Abstract:
ABSTRACT The present work objective is to study the feasibility of spent coffee grounds (SCG) biochar as an adsorbent for color removal. SCG were collected from a local cafeteria. The composite SCG sample was prepared for biochar production by washing with distilled water and drying at 100oC for 24 h in a hot air oven. The prepared spent coffee grounds were filled in mud pot fitted with a lid and introduced into the muffle furnace at temperatures 300,400 and 5000C for 4hrs for pyrolysis process. The SCG biochar (BC300, BC400 and BC500) was sieved and the SCG biochar of 0.3mm size was used in the present work. The optimum dosage for BC300 and BC400 was found to be 3.3g, and for BC500 it was found to be 3g. The optimum pH for BC300 was found to be 2, for BC400 and BC500 it was found to be 1. Coffee pulping wastewater was collected and its initial parameters were measured. The initial COD was found to be 19840 mg/L and after treatment under optimum conditions, the final COD was found to be 16480mg/L, 110240mg/L and 11200mg/L for BC300, BC400, and BC500 respectively. The initial BOD was found to be 4134 mg/L and after treatment under optimum conditions, the final BOD was found to be3400mg/L, 2200mg/L and 2400mg/L for BC300, BC400, and BC500 respectively. The initial color concentration of the coffee pulping wastewater was found to be 0.47 mg/L and after treatment under optimum conditions, the final color concentrations were found to be 0.29mg/L, 0.41mg/L and 0.39 mg/L for BC300, BC400, and BC500 respectively. The efficiency of BC300, BC400 and BC500 in color removal was found to be 38.28%, 45% and 17.49% respectively. Keywords: Biochar, Color, Spent coffee grounds, Coffee pulping wastewater
