“…Figure 5 shows the experimental data for the adsorption equilibrium of the binary solution of CA and CGA on GAC at 25°C and pH set to 3. This pH value was selected considering that the residual water from the coffee production process has similar pH value (Haddis and Devi 2008;Selvamurugan et al 2010;Alemayehu et al 2020). The experimental data for the binary system was interpreted by the extended multicomponent Langmuir (EML) model, which is described in Equation 13.…”

“…In addition, coffee processing wastewater has a COD of 3,100-14,343 mg per liter and BOD of 5,000-35,000 mg per liter, which will cause water pollution and disrupt the water ecosystem if it is dumped directly into the river. Furthermore, coffee processing wastewater possesses all the qualities of polluted water that could negatively affect water bodies, soil, human health, and plants unless an appropriate wastewater treatment system is implemented [9].…”

“…Según Estadísticas de Comercio Exterior Costa Rica (2017), esta cuenta con un valor aproximado de US$ 228 millones correspondientes a 1.451.100 fanegas (saco de 46 kg) exportadas [1]. El proceso de producción es altamente contaminante, ya que solo el 6% del peso total del grano se emplea para preparar la bebida y el resto son desechos sólidos como cascarilla, pulpa, mucílago y pergamino; y líquidos conocidos en la industria cafetalera como aguamiel [2,3]. El agua residual del procesamiento del café está compuesta mayoritariamente por agua, fibra y pectinas; por cada kilogramo de café en grano se generan 8 L de agua residual, con una demanda química de oxígeno en un rango de 1.000-100.000 mg/L y un pH entre tres y cinco, lo que clasifica este residuo como altamente contaminante para su vertido en cuerpos superficiales o alcantarillado sanitario.…”
