The Two-Electrode System Amperometric Ozone Sensor Is Used For All Water Treatment

Water treatment effect monitoring: Ozone is a strong oxidant widely used in water treatment processes, especially in drinking water, industrial water, wastewater treatment, etc. Ozone can effectively kill pathogenic microorganisms in water, such as bacteria, viruses and algae, and can oxidize organic pollutants, odor substances and color in water. Therefore, monitoring the ozone concentration in water helps to ensure the effect of water treatment.

Safety and health considerations: Although ozone has a significant improvement effect on water quality, high concentrations of ozone itself may be harmful to human health and the environment. Excessive ozone concentration in water may be toxic to the human body, especially if ozone is left in drinking water. Therefore, monitoring ozone concentration can ensure that it is within a safe range and prevent excessive residue.

Ozone consumption rate monitoring: During water treatment, ozone consumption will be affected by water quality, such as organic matter, ammonia nitrogen or other chemicals in water. By monitoring the ozone concentration in water, the consumption of ozone can be evaluated, and the dosage can be adjusted to ensure the effective use of ozone and avoid waste.

Environmental regulation: Ozone is an important disinfectant in the water treatment process, especially in areas with strict environmental protection requirements. Monitoring the ozone concentration in water can ensure compliance with regulations and environmental protection standards. For example, the US EPA and other regulatory agencies sometimes require monitoring of ozone residuals to ensure its disinfection effect on water quality and avoid negative impacts on the ecological environment.

Water treatment technology optimization: By regularly testing the ozone concentration in water, the operation of the water treatment system can be optimized, and the ozone addition and contact time can be improved, thereby improving disinfection efficiency and reducing operating costs. Monitoring data can help identify potential problems or optimize system configuration.

The two-electrode system amperometric ozone sensor 10.1, used for all water treatment, including seawater. Such as tap water, deionized water, RO-reverse osmosis membrane system has mechanical resistance, and the membrane system has strong resistance to surfactants.

The functional characteristics of the ampere film ozone sensor include high sensitivity and fast response, which can accurately measure the ozone concentration in water. Its advantages are strong anti-interference ability, suitable for various water quality environments, and long service life. It is suitable for drinking water and industrial water treatment to ensure water quality safety.
