This new system is affordable, easy to use and effective.
A group of researchers in Canada has developed a new way of purifying drinking water. With the news of lead contamination in California and many other places across the U.S and in rural Canada, it’s great to know that communities in need might soon benefit from having more options at their fingertips.
The technique was invented by scientists at the University of British Columbia, and it builds on previous knowledge around filtering water.
It uses a system of tanks made of fiber membranes to catch and hold contaminants with bacteria.

Yes, there are other water purification systems like it out there. This one is the first to use gravity combined with bacteria, to clean the water, though.
Usually chemicals and complex mechanical systems are needed to keep the membranes used in water filtration clean but in this case, the biofilm- a slimy thin layer of bacteria on a porous surface- catches and holds contaminants, breaking them down as the clean water filters through.
It could prove to be a lifesaver for communities. So many people need an affordable way to ensure their drinking water is up to par.
“Access to clean drinking water is a constant challenge for millions of people around the world,” says the projects lead professor, Pierre Bérubé. “Our goal is to provide a model for low-cost, effective water treatment for communities, and to help locals help themselves as they build, operate and even expand their water treatment plants.”
