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.

Data analysis and visualization tools for ocean and lake sciences

Oceanic and lake sciences challenge the abilities of traditional software tools. Virtually everything of interest lies beneath the surface. This is a 3D world with complex issues that affect the life in these water bodies and all life on Earth. EVS, MVS, and EnterVol’s modular toolkits provide the technology to address a myriad of surface and subsurface issues.

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.

Drinking water treatment

Drinking water can be produced from any natural sources like groundwater, lakes and rivers (surface waters) or seawater. Drinking water standards are set by the World Health organisation or by the European Union. Drinking water must be free of suspended solids, microorganisms and toxic chemicals. Mineral concentration recommendation vary from country to country but most of the minerals have a maximum concentration recommended to ensure safe, equilibrated and pleasant water to drink.

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.

Groundwater Monitoring for Water Resource Management

One of the greatest problems facing the planet is the management, conservation and equitable distribution of fresh water supplies. The fresh water sources may be lakes, rivers or ground water aquifers, most of which are now under stress.

Water Treatment Solutions for Turbidity Removal

Turbidity is a measure of the loss of light transmittance through a liquid due to suspended particles. The more particles in the water, the murkier it looks or the higher the turbidity. This is a measure of the quality of the water. It is measured in units called Nephelometric Turbidity Units (NTU). Turbidity can be caused by run off after a heavy rain as erosion washes soil into a river or lake. It is often increased in the spring and fall when the water temperature at different levels in a lake change causing a turnover of those levels, bringing sediment, plants, and algae to the top.

Environmental Water Analysis

Now for the first time you can measure ion levels in drinking / tap water, rivers and lakes using one probe and one set of calibration solutions. We have probes specially tailored for environmental testing. Our Environmental probes measure Chloride, Ammonium and Nitrogen or we have a total nitrogen probe measuring Ammonium and Nitrogen. Each probe can be calibrated in our unique calibration solutions allowing you to calibrate all sensors simultaneously and take measurements in drinking or river water. Probes are also available in our standard four or six ion combinations and can be custom packaged upon request.

Dye Tracing

Monitoring the dilution and movement of a tracer introduced into the water column provides an excellent means of determining the path that may be followed by a discharge and the rate at which dilution is likely to take place. Fluorescent dyes such as Rhodamine, Fluorescein or Agma are the most frequently used tracers for such investigations. Chelsea Technologies has been providing dye tracing systems for over 30 years. Typical applications include sub-sea pipeline leak detection, pollution studies, natural water flow analysis (rivers, lakes, ocean currents, cave water flows, groundwater filtration etc), sewer and storm water drainage analysis. The Chelsea systems can be configured for a wide variety of tracers, are highly sensitive, robust, and deliver real-time data. They can be moored, profiled, towed or affixed to ROV / AUV platforms.

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.

Compressed air, gas and vacuum solutions for water and waste water treatment

There are many options to apply methods to avoid damaging the environment. In the case of wastewater e.g. the ventilation of the sediment tank or the pressure ventilation of biological wastewater treatment systems. The oxygen introduction is important, for deep wastewater tanks, wastewater treatment systems with standard aeration tanks or natural clarification ponds alike. If the wastewater has already entered the natural cycle, ventilating lakes and rivers prevents additional contamination. When treating drinking water, rinsing the filters with compressed air ensures that perfect water is provided and natural water reserves are not used excessively.

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.

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.
