Análise da eficiência de filtros domésticos de areia, na remoção de turbidez de água para fins não potáveis

Abstract

This research aimed to evaluate the effectiveness of filters constructed with PET bottles and layers of sand with different grain sizes in reducing the turbidity of synthetic water. The research is justified by the need for accessible and sustainable solutions for communities lacking adequate sanitation infrastructure, considering the challenges associated with the rational use of water resources. The methodology included the fabrication of filters with recyclable materials and experimental tests to measure the initial and final water turbidity using

a turbidimeter. Statistical analysis of the results involved calculations of mean, variance, and standard deviation, as well as comparisons with similar studies. The filters demonstrated average turbidity reduction rates exceeding 95%, showcasing high efficiency even under conditions of elevated initial turbidity (500 NTU). The results highlight the technical and environmental feasibility of using recyclable materials in household filters. However, the study acknowledges limitations, such as the absence of microbiological analyses and the long-term durability of the materials. Future research is recommended to address these gaps and explore hybrid applications to expand the reach of this technology.
