'Miracle tree' that purifies water

According to the American Chemistry Society, scientists have discovered a new method that can inexpensively and effectively purify water. Popularly known as 'the miracle tree,' the moringa oleifera has long been an important staple for nutrition, medicine and hundreds of other uses throughout rural areas. Though the miracle tree’s water purifying properties have been found in past research, older methods proved too costly. Now a new method has been discovered that is less expensive; purification is achieved by adding positively charged Moringa seed-derived proteins to negatively charged sand that binds to and kills microbes and other bacteria in water. This discovery could lead to a sustained clean water source for developing countries that lack access to clean water.
