Surface Water Monitoring Applications

  • Data analysis and visualization tools for surface water modelling

    Volumetric modeling of surface water bodies to include mapping of properties data into the volume requires the capabilities only found in EnterVol. When trying to assess the health of a lake, river or stream, volumetric data is essential. Once you apply the capabilities of EnterVol to this task, you’ll discover trends in your data that were previously hidden or suppressed by the limitations of 2D techniques.

  • Water quality monitoring for environmental industry

    Maintaining the quality of natural waters provides numerous economic benefits by preventing severe deterioration of water resources that would require expensive treatment operations to protect public health and the environment. For instance, monitoring nitrates in surface waters can possibly prevent algal blooms from happening by facilitating the necessary steps to stop pollution sources from discharging nitrogen nutrients into the water system.

  • Electrical Based Tomography Systems for Interface Detection

    Level detection is a very widespread measurement requirement. Whilst there are many techniques for detecting liquid surfaces, it is much more challenging to identify the interface between liquids and other systems.

    Gas monitoring instruments and systems for greenhouse gas emissions from soil

    Measurement of greenhouse gases released from soil and water surface forms an important part of climate change study. Microbial activity in the soil or for instance the melting of permafrost releases greenhouse gases such as Methane and nitrous oxide N2O into the atmosphere. Measurement of the concentration for these gases inside an open-bottom soil chamber placed on the soil over time tells the emission rate (flux) per chamber footprint area.

    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.

    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.

  • Microbial testing for chemical products industry

    On-the-spot measurement for microbial risk management! Microbial growth in industrial chemicals can present a major problem.· If left unchecked, microbial contamination in raw materials and intermediate products can compromise manufacturing process performance and equipment integrity.· These same sources can also impact final product quality, which if not properly maintained can spoil products while sitting on the shelf.· The best solution is early, accurate detection and proactive treatment.

  • Continuous Monitoring of Surface Water

    The Sorbisense method is especially suitable for measurements in dynamic environments. For example, in rivers, streams and lakes.

    The method is innovative and allows you to implement continuous and cost effective measurements in both urban and in rural areas. For example, measuring the leaching of nutrients from the cultivation of wetlands and measuring water quality in rainwater and sewage.

  • Example of GPR application on fresh water reservoir

    GPR exploration of fresh water reservoirs allows user to examine in details the bottom. The important feature of GPR use that is to be mentioned - it can examine the structure of the bottom. I.e. there is possible to find underwater items located inside the bottom stratum. Also GPR can provide an information about the thickness of bottom silt or bottom ground, and its volume structure. The same exploration is very problematic if made by other means. In the summer 2012 VIY3-300 GPR was examined as sub-bottom profiler. The tests were made in Kyiv, Ukraine. GPR was placed in a plastic tub and moved across the surface of the fresh water lake. The survey window number of 166 ns corresponds to the depth of 2.7 meters. The signal reflected from the bottom is clearly visible on the profile. Compensation of the signal attenuation along increasing depth reached 60 dB. That indicates the water condition in an urban area.

    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 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.
