REMOVAL OF PHOSPHATE IONS IN WASTEWATER BY COUPLING CHEMICAL TREATMENT- ACTIVATED CARBON TREATMENT: CASE OF AN URBAN WASTEWATER OF THE CITY OF YAMOUSSOUKRO (COTE D?IVOIRE).
Journal Title: International Journal of Advanced Research (IJAR) - Year 2018, Vol 6, Issue 12
Abstract
This study focuses on the removal of phosphate ions from the method of co-precipitation in wastewaters of the city of Yamoussoukro. She contributes to various methods of struggle against the \'\' cancer \'\' of surface waters which is eutrophication. The chemical treatment of wastewater allowed in an average reduction phosphate ion rate of 89.00 %. On the other hand, the elimination of phosphate ions with activated carbon (fresh coconut fiber) brought on average a small increase, of the order of 2.00 %. So a reduction rate in total phosphate ions of about 91.00 % of the chemical treatment-activated carbon treatment coupling of this urban wastewater. The coupling activated carbon treatment with the method of co-precipitation of phosphate ions does not seem to give convincing results. We can assume that the precipitates contained apatite because all final pH are higher than 9.
