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.
