| dc.description.abstract | Introduction. In the initial coffee process exist two principal methods to remove the pulp and skin from cherries of coffee: dry method and the wet method . Wet processing consists of mechanical removal of exocarp in the presence of water using machine-pulping of the drupes , and this process requires a lot amount of water, which began after in wastewater. The pulping water contains high concentration of organic matter . This effluent is highly polluted with elevated chemical oxygen demand (COD), biochemichal oxygen demand (BOD) and suspended solids. Further influence over dissolved oxygen available and human health among people that live near to this water bodies, water pulping can affect aquatic life because of elevated acidity, strongly colored and occurrence of many toxic compounds present in coffee1,3. There are few studies about treatment of wastewater in coffee process ; and other studies employ commercial soluble coffee . The aim of this study is show the use of electrochemical process to mineralize and to reduce the color and organic matter on pulping water. | en |
