Banana peel 'good for water purification'
Thursday, Apr 28, 2011 Filed Under :Planet Talk Card News
News brought to you by Planet Talk - cheap international calls made easy.
Banana skins could soon be used by poor families in India, Pakistan, Nigeria and the Sudan to purify water.
Minced banana peel has been found to perform far better than a number of other purification materials in a new study, published in the journal Industrial & Engineering Chemistry Research.
Banana skins, along with other plant fibres such as peanut shells and coconut fibres, have proved particularly successful at removing heavy metals from water - usually an expensive process.
International calls for better water purification techniques continue to be made by international charities, to improve the life of poor populations in developing countries.
The researchers note that in addition to working better, banana skin purification apparatus could be used up to 11 times without losing its properties.
Earlier this month, FSI energy and Powell Water announced plans to collaborate on a new state of the art water treatment facility, in a bid to improve the cost effectiveness of water purification.
