river monitoring Applications

  • River Level Monitoring -

    SUMMARY Fielded water level measurement stations, based on GaugerGSM sensor, report real time stream levels and flow. Stations are located across a stream-rich region of the upper Galilee feeding the Jordan river in the northern part of Israel. The region is a popular tourist destination due to its biblical origins, rich flora and fauna. Field data is available over the Internet to authorized engineers, site supervisors and Government officials. remote monitoring station - close up THE NEED The water basin in the Upper Galilee maintains a delicate balance between recharges, net precipitation, domestic and irrigation consumption, and water tourism (canoeing). Local and state officials are tasked to study the tradeoffs, manage risks and take actions to keep the balance. Monitoring stations are essential for data collection. remote monitoring station - overall

    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.

  • Monitoring Sewage Flow

    Monitoring Sewage Flow is a critical tool for local governments, for water and waste-water utilities and for industrial plants. Sewage monitoring can prevent environmental disasters such as sewage overflow within populated neighborhoods or excessive waste flow into local lakes, rivers or sea. Sewage monitoring is also an important tool for short term and long term planning of the sewers infrastructure. Short term refers to just-in-time and cost effective maintenance. For example, sending the technical team to the correct manhole at the correct time to clean and eliminate obstructions. Long term planning refers to designing the correct pipe diameters and correct slopes to contain sewage from new new buildings and plants. Sewage monitoring is a tool for billing plants who produce sewage above their water intake and a tool for plants which utilize water to request lower utility bills. Solid Applied Technologies provides a complete and tested solution for Sewer Monitoring.

  • 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.

  • Sewer Meter -

    Sewer Meters monitor sewage level and flow within the sewers. Benefits gained by sewer monitoring include: (1) Detection of overflow conditions before overflow occurs thereby preventing hazardous environmental events. (2) Detection of blocked sewer pipes, allowing quick and focused maintenance thereby reducing maintenance costs. (3)Detection of over-used and under-used pipes for long term municipal planning. (4) Monitoring of sewage flow in sensitive sites such as flow to the river or sea. (5) Estimation of sewage flow for costing purposes and especially for pricing the use of public infrastructure by industrial plants. The sewer meter solution consists of two main components: (1) The fielded component includes GaugerGSM, an ultrasonic non-contact level sensor integrated with GSM cellular transmitter. The fielded component also includes accessories such as external battery pack. (2) A web-based monitoring application for presenting data from all sewer sites.

    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.

    Seawater Biotoxicity monitoring to protect the coastal waters of Italy

    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.

    Surface Water Quality Testing for the Environmental Monitoring Industry

    Aquaread stock a wide range of testing equipment designed to track a number of parameters and water quality testing measures. These can be used in many different bodies of water, including rivers, lakes, streams and seawater. The advantages of tracking water quality and testing for numerous parameters means that it is easier to notice changes which could cause damage to aquatic ecosystems. Early detection not only helps with monitoring water quality, but also helps to put mitigating measures in place. We have a wide range of parameters, although the most popular of these allow for surface water testing, pH, temperature, electrical conductivity and measuring levels of dissolved oxygen. These are standard measurements included in most standard Aquaprobes, although if you require more specific parameter testing then there are a number of additional parameters which can be added onto to the base Aquaprobe to compensate this.

    Monitoring once through cooling water

    The Situation

    Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil.  These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often use once through cooling water systems. The cooling water is taken from lakes, rivers, or the ocean and circulated once through the plant to cool processes. Large volumes of water are used to keep the return water temperature low enough to prevent adverse effects on the environment.

    Monitoring of hydroelectric dam sumps

    The Situation

    Hydroelectric dams produce electric power by harnessing the force of the water flowing through the dam. There are numerous sources for oil spillage:

    • The hydroelectric turbines are lubricated by lubrication oils.
    • The very large water control valves are normally hydraulic powered and are lubricated with various greases and oils.
    • Vehicles including fork lifts, trucks, etc., can spill oils and fuels.

    Any accidental spillage of oil or grease or intentional wash down water containing minor amounts of oils, greases, and detergents must be collected and treated before discharge to the river. These fluids along with any water leaks are collected in sumps in the dam and are regularly pumped out. In many cases, the volume of water is substantial.

  • Monitor Dredging Slurry Flow

    Thousands of dredges are operated to maintain navigation channels in our rivers, lakes and harbours and to mine sand and gravel for the construction industry. Managing and optimizing production from a dredge requires continuous monitoring of pipeline pressure, vacuum and slurry velocity. The operating conditions are extremely harsh and any sensing components in contact with the abrasive slurry can be damaged. But dredge operators need accurate real-time flow information to properly manage production so equipment manufacturers have been seeking innovative monitoring solutions...
