The ATI Q46H/83 allows for continuous monitoring of low permanganate concentrations, allowing operators to adjust chemical feed rates and achieve target values.
Potassium Permanganate (KMnO4) 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.
The Q46H/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 to iodine (I2), and the resulting I2 is stripped out of solution and measured using an I2 gas sensor. This “gas phase” measurement technique eliminates MnO2 sensor fouling, resulting in a system capable of providing long term reliability.
The Q46H/83 Permanganate monitor consists of two main components, an electronic display unit and a chemistry module. The chemistry module contains sample and reagent pumps, sample handling systems, and the gas sensor that provides the final measurement. An inlet overflow assembly attached to the bottom of the chemistry module is where the inlet sample line and drain line are connected. Sample inlet flows of 250-100 ml./min. are recommended to keep system response time to a minimum. Reagent bottle holders are supplied so that reagents can be wall mounted below the chemistry system.

With an average rainfall of only 12.5 inches per year and a population that's growing faster than the country's , Arizona is a state that faces unique challenges, especially when it comes to clean, safe water. The Water Quality Division of the Arizona Department of Environmental Quality (ADEQ) protects and enhances public health and the environment by monitoring and regulating drinking water. And although they make use of the latest scientific methods and new technology, given the current state of Arizona's water system, they also rely upon low-tech equipment and cooperation from members of the community to monitor water quality in the state. Team members in the Groundwater Protection Program work to sample, test and characterize groundwater quality in all 51 of Arizona’s basins.Read More
William Anderegg, assistant professor of biology at the University of Utah, has spent years studying drought-stricken trees all over the world. As climate change is expected to cause increased drought severity in the future, the work of Anderegg and his colleagues becomes increasingly important. In a previous interview for the Environmental Monitor , Anderegg found that a tree’s hydraulic safety margin was the best indicator of whether a tree would survive drought. The hydraulic safety margin is an expression of how the tree reacts under drought conditions, where there is very little water being pulled up the tree’s transport system and air is being pulled up instead. “It’s like a heart attack for the tree,” he noted.Read More
You've probably heard of the Four Corners region of the United States; that's where the corners of Arizona, New Mexico, Utah and Colorado meet at one point. These same four states are also part of the Colorado River Storage Project (CRSP), which began to change the face of the American West in 1956, enabling the population explosions in places like Phoenix and Los Angeles to continue thanks to usable water. Glen Canyon Dam is 220 meters high and 480 meters wide, and this massive structure has changed this section of the Colorado River all the way to Lake Mead dramatically. It has also increased low-flow magnitudes, decreased peak flow magnitudes and volumes and caused fluctuations in daily discharge levels that the area relies upon for generation of hydroelectric power.Read More
