In wastewater systems sulphides can cause damage to concrete structures and can contribute to odour problems in water treatment facilities.
The ATi innovative A15/81 Dissolved Sulphide Monitor simplifies and improves the process of measuring sulphides by taking a totally unique approach.
Traditionally, measuring the sulphide concentration in water has been done by the use of analysers employing selective ion electrodes (SIE) for sensors.
While providing adequate sensitivity, SIE based systems require frequent zero and span adjustments to retain measurement accuracy, making them relatively expensive to maintain.
Rather than using an SIE sensor, the ATi A15/81 employs a polagraphic H2S gas sensor that is isolated from the sample.
The result is a system that can operate continuously on many types of water and wastewater streams with minimal adjustment.
As sulphide measurements are often made in poor quality samples, fouling of the analytical system is a major concern.
The ATi innovative system overcomes this problem by ensuring that the sensor never comes into contact with the sample.
Only the gas stream containing the stripped H2S reaches the sensor.
This creates a system that will continue to function regardless of the quality of the sample.
Monitoring sulphides in water with the ATi A15/81 provides extremely high measurement sensitivity.
For example, monitoring samples down to low parts-per-billion levels is easily achievable.
In addition, because the gas sensor is very stable, monthly zero and span checks are all that is required, eliminating any necessary maintenance costs. Request a free brochure from Analytical Technology ...
