Selective Adsorption of Nutrients and Pharmaceuticals from Source-separated Human Urine Using Modified Biochar
Abstract
The primary source of nitrogen and phosphorus in municipal wastewater treatment plants is human urine. One of the primary concerns associated with the use of urine-based fertilizers in agriculture is the presence of micropollutants, including pharmaceutical residues, which are co-excreted with nutrients in urine. The present study experimented sewage sludge biochar pyrolyzed at a temperature of 700°C and its modified form using dimethyl sulfoxide (DMSO) for selective adsorption of antibiotics in human urine. The adsorption isotherm and kinetics can be adequately described by the Langmuir and pseudo-second order, respectively. The maximum adsorption capacities of azithromycin, sulfamethoxazole, trimethoprim, and tetracycline were found to be 385, 270, 357, and 1,000 μg/g, respectively.
The study focuses on the utilization of human urine as a fertilizer and the concerns associated with the presence of pharmaceutical residues in urine-based fertilizers. The researchers used modified biochar which poses a strong interaction with antibiotics in urine. This study provides valuable insights into the separate adsorption of nutrients and antibiotics from urine and the mechanisms involved. It contributes to the understanding of the closed-loop nutrient cycle and circular economy.
