    Water monitoring technology for nutrient monitoring

    Continuous monitoring of nutrient levels provides crucial information about daily, seasonal and event based changes in water quality conditions, and can be a strong indicator on the overall health of the water body.  In recent years, monitoring of nutrients has grown in importance as it has come to the forefront in regulatory compliance of water quality in many regions.

    Deionized Water Testing

    Years ago, high purity water was used only in limited applications. Today, deionized (Dl) water has become an essential ingredient in hundreds of applications including: medical, laboratory, pharmaceutical, cosmetics, electronics manufacturing, food processing, plating, countless industrial processes, and even the final rinse at the local car wash.

    Monitoring of raw water intake

    The Situation:

    Hydrocarbons in municipal water supplies,  including fresh water and desalination systems, are commonly limited to less than 1 part per million. Surface water from rivers, lakes, or the sea with marine traffic, nearby pipelines, or regular flooding can be contaminated by hydrocarbons. Freshwater treatment systems can be damaged by hydrocarbons or allow them to pass through undetected. Desalination systems using reverse osmosis (RO) membranes can be irreversibly damaged by the presence of hydrocarbons. Continuous monitoring of water source intakes can prevent system contamination and subsequent damage.  Accurate, low maintenance monitoring systems such as the TD-4100 XD and XDC have been protecting water intakes worldwide for over 20 years.

  • Environmental Water Analysis

    Now for the first time you can measure ion levels in drinking / tap water, rivers and lakes using one probe and one set of calibration solutions. We have probes specially tailored for environmental testing. Our Environmental probes measure Chloride, Ammonium and Nitrogen or we have a total nitrogen probe measuring Ammonium and Nitrogen. Each probe can be calibrated in our unique calibration solutions allowing you to calibrate all sensors simultaneously and take measurements in drinking or river water. Probes are also available in our standard four or six ion combinations and can be custom packaged upon request.

  • Oil in Water Monitoring

    Detection of hydrocarbons within both water sources and effluent intake to Waste Water Treatment Works is an increasing requirement. The UviLux Hydrocarbon fluorometer detects hydrocarbons in water at very low concentrations. This in-situ fluorometer provides a rugged sensor which can be deployed in a wide variety of configurations. The UviLux is part of the Lux range of CTG fluorometers, and can be provided with a number of options with regard to signal protocols, and has available accessories to enable in-flow monitoring as well as inclusion within portable systems for taking measurements in the field.

  • Turbidity Monitoring

    The monitoring of Turbidity is key requirement of the water industry in both water supply and water recovery systems. Within the water supply process, monitoring of turbidity allows operators to assess the efficiency of filters for particulate removal through the process. Similarly, with water recovery (Waste Water Treatment Works), the measurement of turbidity is a key parameter to track the removal of particulate through the process. CTG can provide turbidity measurements with the UniLux sensor, or provides turbidity as one of the parameters available within the 3 channel TriLux. For applications requiring turbidity measurements compliant to ISO07027:1999, CTG can offer the TurbiLux Nephelometer.

  • Drinking water solutions for the nitrate monitoring

    Problem: Nitrate, the most stable form of nitrogen in water, is found in both ground and surface water and originates from both natural and anthropogenic sources. Due to its high solubility in water, nitrate is not filtered out from groundwater like other contaminants. Removing nitrates from source water is important as elevated levels in drinking water can cause serious health effects when ingested.

  • Laser detection solutions for water-quality monitoring

    The technology of Spectral Fluorescence Signatures (SFS) is a very sensitive and selective tool to monitor many industrial processes on site and in real-time. The SFS analyzer series – SFS-Scanner and Instant Screener spectrofluorometers - are capable of detecting target substances even in complex mixtures without any pre-treatment of the samples.

  • Industrial solutions for water monitoring

    Water monitoring involves many different activitites, from ensuring the quality of surface or underground water, both for human beings and animal life, to the monitoring of a country’s water infrastructure. Wireless sensor networks are becoming increasingly popular in this area and ADVANTICSYS has already explored its use for many novel applications.

    Algae monitoring of drinking water reservoir -

    Due to green algae problems in the water reservoir of a drinking water treatment plant, the ALGcontrol was installed to continuously monitor the algae concentrations and possible toxic blue green algae blooms. During almost 4 months the ALGcontrol measured the total chlorophyll and cyano chlorophyll concentrations of the water reservoir. In order to be able to compare these results, second off-line controls were carried out using the ISO 10260 chlorophyll-a quantification (extraction into ethanol, spectrophotometric detection at 665 and 750 nm). The results of the off-line standard lab method show a good correlation with the measurements of the ALGcontrol. The good correlation can be verified as well at high as at low concentrations of total chlorophyll.

  • Water monitoring for laboratories

    Chemical purity of water is assessed for a wide variety of different chemicals depending on the type of water and applicable local legislation. 

    Chemical analysis of water can include testing for nitrogen compounds, dissolved heavy metals, and total and dissolved organic carbon.

    Common water monitoring applications include:

    • Determination of suspended solids in waterusing for example glass fiber filters.
    • Chemical analyses of for example heavy metals, dissolved organic carbons (DOC), and ions.
    • Microbiological analyses using membrane based microfiltration methods

  • 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.
