Graf Wastewater Treatment Tank with additional dosing options from 5PE to 18PE in one or two tank systems. 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. 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 occurs twice per day, each lasting 12 hours. Additional dosing can be included to achieve desired effluent quality i.e., phosphate dosing.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Graf UK is consulted before specifying.
