Optimize aeration control
In combination with the optical sensor for dissolved oxygen (FDO® 700 IQ), the aeration on a wastewater treatment plant can be optimized in a highly efficient way. With the oxygen sensor, the concentration of dissolved oxygen can be controlled. In such case, the duration of the nitrification process is controlled by a fixed time. This strategy is called static time based control. By adding an ISE sensor for ammonia and nitrate, this time based control can be changed to a dynamic control. In that case, the nitrification process can be stopped as soon as the ammonia level reaches the level of consent.
