water current Applications

  • Electrodeionization

    The Fractional Electrodeionization (FEDI) process is an advancement of conventional EDI. The patented dual voltage process allows for a higher flexibility and tolerance to inlet water conditions, thus lowering the risk of scaling, and improving the plant& design economics and reliability. By incorporating a two-stage separation process with different voltages the FEDI process is able to: Achieve a higher hardness tolerance by having distinctly different concentrate chambers with separate reject streams and thus reducing the potential of hardness scaling. Optimize power consumption by using higher electrical current only where required. Ensure the best water quality, continuously consistently by removing a major part of the deionization load in the hardness removal zone, while residual ionic impurities are effectively removed in the silica removal zone;, which stays in a polishing mode.

  • 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.

    Cooling & Drinkingwater: ATP monitoring of biomass growth in waters

    Monitoring Biomass in (Cooling Tower) Waters through ATP monitoring

    The TOXcontrol can be used for ATP monitoring. Currently our company is doing research for further developments for this application on the TOXcontrol.

    Monitoring the microbial population of cooling towers is necessary in order to maintain the proper operation of the system. Conventional methods for monitoring microbial populations work by culturing microorganisms, a time-consuming procedure that requires days or even weeks of incubation before the results are known. Biofouling can be well-advanced before treatment begins. In addition, it is believed that this technique does not detect the full range of microbial life present in cooling systems.

  • Odor control solutions for wastewater industry

    Municipal wastewater treatment plants (wwtp) provide an essential community service that is vital for the protection of public health and the environment in which we live. Without affordable wastewater services, the quality of life within a community or municipality can be drastically diminished. Most cities, towns and communities in the US and Cananda provide wastewater treatment services, unfortunately these services and plants come with many undesirable off gasses and odors. There are a number of challenges that currently face the wastewater treatment industry including, global urban population growth, more stringent discharge regulations for industries, and demand for water conservation through wastewater reuse.

  • Ozone generators for laundry application

    In recent years ozone laundry technology has proven itself to be an effective tool in helping to reduce water usage and energy consumption while also reducing wash and dry times, ensuring the absence of microorganisms, and improving the quality and useful life of laundered products. There are economic advantages to an ozone system as well as microbiological and environmental benefits. Currently in the United States there are over 2,000 ozone laundry systems in place and as many as 3,000 more in the United Kingdom alone.

  • Water treatment for food processing

    Most food processing facilities currently use a combination of different chemicals for all surface and machine disinfection. They periodically rotate the use of different sanitizers to prevent the harmful microorganisms from building a resistance to their killing properties. Unfortunately facilities are still experiencing pathogen outbreaks. Chlorine dioxide’s unique killing ability does not allow for the build up of resistance or mutation, and therefore eliminates the need for all of the other chemicals. Chlorine dioxide is effective for use in controlling microbiological growth in flume waters and other food processing water systems such as chill water systems and hydrocoolers.

    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.

  • Erosion & sediment control solutions for costal/beach region

    Coastal erosion is the wearing away of land or the removal of beach or dune sediments by wave action, tidal currents, wave currents, or drainage. Removing sand and other materials from beaches and dunes due to tidal storm surges and construction purposes causes massive beach erosion damages and land loss of seashores, thus destroying the natural heritage of the coast and reducing the vibrancy of the tourism industry. Uprooting vegetation from coastal areas destabilises beaches and clearing sites inland results in increased soil and dirt particles being washed offshore and smothering coral reef systems.
