Africa: 'Biochar' Could Help Clean Polluted Water

Africa: 'Biochar' Could Help Clean Polluted Water
A type of charcoal made from eucalyptus trees could provide the solution to South Africa's polluted water.
A University of Stellenbosch academic is developing a low-cost, low-tech water purification system with the charcoal, which will remove organic compounds from waste water in urban areas, the DST-NRF Centre of Excellence in Food Security said on Monday.
The charcoal, called biochar, could remove organic, some inorganic, and microbiological contaminants from water.
Professor Gunnar Sigge and collaborators at the Universities of Venda and Pretoria developed the purification system.
