Análise da eficiência dos filtros de barro na remoção de cloro residual: uma alternativa acessível para a purificação da água

Abstract

They study of the efficiency of clay filters as water purifiers against residual chlorine is relevant, as it addresses a low-cost and accessible solution for obtaining drinking water where access to treated water is restricted. This study aimed to evaluate the effectiveness of clay filters’ ceramic candle filters, both traditional and with activated charcoal, in removing free chlorine. The experiment was conducted in two phases, where initially the concentration of chlorine and the pH of the water were measured before and after filtration of the contaminated water, with both types of ceramic candles filters, testing its performance at the beginning and the end of their lifespan. The results showed that ceramic candle filters with activated charcoal were significantly more effective in removing chlorine, both at the beginning and end of their lifespan. In contracts, traditional ceramic candles filters show no significant changes in chlorine concentrations and pH, confirming the superiority of ceramic candles filters with activated charcoal. These findings indicate that ceramic candles filters with activated charcoal are a viable and effective solution for improving the quality of drinking water, suggesting their recommendation for domestic environments.
