  • Composite for Humidity Control Porous Board using Water Treatment Sludge and Manufacturing Method of the Humidity Control Porous Board

    Type: 
    Product
    Technology:

    The present invention relates to a composition for a porous humidity control board comprising: water purification sludge powder obtained by heat-treating at the temperature of 500 to 700̊C water purification sludge generated in the treatment process which is performed in a water purification facility that produces tap water; 70 to 130 parts by weight of waste glass powder with respect to 100 parts by weight of the water purification sludge powder; 10 to 40 parts by weight of one or more substances selected from silica powder and zeolite powder with respect to 100 parts by weight of the wate

  • Water Purification Membranes Bearing Antimicrobial Polymers

    Type: 
    Product
    Technology:

    Background: Thin-film composite (TFC) membranes for reverse osmosis and nanofiltration are widely used in the production of drinking water desalination and wastewater treatment. A major problem with these membrane-based technologies is the accumulation of microorganisms which leads to biofilm growth and biofouling. Cleaning methods for TFC membranes have proven ineffectual or problematic. For example chlorine generates harmful byproducts and is unsuitable for most water treatment applications.

  • A Simple Approach to Hierarchical Ceramic Ultrafiltration Membranes

    Type: 
    Product
    Technology:

    Ceramic membranes are receiving increasing attention as ultrafiltration materials in pollution prevention resource recovery and waste treatment due to their high strength and tolerance to extreme conditions involving solvent pH oxidation and temperature. Conventional sol-gel routes to alumina-based membranes and filters suffer from poor control of resulting pore sizes and distribution. Because membrane selectivity is primarily dependent on these factors this drawback affects the performance of the materials in ultrafiltration applications that often demand pore sizes down to 2mn.

  • Superabsorbent Sustainable Aerogels

    Type: 
    Product
    Technology:

    Background: Aerogels are the world’s lightest solid materials made by removing liquid from gels. Such materials may contain up to 99 percent air and have special properties like high porosity and absorption. One promising application for aerogels is environmental cleanup. They could be used to purify water contaminated with crude oil fuel organic solvents and metals like lead and mercury. Technology Description: UW–Madison researchers have developed organic aerogels with excellent absorbent properties.

  • Novel Phase Transfer Method for Functional Water-Soluble Nanocrystals

    Type: 
    Product
    Technology:

    Background: Nanoparticles synthesized in organic solvents have a wide variety of potential applications requiring aqueous solutions. There are no current phase-transfer methods currently capable of achieving highly uniform distribution of these nanoparticles in water. Technology Description: The present invention is a method of transferring hydrophobic nanoparticles into water. A small amount of excess oleic acid below critical micelle concentration is added to the organic solution containing the nanoparticles.

  • Method and System for High Recovery Water Desalting

    Type: 
    Product
    Technology:

    Technology Description: Professor Cohen and colleagues have developed a method and system to continuously sustainably and inexpensively desalinate high salinity water of high mineral scaling propensity. The system is able to process waters as contaminated as industrial agricultural and mining wastewaters with recovery levels reach in excess of 90-95%.

  • 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.

  • 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.
