coastal monitoring Applications

Measurement of water quality in coastal regions and estuaries is critical in the characterization of hypoxic ‘dead zones’ as a result of nutrient loading and algal blooms in the water bodies. Sediment loading analysis through turbidity measurement is also important for coastal trend identification and modeling. Hydrolab and Sea-bird Coastal offer a variety of multiparameter water quality instrumentation and nutrient sensors for long-term coastal applications.

The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these organisms at the entrance and exit of the canal, generating alarms in the presence of toxic substances.

The UviLux BOD Indicator enables in-situ, real-time, reporting of BOD within both natural water systems and water processing plants. The monitor detects fluorescent proteins that are inherent within sewage and slurry and provides an output in BOD equivalent units. The principle behind the measurement is the excitation of Tryptophan-like fluorescence within UV wavelength band, which has been shown to correlate with both BOD and bacterial contamination. With complete flexibility of deployment methodology, the UviLux BOD Indicator can be applied to both water supply and water recovery processing plants. For water supply processing, the UviLux BOD Indicator can be applied at the front end to the water intake to provide alarm of any contaminated water entering the plant. Applications within Waste Water Treatment Works can include monitoring of effluent levels at the final outflow point (into rivers and coastal areas) as well as the primary, secondary & tertiary stages, the data potentially feeding into energy saving systems to optimise process performances. The CTG UviLux BOD Indicator in-situ fluorometer can also be used within pipe and channel networks to test for incidences of black water and grey water cross-over.
