Full Description

This 7 person One2Clean sewage treatment plant by Graf offers a straight-forward solution to off-mains effluent treatment. One tank is required with one process chamber, which maximises efficiency.

There are 3 stages to the treatment process; aeration, settling phase and clear water extraction. This ensures that the sewage is treated to a high standard, and is suitable to be discharged at the end of the process.
The sewage enters the tank and is filtered using an aeration process. The sludge then settles at the bottom of the tank, and the remaining clear water is extracted and drained in a soakaway or other drainage method. This means that there is incredibly little sludge to have removed, and only one pumping process is required, meaning minimal maintenance costs.

Benefits:
- Up to 99% efficiency
- Low-energy consumption
- Free commissioning available
- 3 stage treatment process
- Quiet operation
- Free delivery

There is also a double sludge storage volume which means that more time can pass before a sludge removal is required. The tank is 100% resistant to corrosion which means that its lifespan is optimised, as it is resistant to the elements.
