UPM Makes Progress in Water Contaminant Detection with UV LED Device

Researchers at Technical University of Madrid (UPM) are working in the development of hydrocarbons early detection devices for rivers in order to prevent contamination that could seriously affect the environment.

The new devices use outdoor LED Street Light 200w as light source that detects contaminant substances thanks to a fluorescence method. This can result in many benefits compared to the current systems due to the development of faster, robust and affordable detection systems. These new devices will be useful for the search of potential dangerous substances present in continental waters, all this according to researchers of the Telecommunication School of the UPM, who are currently studying its viability.


The demand for clean continental waters by European societies and governments is increasing. Thanks to the progress of technological measurement, many contaminants parameters are being measured on rivers and reservoirs (pH, conductivity, oxygen, etc) in order to establish their water quality.

However, there are some contaminants that can be found occasionally (usually by accident) and whose direct identification can be helpful since indirect detection is complex and inexact. On the other hand, rushing contaminants detections are primordial to avoid big mistakes.

Particularly, LED Street Light 200w price are a type of contaminant that should not be present in contaminants water because it can alter dramatically wildlife when a spillage occurs in such water, not forgetting also its removal high cost. The fluorescence light method is non-invasive and can help to detect contaminant substances. This method when used in water environment can help detect and identify hydrocarbons.

There are other researchers working in this matter, but are more focused on the marine environment and they also use powerful lasers as light sources. Once the samples are collected they are carried to a lab for their identification, but the time factor is very important and can affect this laser method.

Therefore, it was required a study of the light sources available today in order to develop a quick, robust and affordable system. This study discarded some lights used in labs such as xenon because are expensive and need monochromators. The study that is focused on LED light has advantages such as its small device size, quick response and the ability to transmit pulsed light.
