In 2007, per capita water availability in Brazil reached 43,027 m3 per year, above the world average of 8,209m3 per capita in the same year. However the distribution is very uneven with major Coastal cities such as Riode Janeiro, São Paulo and Recife suffer effects of upstream residential and industrial sewage contaminatingfeeder rivers, lakes, and the ocean. In 2000, only 35% of collected wastewater received any treatment. Thisproject is the development and roll-out of a ost effective, low energy UK innovative technology solution towastewater treatment and water reuse to an established Brazilian Wastewater treatment company. Thetechnology to be developed is to add UV assistance to a catalytic mesh oxidation process in a novel reactordesign to degrade recalcitrant pollutants, e.g. surfactants, petrochemicals and pesticides. Environmentallyfriendly hydrogen peroxide is used at room temperature in the process to oxidise pollutants to harmlessbiodegradeable organic acids or carbon dioxide and water. Treatment duration will be optimised to meet therequirements of the specific water reuse.
