    PureMadi makes ceramic water filters out of a factory in the Limpopo province, South Africa. The filters are made of local clay, sawdust and water, which are mixed and pressed into a mold. The result is a flowerpot-shaped filter, which is then fired in a kiln. The firing burns off the sawdust, leaving a ceramic with very fine pores. The filter is then painted with a thin solution of silver or copper nanoparticles that serve as an effective disinfectant for waterborne pathogens. 

  • ECOSOFTT's Water SMART Blue Communities and Users platform enables total water sustainability through end-to-end management of the water cycle. The Blue Building Standard is based on 4 overarching principals: Water Source - increase and diversify water sources; Water Use - integrate various water sources for different water use; Water Recycling - collect and recycle wastewater using appropriate technologies, and; Water Discharge - safely discharge excess water for other community needs or into the environment.

  • 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.

  • 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.
