GRAF One2Clean 10 Sewage Treatment Plant

GRAF One2Clean sewage treatment plant – 10 population – gravity outlet

A reliable wastewater disposal system is the one2clean.  You will be able to take responsibility for the timely disposal of your waste water, while taking care of your budget and the environment.  One2clean is an advanced development of the proven SBR wastewater treatment technology, with considerable advantages in terms of operating costs and safety.

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.
