  1. Development of a Coupled Solar-Biological System for the Disinfection and Elimination of Organic Contaminants in Drinking and WasteWaters in Rural Areas of Colombia(BIOSOLAR-DETOX)

  2. Dr. Cesar Pulgarin Dr. Janeth Sanabria Dr. Norberto Benitez Dr. Miguel Peña Responsibles

  3. Cali Project Location in Colombia

  4. Scientific targets • Drinking Water Treatment by Coupling of Filtration and Helio Photocatalytic Processes • Domestic Wastewater Reusing in Agricultural Activities after Combined Biological Helio-Photocatalytic Treatment • Agroindustrial wastewater treatment by a coupled Helio-photocatalytical-biological system

  5. Schematic Representation of the Water Uses in the Colombian Water Cycle

  6. Natural Receptors highly Contaminated Non Treated Domestic Waste-Waters

  7. Chlorination is a widely used technique for the disinfection of water. Its bacterial inactivation effect has been proven but a great concern is that chemical risks could be enhanced due to by-products formed during the chlorination process. Water disinfection Therefore, the necessity to find low cost, environmental friendly and sustainable alternative, or complement, to chlorination.

  8. Disinfectants and disinfection-by products (DBPs)apparition of chemical riskto human THMs: CHCl3, CHCl2Br, CHClBr2, CHBr3 haloacetates, haloacetonitriles, haloacetaldehydes, haloketones, halofuranones, chloropicrin, chlorate aldehydes, carboxylic acids • Chlorine • chlorine dioxide • chloramine • Ozone • hydrogen peroxide Halogenated compounds, chlorite, chlorate Cyanogen, chloride and others generally thought to be the same DBPs as chlorine, but lower concentration Bromate, hydrogen peroxide bromomethanes, bromoacetates, bromoaldehydes, bromoketones, iodinated Analogs, aldehydes, carboxylic acids Carboxylic acids UV Not DBPs

  9. TiO2- semiconductor photocatalytic process
