options – Comes with a pedestrian-grade lid as standard. A vehicle-rated lid (up to 3.5 tonnes) is also available and requires the Maxi Dome extension for proper load distribution.

• Outdoor Controller Cabinet – For installations where the control panel cannot be sited indoors (e.g., >20m distance from the tank), a lockable kiosk is available.

With energy consumption as low as 46 kWh per person annually and minimal sludge production, the One2Clean is an eco-conscious and cost-effective solution for domestic off-mains wastewater treatment. It includes a self-cleaning sampling chamber, and thanks to its plug-and-play design, no on-site electrical wiring is required.

The system is compatible with granular backfill on dry installations and is groundwater stable up to the tank's midline. GRAF UK offers free commissioning through an accredited service provider, with an optional 3-year technology warranty when commissioning and servicing are handled by approved partners.
