Performance of fatty acid-modified spent coffee grounds as a potential adsorbent for oil adsorption

Problems caused by fats, oils, and grease (FOG) in sewer systems have escalated over the years. FOG produced from households, restaurants, stalls, and food processing facilities have contaminated water resources through the sewer system. Thus, trace removal of oil from wastewater is a necessary meas...
