    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.

    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.

    Surface water monitoring

    The EU Water Framework Directive (2000/60/EC WFD) is probably the most significant international legislative instrument in the water field. Water management policy as set out in the WFD is focused on surface water as it flows through river basins to the sea. An integrated approach has been introduced for matters concerning water quality and water quantity and the Directive establishes a framework for water management based on river basin districts. Linked to the WFD objectives, a series of milestones has to be complied with, including monitoring programmes.

    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.

  • 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.

    Water Testing for Environmental Applications

    Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality. Control of water pollution was once concerned mainly with treating wastewater before it was discharged from a manufacturing facility into the nation`s waterways. Today, in many cases, there are restrictions on wastewater that is discharged to city sewer systems or to other publicly owned treatment facilities. Many jurisdictions even restrict or regulate the runoff of stormwater — affecting not only industrial and commercial land, but also residential properties as well.

    Water monitoring technology for surface water

    Measuring water quantity and quality in surface water (open channels, rivers, reservoirs, lakes, and estuaries) is one of the foundations of hydrological monitoring and has been a focus of OTT Hydromet since its first  water current meters were designed in 1875.

  • Monitoring Raw Water Intake

    The Situation: Hydrocarbons in water intake used for municipal drinking water and desalination systems are commonly limited to 1 part per million. Problem: Naturally occurring organics in raw water are typically treated with chemicals. Total Organic Carbon (TOC) analyzers in the water treatment system can alert technicians when some type of organic material is present but cannot differentiate between natural organics, such as algae or leaves and hydrocarbons. Solution: A fluorescence monitor can be configured for sensitivity to hydrocarbons, with no significant response to other organics. The TD-4100XDC has the highest sensitivity to hydrocarbons in raw water, has a low cost of ownership, and can be modified with Teflon, Monel, and other corrosion resistant materials for sea water environments.

  • 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.

  • 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.

  • 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

  • Continuous Instream Monitoring

    Turbidity in natural waters is recognized as an important indicator of its environmental health, and because it's a good surrogate for suspended sediment, monitoring turbidity has always been the "holy grail" for hydrologists. But because of earlier technology, "turbidity" has traditionally been a "bad word". The DTS-12 turbidity sensor is the first sensor to make turbidity monitoring practical, and no longer difficult, inaccurate, expensive, or labor-intensive. Turbidity is the cloudiness or murkiness of water caused by suspended organic or inorganic materials. Turbidity in natural waters is recognized as an important indicator of its environmental health.

  • Wireless multiple parameter monitoring

    Monitoring multiple sensing points including fill level, pH, conductivity, and flow—often from varied locations in a large water treatment plant—can be a challenge. With four analogue inputs, a single SureCross Node can easily centralize and transmit critical monitoring information from multiple Sensors or controllers. Banner’s unique power management capability enables a single Node equipped with a FlexPower™ optimized QT50U or T30UX ultrasonic analogue sensor (level detection) to operate for years on a single DX81 battery power supply.

    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.
