Abstract
Magnetite (Fe₂O₄) nanoparticles represent arevolutionary solution to the alarming water pollution crisis,offering an innovative and highly effective approach toremediate pollutants in domestic wastewater. This studyevaluates their practical application in the Chilca River inHuancayo, Peru, a water body severely affected by untreateddischarges that pose a serious risk to public health andsustainable development. Focusing on key parameters such asChemical Oxygen Demand (COD), turbidity, Total SuspendedSolids (TSS) and oils and fats, the results showed significantreductions: COD from 442.5 mg/L to 135.2 mg/L, turbidity from98.5 Nephelometric Turbidity Units (NTU) to 50.2 NTU, TSSfrom 120 mg/L to 62 mg/L and oils and fats from 45.2 mg/L to11.3 mg/L, while maintaining stable pH levels. Regressionanalysis confirmed that the concentration of magnetitenanoparticles plays a key role in process efficiency. Thesefindings not only validate the efficacy of this technology in highpollution contexts, but also highlight its scalable and sustainablepotential to address similar problems in polluted water bodiesworldwide, contributing to improved water quality and publichealth.
