Keep Chemical Costs Under Control

Dechlorination of wastewater effluent is common practice in many wastewater treatment facilities throughout the U.S. Strongly reducing sulfur compounds are used to eliminate chlorine residuals that might prove toxic to fish in the receiving stream. Because residual chlorine discharge limits are often very close to zero, water quality monitoring residual values to comply with regulations has become very difficult, and controlling residuals at values between zero and 10 or 20 parts-per-billion is often not achievable.

To meet stringent discharge limits, the sulfite or bisulfite used for dechlorination is added in slight excess, providing a small sulfite residual to ensure complete dechlorination. The Q46S/66 provides operators with a reliable tool for maintaining a small sulfite residual while reducing excess chemical consumption due to overfeed.

Because measuring the sulfite ion in solution is relatively difficult, the Q46S/66 Monitor takes a different approach to the measurement, employing a unique gas-phase method to continuously monitor sulfite 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 acidic solution, the sulfite ion is converted to sulfur dioxide gas. The mixed sample flows into a special chamber where the sulfur dioxide is stripped from the sample. A gas conditioning module prepares the gas sample for measurement before contact with a special SO2 gas sensor designed for the system. Sensor signals are amplified and displayed on a large-format, backlit LCD display in the Q46S electronics unit.

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.
