Effluent Monitoring into Sensitive Waters

Chelsea Technologies’ Tryptophan-like fluorescence (TLF) systems enable in situ or in-line real-time reporting of bacteria within effluent from Waste Water Treatment Works into sensitive waters, such as waters close to bathing waters and aquaculture sites. These monitors detect fluorescent proteins that are found within sewage and slurry. The principle behind the measurement is the excitation of Tryptophan-like fluorescence at UV wavelengths, which is highly sensitive and has been shown to correlate with bacterial contamination.

These systems can also be configured to monitor Biological Oxygen Demand (BOD), which can be used by water utilities to inform on how the bacterial removal systems within a Waste Water Treatment Works are performing.

Chelsea solutions

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

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

Portable systems are light weight, easy to operate and designed to take into the field to measure bacteria concentrations within the rivers into which the effluent is released.

These systems provide real-time display and logging of bacteria necessary for water quality monitoring.  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’ UviLux fluorometer, which is small, 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.
