Full Description

This 9 person One2Clean Plus with pumped outlet sewage treatment plant by Graf offers an efficient solution to off-mains effluent treatment. This product has an innovative design, as only one tank is required with one process chamber.

Installation is quick and easy, as no concrete is required, simply use a gravel base and backfill.

This tank has an ultra-quiet operation, making it the ideal choice in domestic properties.

There are 3 stages to the treatment process:
1. aeration
2. settling phase and
3. clear water extraction

This ensures that the sewage is treated to a high standard, and is suitable to be discharged safely 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 minimal sludge to be removed, and only one pumping process is required, meaning maintenance costs are kept low.

- Up to 99% efficiency
- Low-energy consumption
- Free commissioning available
- 3 stage treatment process
- Quiet operation
- Free delivery
- Easy installation
- No concrete required

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.
