Study of Coffee Husk (coffea Arabica L.) Activated Carbon in the Treatment of Aquifer Water: Adsorption of Turbidity, Colour and Metals (iron-manganese)

Abstract

The aim of this study was to determine the effect of activated carbon obtained from coffee husk (Coffea arabica L.) on the adsorption of turbidity, colour and metals (iron-manganese) present in aquifer waters, in order to contribute to the treatment of confined waters susceptible to contamination, in a natural way due to the geographical conditions of the soil. The variables evaluated were: activated carbon from coffee husk and adsorption of turbidity, colour and metals (iron-manganese). The adsorption capacity of the activated carbon of an agro-industrial waste was determined by applying different concentrations of the substance obtained experimentally on the water of the aquifer to be treated. The data were statistically analysed at two points in time; by means of the analysis of variance it was possible to show that the variations in the weight of the carbon, speed, volume and mixing time did not significantly influence the removal of pollutants; the removal percentage was determined, where the results obtained demonstrated the adsorbent effect of the activated carbon on turbidity, colour and metals (iron-manganese).
