| Abstract | ||
| Technologies for biosynthetic nanoparticles are crucial and efficient in treating wastewater in an economical and ecologically responsible manner, outperforming conventional techniques for producing chemicals and other tangible materials. The green biosynthesis of silver nanoparticles (AgNPs) utilizing Fischirella muscicola algae was the subject of the manuscript, where the properties of biosynthetic nanoparticles were studied and characterized using some modern technologies. Then, they were exploited for the purpose of designing a laboratory treatment plant to add them to a double filtering system using a 1% solution of AgNPs to the point of saturation, as well as using a filter without nanoparticles as a control model for comparison. The results of wastewater treatment of the Khosar River, when using nanotherapy, indicated a relatively high efficiency in improving water quality compared to the control mode. The removal rate was high for chloride, lead, and nickel ions in addition to the organic load, reaching 61.11%, 50.0%, 86.67%, and 65.96%, while the removal rate was low in the control model (8.333, 33.33, 46.67, and 6.383%, respectively). In addition, the removal rate for both the total number of bacteria and fecal coliform bacteria was high reaching 98.95 and 98.52%. Moreover, the removal rate in the control model was also high reaching 87.36 and 91.52% due to the filtration process for the filter used in the study. | ||
