 On-line Ammonium and Nitrate Ion Selective Measuring
WEFTEC Booth 30140 Hall B
The VARiON® Plus Family:
On-line Ammonium and Nitrate Ion Selective Measuring
- In-situ combination sensor for ammonium and nitrate
- 2 compensated parameters measured simultaneously
- Calibration- free with Automatic Compensation
- Continuous measurement with long term stability
- Economical and cost effective
WTW’s VARiON® Plus ion selective online sensor enables the continuous, concurrent measuring of both nitrogen parameters ammonium and nitrate. Through factory calibration and long stability of electrodes (up to 18 months durability) manual calibration is now redundant.
The advantages of the new VARiON® System are unmatched. The combination sensor can deliver reliable measurements of ammonium and nitrate at the same time. The high stability of the electrodes and the redundancy of calibration efforts make it an economical solution for a 24/7 operation in direct process.
WTW’s VARiON® Plus ion selective online sensor technology features four flexible electrode connection slots, two for the concurrent measuring of both nitrogen parameters: ammonium and nitrate. The third slot accommodates a compensation electrode for measuring the ions that could potentially falsify the measurement result, i.e. potassium (for nitrate) or chloride (for ammonium). One of the two nitrogen parameters can therefore be dynamically compensated to achieve a more precise measurement. The fourth slot is dedicated for the reference electrode.
The digital data output is transmitted instantly to the IQ Sensor Net, making the ammonium and nitrate parameter real-time for rapid, online process control. Combined with an efficient control strategy, reduction of the oxygen input during sludge activation can be achieved. Direct savings will be realized by reducing the energy consumption required for the oxygen pumps.
When a single parameter measurement is required, the new VARiON® Plus Nitralyt® Plus and Ammolyt® Plus is the best choice where nitrate and ammonia is measured individually with dynamic compensation.
