Continuous online measurement of water quality parameters.
Water polluted by discharges impacts directly on the health of humans, as well as having secondary socio-economic consequences on populations.
ADASA achieves rapid detection of pollutants by monitoring physical-chemical parameters that indicate water quality and protect the environmental state of natural water sources. We have extensive experience in handling potentiometric, polarographic and optical technologies.
Tracking sensors also optimise processes in wastewater treatment plants, aquaculture facilities and any sectors where water plays a significant role.
Potentiometric sensors measure the potential difference between two sensors (indicating sensor and reference sensor) immersed in a solution. The indicator sensor provides the potential that is generated as a function of the concentration of specific ions. In contrast, the reference sensor has a known, stable potential, independent of the ions present in the solution. Potentiometric sensors are widely used for the measurement of pH, ORP and conductivity.
Polarographic sensors, used to measure dissolved oxygen, have a gas-permeable membrane that separates them from water. The oxygen that passes through the membrane reduces, creating a current proportional to the oxygen concentration that the sensor can measure. These sensors are inexpensive but require frequent maintenance. They need a constant sample as they consume the oxygen that diffuses through the membrane.
Optical sensors measure different properties of light, depending on the parameter to be determined:
At ADASA, we select the most suitable sensors for each installation, depending on the characteristics of the water bodies. We offer bespoke solutions adapted to needs and can integrate existing systems into our multi-parametric solutions, such as:
Our solutions for the continuous measurement of physical-chemical parameters are all easy-to-handle, have low operating costs and are environmentally friendly. There’s no need to use reagents, and they don’t generate harmful waste.
