Water/Wastewater
Efficient and optimised biological wastewater treatment by dynamic control with the new System 282/284 controller
Sep 14 2016
Increase efficiency of the biological treatment of your plant and reduce the amount of oxygen consumption by installing the new controller System 282/284, a D.O. and a NH4 sensor. The costs of ownership will further be reduced, as the optical D.O. sensor FDO® 700 IQ is calibration free and the NH4 ISE sensor VARiON® 700 IQ is low in maintenance.
With the combination of D.O. and NH4 measurement, the control strategy can be changed from a time-based to a dynamic control and thus substantially improved. The oxygen supply will always be sufficient - and it will be stopped as soon as ammonia has dropped below a certain level.
Both parameters can be displayed on the System 282 controller, and with the four-channel System 284, even up to four sensors can be connected. All controllers are equipped with an internal data logger and a USB interface for easy saving of data, system configurations and for software updates.
