    Monitoring drinking water quality

    Drinking water supply and distribution systems around the world (a critical and interdependent component of a nation’s infrastructure) are vulnerable to both intentional and accidental contamination. Unusual water quality may serve as a warning of potential contamination. The available physico-chemical sensors utilize general water quality parameters, such as free chlorine, oxidation reduction potential (ORP), total organic carbon (TOC), turbidity, pH, dissolved oxygen, chloride, ammonia, nitrate to detect the contamination. Generally, one or more of these water quality parameters will change due to the injection of a contaminant. However, no single chemical sensor responds to all possible contaminants nor can they give any indication of the potential toxicity of complex mixtures.

    Fast Water, Rivers & Lakes

    Oil spill response operations are notably difficult in rivers with strong current. In addition, when considering response times for river spills in relation to the mobilisation time required for conventional land- or vessel-based boom systems, a timely response is often a logistic impossibility especially in the more remote regions. Therefore, equipment must be readily at hand near the sites of operation and pre-rigged lines, cables and mooring areas are a must. Selection of a good location to deploy the oil containment system is dependent upon prior planning and understanding of the currents. Drift studies, river run off histories, tidal current tables and charts, plus computer modeling are all useful tools to understand the flow patterns and to develop recovery strategies. Reading the currents and flow patterns require practice and understanding of the hydrodynamics involved.

    Software solutions for stormwater and floodplain management sector

    It is the job of Stormwater and Floodplain Manager to plan, develop and manage our resources that provide a response to the hydrologic cycle and our part in it. Water evaporates, falls from the skies onto urban, rural and forested lands, and runs off into streams, rivers and lakes, as well as onto roofs, roads and urban landscapes and is utilised by those who live there. You design the physical infrastructure necessary to meet the needs of society and to preserve the natural environment, and model its ability to withstand the extremes of the hydrologic cycle.

    Core Analysis for unconventional reservoirs

    Low field Nuclear Magnetic Resonance (NMR) is routinely used in core analysis laboratories to examine the T2 relaxation time distribution of fluids in core plugs. These distributions can be interpreted to give information on: pore size distributions; permeability; total and effective porosity; free fluid index and bound water volumes. The partnership between Oxford Instruments and Green Imaging Technologies allows us to integrate hardware and software to enable any core analysis laboratory to generate these petrophysical results without the need for in-depth knowledge of NMR.

  • GIS software for water resource industry

    GIS is a powerful tool for developing solutions for water resources such as assessing water quality and managing water resources on a local or regional scale. Hydrologists use GIS technology to integrate various data and applications into one, manageable system. The suite of tools contained in Arc Hydro facilitate the creation, manipulation, and display of hydro features and objects within the ArcGIS environment.

  • Waste water respirometry solutions for process optimisation

    Respiration rate of activated sludge has been recognised as a key controlling element in the modelling of process control, by the International Water Association Task Group. Actual respiration rate of the sludge in the aeration tanks, as well as the endogenous and maximum respiration rates are variables that indicate the rate of BOD removal and aeration requirements. The maximum respiration rate is also closely linked to the Critical Oxygen Concentration point, that is, the point at which diffusion over the bacterial cell walls ceases and therefore biodegradation is significantly compromised.

  • 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.

  • Data analysis and visualization tools for groundwater modeling

    Groundwater and Solute Transport modeling is a sub discipline of environmental sciences with unique needs. Modeling has long utilized 3D simulations, but the ability to visualize the results has lagged far behind the simulation technology. EVS-PRO and MVS have long offered professional level presentation tools worthy of the current state-of-the-art in modeling, and EnterVol now opens that door to GIS professionals around the world. Visualization of groundwater and solute transport modeling results can be performed from third party modeling systems such as USGS MODFLOW, MT3D, GMS©, Groundwater Vistas and Visual MODFLOW© using C Tech’s tools to convert these modeling outputs into EFF format. In conjunction with Lawrence Livermore National Laboratory and IT Group, C Tech performed the visualization and animation of the output from a Groundwater Vistas MODFLOW and MT3D99 simulation of a large industrial complex in the central valley area of California.  This site exhibits highly channelized flow which is evidenced by the flow paths. Note that flow in the lower aquifer crosses underneath the upper channels at about 30 degrees!

  • Water Contamination Detection

    Security of water assets is becoming an increasingly major issue that demands immediate and robust alarms for potential contamination. In addition to this, natural growth of algae is a common problem for water asset managers, the results of which can increase maintenance costs of water processing plants as well as directly effecting water taste. The CTG FastGuard fast repetition rate fluorometer analyses information on the physiological state of the algae it monitors within an in-line flow system. A number of key parameters are monitored and analysed by the on-board embedded software, which instantly initiates both an audible and visual alarm on detection of a contaminant within the water system. The FastGuard is a robust low maintenance system which avoids false positives often provided by other contamination detection systems.

  • Vacuum excavation solutions for micro-tunneling / foundation stabilization sector

    Vac‐Tron vacuum excavation equipment can be used for the application of Micro‐Tunneling and/or Foundation Stabilization. Microtunneling is used to construct small tunnels. This process enables access to plumbing, electrical wiring, termite repair, flooding, crawl space and historical restoration without compromising the integrity of the foundation. By using the “soft‐dig” technique under the foundation or slab, there is no risk of damaging any previous utilities or structural damage to the building. The debris removed will only have to be handled one time. This process would be best served with the Vac‐Tron AIR855 model to accommodate the volume of debris, as well as having the flexibility of back‐filling with the dirt that was removed after the process has been completed.
