  • Portapure

    Research into Portapure technology began the day after the earthquake that struck Haiti in January 2010. The gripping effects of the situation on the ground in Haiti, immediately after the earthquake, were striking. Witnessing the support of medical aid being donated to Haiti, we became curious about ways Haitians were utilizing water purification tablets. We wondered how Haitians without means could use water treatment tablets/chemicals on a day to day basis.

    Students at the Desai lab at the University of Wisconsin-Madison are investigating how changes in the length of lake ice seasons influence the cycling of carbon dioxide and methane. Here a LGR Ultraportable Greenhouse Gas Analyzer (UGGA), using only battery power, is applied to record chamber flux measurements of CO2 and CH4 flux over the frozen Lake Mendota in Madison, Wisconsin. A small hole is augured over the lake and the chamber is quickly placed on top to capture the emissions of greenhouse gases out of the lake. -

  • Laser-based measurements of 18O/16O stable isotope ratios (δ18O) in wine samples

    Technology

    Description: 
    Wine counterfeiting is an international, multi-billion dollar issue, with some estimates suggesting that up to 5% of wines sold at auctions or secondary markets are fraudulent. Isotope ratio mass spectrometer (IRMS) measurements of the 18O/16O stable isotope ratio (δ18O) of water-in-wine have been used for wine authentication; however, these analyses are time-consuming and costly. In this preliminary study, off-axis integrated cavity output spectroscopy (OA-ICOS) is used to quantify δ18O in wines. This laser-based method has been extensively used to study water isotopes for hydrological and medical applications. Recently, the development of a spectral contaminant identifier (SCI) has extended the application of these OA-ICOS analyzers to contaminated water samples (eg, plant, soil, and leaf waters). Here, we utilize OA-ICOS with the SCI to characterize wine samples (9%–15% ethanol), and show that the laser-based instrument provides a δ18O measurement precision of ±0.07‰ (1σ) and agrees with IRMS to within ±0.63‰ (1σ). Moreover, by training the SCI on isotopically-characterized wines, the agreement with IRMS improves to within ±0.30‰ (1σ). The utility of the instrument is demonstrated by measuring watered and mixed wines. The method presented here can be readily extended to address other food authentication applications.
  • New technology could detect radioactive threats in nuclear wastewater

    In light of the recent nuclear disaster at Fukushima's Daiichi nuclear power plant in Japan, scientists are reporting progress toward a new way to detect the radioactive materials known as uranium and plutonium found in wastewater.

  • Methods for calculating the runoff from a watershed as a part of water balance study.

    Hi this is Pandit Pandit from India and I am working in watershed development project. Recently we have undertaken a watershed of 1000 hector for development. We need to calculate the total runoff from this watershed as a part of water balance study. I am looking out for some good and reliable methods to estimate the total runoff from this area. The average rainfall of the region is 2500 mm and the soil is sandy loam to loam , with slope of 5 to 30 %.. 

    Hope to get some good suggestions, thank you.

  • OxyMem

    OxyMem is a breakthrough technology for wastewater aeration. Up to now this has been a very energy intensive process which has relied on forced, or ‘bubble aeration to deliver oxygen to the bacteria that breakdown. Pumping and treating wastewater typically accounts for up to 2.5% of all electrical power produced in a developed country. The Aeration process comprises of 60% of this energy, on average.

  • TMW Technologies

    Through the observation of oceans TMW came to understand it is possible to evaporate water at atmospheric pressure and low temperature. Once the vaporized water condensates, it becomes fresh demineralized water. This has been water’s natural recycling process for billions of years…

    TMW invested 10 years of research & development to reproduce Water’s Natural Cycle in a contained module with low maintenance and low energy needs.

    Our solutions are adaptable from small installations to industrial size plants.

  • Futuristic water-recycling shower cuts bills by over $1,000

    In space, astronauts go for years without a fresh supply of water. Floating in a capsule in outer space they wash and drink from the same continuously recycled source. So why, asked Swedish industrial designer Mehrdad Mahdjoubi, do we not do the same on Earth?

    This was the concept behind the OrbSys Shower -- a high-tech purification system that recycles water while you wash. In the eyes of Mahdjoubi, we should start doing it now, before it becomes a necessity.
