High-Sensitivity Sulfide Monitoring

Sulfides can be found naturally in well water and can build up in wastewater collection systems due to anaerobic conditions frequently found there. In addition, sulfides are used in mercury removal processes and are frequently found in tanning wastes. In drinking water systems, sulfides cause taste and odor problems. In wastewater systems, sulfides cause damage to concrete structures in collection systems and contribute to odor problems in treatment facilities.

Measurement of dissolved sulfide concentrations has been done primarily by the use of analyzers employing ion-selective electrodes (ISE) for sensing. While providing adequate sensitivity, ISE-based systems require frequent zero and span adjustments to maintain measurement accuracy. Because of this, most ISE-based monitoring systems are relatively expensive and require frequent service.

Due to measuring sulfides in the solution being relatively difficult, the Q46S/81 Monitor takes a different approach to the measurement, employing a unique gas-phase method to continuously monitor sulfide without contact between the sensor and the water sample. In operation, a small amount of sample is pumped into the system and mixed with acid. In an acidic solution, the sulfide ion is converted to hydrogen sulfide gas The mixed sample flows into a special chamber where the hydrogen sulfide is stripped from the sample. A gas conditioning module prepares the gas sample for measurement before contact with a special H2S gas sensor designed for the system. Sensor signals are amplified and displayed on a large-format, backlit LCD display in the Q46S electronics unit.

Features

  • Improved method for measuring sulfides in solution
  • No contact between sensor and water sample

Market Applications

  • Drinking Water Treatment

    Drinking water treatment facilities have the critical job of producing a safe supply of high-quality drinking water. Complex operational processes demand the highest flow meter accuracy and reliability, as well as long-term stability and a low cost of ownership. Badger Meter water treatment solutions meet the challenge, assisting utility customers with increasing compliance levels, protecting treatment assets and providing opportunities for process optimization using predictive analytics.

  • Industrial Pre-Treatment

    Industrial pre-treatment is a crucial stage in the water cycle, occurring before wastewater enters municipal treatment facilities. It involves the removal of contaminants, pollutants, and other harmful substances from industrial wastewater streams to meet regulatory standards and protect the environment. This process typically includes physical, chemical, and biological treatment methods tailored to specific industrial processes and pollutants. By effectively pre-treating industrial wastewater, we can safeguard water quality, prevent damage to treatment infrastructure, and ensure the overall health of ecosystems downstream.
