Washing Machine Uses 90% Less Water

Posted on July 31, 2009  Comments (3)

We wrote about the nearly waterless washing machine from Xeros previously, here are some additional details. The nearly waterless washing machine (which uses 90% less water) was developed by transferring known science to another application. After extensive R&D by University of Leeds scientists a nylon polymer was selected to absorb stains and dirt due to its unique property to become highly absorbent in humid conditions. Better still, it is highly resilient so can be re-used time after time without losing its strength.

The power of polymer cleaning
The nylon polymer has an inherent polarity that attracts stains. Think of how your white nylon garments can get dingy over time as dirt builds up on the surface despite constant washing. However, under humid conditions, the polymer changes and becomes absorbent. Dirt is not just attracted to the surface, it is absorbed into the center.

Such research in university settings, then transferred to products are a great source of economic growth and environmental improvement.

    Looking forward to the worldwide distribution of nearly waterless washing machines. Many people today are looking for machines that can do not consume much water and energy and this machine is definitely something to look forward to. When it comes to water efficiency, the next best you can find in the market are those machines with sud sensors. Those sensors will measure the amount of water needed to completely wash off the sud in your laundry. As soon as the nearly waterless washers hit the commercial brands,it will dominate the washer industry, i believe.

    a majority of the world must hand wash their clothes. Engineers should continue to focus on the mass of humanity that needs fairly simple solutions…
