surface water monitoring Applications

  • 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.

    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 surface water for wastewater treatment industry

    Pollution Risk: Surface water encompasses storm water derived from hard standing areas, river water and reservoirs. All types of surface water are at risk from ingress of pollution and therefore need to be monitored. On-line continuous monitoring can identify and alarm pollution so corrective action can be taken

    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.

    Drinking water solutions for the source water monitoring/ protection

    Problem: A challenging aspect of drinking water treatment is often predicting or monitoring the changes that occur with incoming water quality. Seasonality, weather events, agricultural practices or upstream discharges can influence the quality of both ground and surface water over time. With multiple variables impacting source waters, monitoring historical trends may not be sufficient to predict raw water changes or detect uncharacteristic events.

  • Continuous Monitoring of Nitrates and Other Water Quality Parameters

    Nitrate is one of the most important parameters in assessing surface and ground water quality. Nitrates are naturally present in surface and ground waters in low concentrations, but are harmful to humans and livestock and cause aquatic ecosystem degradation in high concentrations. Nitrates enter the environment as human-induced pollution from a variety of sources, but the largest source is from agricultural fertilizer runoff . Other sources include wastewater treatment discharge, septic systems, and from pet waste. Nitrate is highly soluble in water and therefore readily leaches into water sources, whereas other human associated pollutants, such as phosphates and ammonia, are not transported as easily. This ability to be quickly transported into ground and natural waters such as drinking water wells, aquifers, reservoirs, lakes, and streams, coupled with its health and environmental implications make nitrate pollution and monitoring of major concern.

    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.

    Reduce biofilm formation

    In many industrial or professional applications where water is being stored, biofilm may grow. The growth of biofilm can damage the installations and reduce efficiency of the circuit. A biofilm can grow certain substrates which can be found in water. When temperatures are high, for example in cooling towers, a matrix of different micro- organisms such as bacteria, fungi, algae can grow very rapidly causing the formation of a biofilm on certain surfaces submerge in water. During the formation of this biofilm, certain micro organisms starts producing extra cellular polymeric substances (EPS) which reinforce the biofilm structure.

  • 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.

  • Groundwater Monitoring for Construction Sites

    All construction affects groundwater and a water management plan will be required. From deforestation to urbanisation, from holes to heaps and dams to drains, they all have an affect on the groundwater. Deforestation causes an increase in the rate of run off of rainwater resulting in lower percolation of precipitation into the soil and a consequent increase in soil erosion leading to slope instability, hence land and mud slides. The increased rate of run off can cause small streams and large rivers to rise and flood in a shorter time, but also to dry up sooner. These conditions cause great difficulties for subsistence farmers in developing countries. Urbanisation also causes faster run off because of the non permeable surfaces such as roads, roofs and car parks. This also creates drainage problems that can lead to contamination and erosion of natural water courses.

  • Monitoring of VOCs in Porewater

    Monitoring VOCs in porewater in the unsaturated zone is now possible.

    Sorbisense regularly offers new options for using the patented Sorbicell, which is used to monitor surface water, wastewater and groundwater.

    The latest is almost as “ground-breaking” as the SorbiCell itself. Until now it has been difficult, if not impossible, to directly monitor for volatile substances in pore water in the unsaturated zone. But the environmental consultancy firm Ejlskov A/S in Aarhus combined the use of Sorbisense sampling equipment with the proven technology of soil water samplers. With this combination, a practical new method is made available, which allows for monitoring the presence of porewater-dissolved VOCs above the groundwater table. This provides a significantly improved basis to define and determine the leaching risk to the groundwater, and thus allows for better and more cost-efficient decisions to prevent the pollution in reaching the groundwater.

    A simple construction with multiple options

    The application uses SorbiCell VOC combined with suction cells, soil water samplers. When installed correctly, and applied with the correct procedures, the suctions cells extract capillary bound water from the soil matrix. The system demands no other resource than a container that is put under vacuum. The vacuum in the container then ensures a flow through of the Sorbicell over a period of time, fx. 2-3 weeks. The method is highly suitable for monitoring a site over longer periods of time.

    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.
