Where to use the Diamond range

How it works

1. The wastewater from the house flows into the aeration chamber of the diamond tank for treatment.
2. The central aeration chamber empties the sewage into the bottom of the outer clarifier chamber.
3. Air is released at the bottom of the draft tube through a disc plate air diffuser. An upward flow of process fluid draws settled solids through the draft tube to discharge at the surface of the aeration chamber. The design of the draft tube ensures complete mixing of oxygen with the sewage. Oxygenation allows aerobic organisms that biologically degrade wastewater contaminants, to grow.
4. Gravity causes the aerated solids to settle back down to the bottom of the tank where they are again drawn up through the draft tube. As raw sewage enters the aeration chamber it displaces biological solids from the aeration chamber to the clarifier. Still conditions in the clarifier allow digested solids to settle at the base and return to the aeration chamber.
5. The clarified (treated) effluent flows slowly up through the clarifier and over a weir that extends around the circumference of the tank. The effluent collects in an outer trough where it is discharged through a 110mm pipe connection.
6. A scum baffle located inside the overflow weir, prevents floating solids from passing over the weir.
