in situ sensors offer a promising solution for the real-time detection of alterations in water. Hydroquo+, a company with extensive experience in monitoring water quality, has developed monitoring systems that use physical-chemical parameters to detect pollutants and protect natural water sources.
Through potentiometric, polarographic, and optical technologies, Hydroquo+ sensors can quickly detect changes in water quality, allowing for a rapid response to water pollution. This not only helps protect human health but also has positive socio-economic consequences for affected populations.
In addition to detecting pollutants, Hydroquo+ tracking sensors can be used to optimize processes in wastewater treatment plants, aquaculture facilities, and other industries where water plays a significant role. Hydroquo+ commitment to protecting water sources and promoting sustainable practices makes them a leader in water quality monitoring.
In water quality monitoring, optical and polarographic sensors are commonly used to measure different parameters. Polarographic sensors are often used to measure dissolved oxygen, with a gas-permeable membrane separating the sensor from the water. When oxygen passes through the membrane, it reduces and creates a current proportional to the oxygen concentration. While inexpensive, these sensors require frequent maintenance and a constant flow of water to function properly.
Optical sensors, on the other hand, measure different properties of light depending on the parameter being determined. For dissolved oxygen, fluorescence extinction measurement is used. The sensor membrane contains a luminescent compound that emits red light when excited with blue LED light. The more dissolved oxygen in the sample, the more red fluorescence is quenched. The intensity and lifetime of the luminescence are inversely proportional to the oxygen concentration.
Turbidity can also be measured with optical sensors, through the refraction of light. The light emitted by the LED is scattered proportionally by the turbidity of the sample, and the amount of light that reaches the detector is inversely proportional to the turbidity of the sample.
Finally, pigments such as chlorophyll and phycocyanin can be measured using the fluorescent properties of the pigments. When excited at a given wavelength, the pigments emit light at a longer wavelength, proportional to the number of pigments in the sample. The use of optical sensors in water quality monitoring offers a reliable and efficient method for measuring various parameters.
