How it works

• Untreated waste enters the tank via the inlet on the side of the tank.
• The wastewater falls directly into the biological zone where the treatment is taking place, this allows the micro-organisms to start the breakdown process without delay.
• Compressed air is sent to the treatment plant via the control panel. This air is initially used for aeration through the diffuser.
• The aeration process is intermittent to achieve the best treatment performance.
• With a One2Clean 2-tank system, the level of water between the tank is kept level by a pipe linking the tanks near the base. Also, during aeration, a small proportion of the compressed air is being feed to a siphon, which returns some activated waste to the primary tank.
• Aeration is then stopped to allow for the activated waste to sink to the bottom of the tank.
• Compressed air is then sent to the plant again to extract the cleaned water near the surface, via the red air-lift. This water passes through a sampling point before leaving the plant, where samples can be taken to confirm the quality of effluent.
• The above process is then repeated.
