Full Description

This 14 person One2Clean Plus sewage treatment plant by Graf offers a smart and simple solution to off-mains effluent treatment. This treatment plant is supplied with a pumped outlet, meaning it has greater flexibility regarding where it can be installed.

The One2Clean Plus range comes with a superior control panel, keeping you well informed as to the status of your system.

Installation is quick and easy, as no concrete is required, simply use a gravel base and backfill. Holiday mode can be automatically activated by under load detection and flood alert.

There are 3 stages to the treatment process; aeration, settling phase and clear water extraction. 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.

- Up to 99% efficiency
- Low-energy consumption (46 kwh per person per year)
- Free commissioning available
- 3 stage treatment process
- Quiet operation
- Free delivery
- Easy installation
- Extended warranty

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.
