Monitoring Algae for Water Treatment

Chelsea Technologies’ algae monitoring systems enable in situ or in-line real-time reporting of algae within abstracted waters entering Water Treatment Works. As well as Chlorophyll a, these in situ fluorometer systems can detect cyanobacteria, such as Phycocyanin and Phycoerythrin, which are often associated with algae groups of a toxic nature.

The detection of algae in stored water systems, such as reservoirs, and abstracted waters from rivers assists in the planning and informs decisions on water abstraction in relation to natural algae blooms that regularly occur throughout the year. Knowledge of concentrations of algae within the water can assist in assessing Geosmin formation & determining loading into water processing plants, informing on taste & odour issues & filter control.

Chelsea solutions

Chelsea Technologies offer both stationary in-line and portable algae monitoring systems.

In-line monitoring stations systems can be easily fitted within Water Treatment Plants, either connected into a piped system or monitoring within a water trough.

Portable systems are also available which are light weight, easy to operate and designed to take into the field to measure algae concentrations directly within rivers, reservoirs and lakes and compared directly against measurements taken within the in-line systems at the Water Treatment Plant.

These systems provide real-time display and logging of key algae parameters necessary for water quality monitoring and the management of a water treatment process. Useful Red, Amber, Green threshold levels can be easily set up, and the display provides both graphical and numerical formats.  These systems include the Chelsea Technologies’ UniLux or TriLux fluorometers, which are miniature, low power and easily integrated to other sensor network systems. As well as being very sensitive, these fluorometer sensors are optimised to provide low noise results.

Just launched this  month is the new VLux MiniSonde –   a miniature, cost effective, multi-parameter sensor providing robust data collection for either UV or visible fluorescence monitoring. With integrated corrections for multiple environmental parameters, models are suitable for monitoring BTEX, PAH, Tryptophan and Algae.
