sewage treatment plant monitoring Applications

  • Sewage Treatment Plants and Flow Sensors for Industry Application

    In sewage treatment plants, flow sensors are primarily installed for internal reasons. Ultrasonic flow meters are used to control the flow velocity in partially filled and fulfilled pressurized pipes, specific plant components, for leak detection or to control the use of additives. International regulations such as the EU-Directive for handling municipal waste water require flow metering for a continuous surveillance of waste water flow. Defective flow monitoring in sewage-treatment plants can therefore influence their operation, but there can also be legal or environmental consequences.

  • Final effluent monitoring for wastewater treatment industry

    Industry and municipal waste-water (sewage) treatment plants have had to respond to environmental legislation such as the Urban Waste Water Directive, IPC, IPPC and now the EPR (Environmental Permitting Regulations). As successive legislation becomes more stringent, discharge consents have been progressively tightened, and the need for self-regulation has become more important. As a consequence, on-line instrumentation has been installed throughout waste-water industry to continuously to provide final effluent monitoring and perform water analysis for key consent parameters.

  • Real-time In-situ Effluent Monitoring

    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.

  • Water accountability portable monitoring for solving flow rate mystery

    The Glen Walter Sewage Collection System was built to service 1080 customers in 1989. At the time the population was 850 but by 1995 the sewage treatment plant had already reached capacity. Shawn Killoran took over the Operations Manger position in 1999 and, along with the Mayor and Council, he immediately had concerns about the excess flow.
