Abstract

Increased transportation activities in this city cause air pollutant emissions, one of which is Total Suspended Particulate (TSP), which has an impact on air quality. This study aims to measure TSP concentration and map its distribution. Data on TSP concentration, air temperature, wind speed, and air humidity were collected using instruments such as High Volume Air Sampler (HVAS), hygrometer, and anemometer. TSP concentrations were modeled with AERMOD based on the obtained data and associated meteorologicalconditions. The results showed that TSP concentrations varied significantly depending on traffic volume and weather, with the highest concentration of 184.8 μg/m3 at point 1 on the first day and the lowest of 9.7 μg/m3 at point 5 on the second day. The distribution of TSP tended to the Southeast, West, and North according to the AERMOD model. Questionnaire results in the sampling areas show that there are still people who are not aware of the impact of TSP pollutants. The conclusion of this study is the presence of TSP pollutants on Tandes Highway, which is influenced by meteorological factors and traffic volume

Abstract

Phosphate and Ammonia rich fertilizer wastes pose potential environmental problems. Depletion of natural phosphate sources encourages the search for sustainable alternatives. This study examined phosphate recovery from fertilizer plant effluent using struvite (MgNH4PO4-6H2O) in a batch vertical reactor. The factors studied were pH, temperature, air flow rate, and solution molar ratio. Struvite is formed by reacting Mg2+, NH4+, and PO43-ions. This study used MgCl2 : waste molar ratios of 2:1, 2.5:1, and 3:1, air flow rates of 0.25, 0.50, 0.75, and 1.00 L/min, and pH of 8, 9, 10, and 11. The MAP solution with the specified molar ratio was introduced into the reactor up to 3⁄4 of its volume. The air flow rate and pH were set according to the parameters. The MAP solution was collected and filtered to produce struvite. Struvite crystals were analyzed by XRF and SEM. Results showed the best phosphate recovery of 67.3% at a ratio of 2.5:1, air flow rate of 1.00 L/min, and pH of 10. This study demonstrates the potential of struvite as a sustainable phosphate recovery solution from fertilizer waste
