Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The study optimized the coagulation-flocculation process using Vigna radiata extract (VRC) to reduce turbidity, PO4, and NO3 from wastewater, analyzing factors like dosage, pH, stirring time, and speed. The experimental design optimized coagulation parameters: pH: 11, coagulant dosage: 50 ml/L, stirring time: 43 min, and stirring speed: 56 rpm; resulting in 97.51%, 96.86%, and 56.98%, for turbidity, PO , and NO removal, and generated a sludge volume of 9.0 ml/L. Real aquaculture wastewater treated at pH 7, with the optimized conditions, had a maximum of 76.91%, 12.56%, and 51.8% for turbidity, PO , and NO removal, respectively. A comparison study of the natural coagulant with the alum and FeSO4 as chemical coagulant showed similar results; however, the sludge volumes generated by the chemical coagulants were significantly higher than that of the natural coagulant. The study suggests that VRC can effectively treat wastewater from the aquaculture industry through adsorption and charge neutralization mechanisms
