Permanganate (MnO4-) is a strong oxidizer used in the water industry for reduction of organics in raw water. It is also used for control of zebra mussel problems at raw water intake structures. Continuous monitoring of low permanganate concentrations allows operators to adjust chemical feed rates and achieve target values. Chemical feed problems that result in either too little or too much residual can be quickly identified and corrected. Monitor MnO4- without Sensor Contamination!

Continuous monitoring of permanganate in treated water presents sensor contamination issues. When permanganate reacts with organics or other reducing materials in solution, manganese dioxide (MnO2) is formed and readily plates out on sensing electrode surfaces. The resulting deposits degrade the measurement and can be difficult to clean. The Q46/83 eliminates this problem by employing a measurement method in which the sensor never comes into contact with the sample. In operation, water containing permanganate is mixed with pH buffer and potassium iodide solutions. Permanganate oxidizes the iodide...

FEATURES Gas Phase Sensing. Measurement is made without contact between sample and sensor, eliminating the potential for sensor fouling. Standard Method. Permanganate is measured using iodometric measurement after reaction of the sample with buffer and potassium iodide. Analog Output Options. Two isolated 4-20 mA outputs are standard. One output is programmable for PID function. Three Control Relays. Relays are programmable for setpoint, deadband, and time delay. Digital Communications. Communication options for Profibus-DP, Modbus-RTU, or Ethernet-IP. Clear Display. Back-lit large LCD display...
