This research was aimed at evaluating the adsorption process with activated carbón for the treatment of landfill leachate, based on the reduction of organic matter. It was considered to develop the adsorption process between leachate from the Cajamarca landfill and activated carbon in a jar test equipment. It began with the characterization of the influent based on total COD and BI (BOD5/COD) mainly; subsequently, the selection of the activated carbon to be used, the evaluation of the amount of carbon and the contact time, and the estimation of the adsorption isotherm, based on the removal of total COD, were developed. The research ran from June to August 2019. The leachates evaluated are classified as intermediates with low biodegradability, which require physicochemical processes for the purification of organic matter. On the other hand, the activated carbon CARBOSORB PAC 18 presented good affinity with the total COD present in the leachates and better adsorptive capacity compared to the others evaluated carbons. In addition, it was evidenced that, with a higher quantity of CARBOSORB PAC 18, better total COD removals are obtained by adsorption, stabilizing the maximum removal level from 20 g/L; similarly, the longer the contact time, the better the removals are achieved, which stabilize after 60 minutes; with this amount of activated carbon (AC) and contact time (CT), the maximum removal of total COD obtained was 75%. The Freundlich isotherm was the one that governed the adsorption process, with which the following theoretical removals of total COD were estimated: 60% with 4 g/L of AC, 65% with 7.5 g/L, 70% with 15 g/L and 72% with 20 g/L; Furthermore, reaching 60% removal would mean a monthly investment of S/. 1.15 per family for the supply of activated carbon. From the results obtained, it is argued that the adsorption process studied allows reducing the organic matter present in the leachate from the Cajamarca landfill. However, despite the high efficiency presented, it still requires an additional process to satisfy the current legal framework.
