Water purification

Technology Type Group:
Definition:
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water.

Water purification

  • Cost-effective water purification

    Type: 
    Product
    Technology:

    AQUATAL has been providing the world with optimal water purification and filtration systems that produce healthier cleaner and tastier water at a fraction of the cost of mineral water. The group has been active in the development production marketing and exporting of water treatment technologies in a number of areas: water dispensers water purification systems anti scale (calcium build-up) water from the air retail products. AQUATAL’S vision is to continue providing original efficient and effective products as well as consistently excel in pre and post sale services.

  • Integrated Ultrafiltration and Reverse Osmosis Process and System

    Type: 
    Product
    Technology:

    Technology Description: Professor Cohen and colleagues have developed a compact and self-adaptive integrated water ultrafiltration and reverse osmosis (UF/RO) process and system. Designed to produce up to 18000 gallons of drinking quality water per day with no intermediate tanks between UF and RO or for UF backwash the system can be further expanded for even larger capacity. In addition the system is remotely monitored and is self-adaptive making use of advanced model-based control. Applications: Water treatment

  • Electrochemical Method for the Removal of Heavy Metal Ions from Water Based on Superparamagnetic Nanoparticles

    Type: 
    Product
    Technology:

    Background: This invention relates with removing heavy metal contaminants from water. Cadmium and lead for instance are often present in detectable quantities in drinking water from pesticides and paints respectively which leach into the water system. Technology Description: The technique utilizes superparamagnetic nanoparticles (typically iron-based which are not toxic) functionalized with covalently-bonded surfactants bearing chemical groups that are capable of binding the heavy metal ions reversibly.

  • Method to Prepare IR-activated Photocatalyst Systems and its Applications

    Type: 
    Product

    Photocatalysis offer a variety of applications such as: a non-energy intensive approach for chemical waste remediation self-cleaning applications sterile coatings and processing water purification air purification energy generation and photocatalytic cancer treatment. The current photocatalyst technologies rely on UV radiation to activate the photocatalyst which has its limitations besides being a hazardous form of radiation. Current limitations preventing widespread industrial use of UV activated photocatalytic systems are the low photocatalytic efficiency and scale-up problems.

  • Hydrogen Peroxide Sensing Electrode

    Type: 
    Product
    Technology:

    Background: Hydrogen peroxide (H2O2) is used for environmental and industrial applications—such as drinking water Purification when used as a disinfectant. H2O2 use for environmental applications is not only economical but it also does not produce harmful by-products. Control over the level of H2O2 in a fluid is essential in wastewater treatment. Technology Description: This novel detection probe provides a method for continuous monitoring of H2O2 levels in environmental or industrial fluids.

  • Solvatten

    Type: 
    Product
    Objective:

    Solvatten is a combined portable water treatment and water heater system that has been designed for off-grid households use in the developing world. It is an easy, innovative solution that gives access to clean, hot water to impoverished people throughout the world. Millions of primarily women and children need to walk dozens of miles every day to fetch water. Reducing the daily use of firewood and having a water source closer to home makes their lives so much easier.

  • Järven Ecotech

    Type: 
    Product
    Objective:
    Technology:

    Järven Ecotech designs and installs complete treatment plants for purifying and collecting surface/storm water, leachate, industrial water and sewerage water. For example, Järven Ecotech’s totally unique floating walls/baffles can replace conventional surface/storm water purification solutions on the market, such as dug/excavated surface water basins, sedimentation tanks and filtering solutions.

  • Laduvikens Waterparc

    Type: 
    Product
    Objective:
    Technology:

    At Laduviken, 5 million Swedish kronor is invested in a water park, which will reduce the amount of pollutants entering the lake through storm water. The aim is, among other things, to reduce phosphorus by 25%.

  • Myrsöns wetlands - cleaning verdure

    Type: 
    Product
    Objective:
    Technology:

    An artificial wetland was built in the spring of 2006 next to the lake Myrsjön in Nacka. The aim is to use nature’s own mechanisms to clean the polluted storm water from an industrial area, before it runs into the lake Myrsjön.

  • Ringsjö Potable Water Plant, Stehag

    Type: 
    Product
    Objective:
    Technology:

    The Ringsjö plant draws its water from Lake Bolmen through a tunnel that was opened in 1987. The plant regularly delivers 1,600 litres of water per second to 16 different municipalities in the Skåne Region with a maximum capacity of 2,400. The plant itself was opened in 1963 and completely rebuilt between 1994 and 1997, when a new lamella sedimentation basin was added. The process combines lamella sedimentation with a sequence of filters before the final step of pH adjustment with lime water takes place.
