Israeli, US, German Scientists Team Up To Turn Disease-Filled Wastewater Into Drinking Water

This filtration technique differs from existing purification technologies in the way that it efficiently recycles wastewater. While popular and life-saving, desalination through reverse-osmosis companies such as Israel Desalination Enterprise (IDE Technologies) can disrupt salt water ecosystems and require immense energy input. Companies such as Mapal Green Energy, which clean wastewater using aeration (pumping oxygen into wastewater to enhance aerobic digestion), require much energy as well.

The researchers acknowledge that other filtration membrane technologies exist, but claim those use chemicals such as chlorine, which can ultimately contaminate water with byproducts and using immense energy is neither maintainable or resourceful. Therefore, the implications of this new filtration method are huge, as it can clean water sustainably, without disrupting natural ecosystems or using chemicals. For this reason, various governmental agencies such as the US Environmental Protection Agency and the German-Israeli Water Technology Cooperation Program have supported the zwitterionic polymer hydrogel research.

Recycling water will become necessary as more and more cities begin to suffer from water scarcity and because ingesting unclean water can be fatal. Consequences of contaminated water range from norovirus, the leading cause of gastroenteritis-associated mortality, to adenoviruses which can cause the common cold, sore throat, bronchitis, pneumonia, diarrhea, pink eye (conjunctivitis), and neurological disease.

Water conservation is paramount

Preserving the quality of fresh water is important for the drinking-water supply, food production and recreational water use. Humans rely on water in every facet of life, therefore its conservation and preservation is paramount. Fortunately, the new membrane has opened the flood gates to saving millions of lives by providing an innovative and sustainable system that recycles and cleans water.
