BARRETO-TORRELLA, Sarah; PEREZ-MARIN, Raúl  and  RECIO-RODRIGUEZ, Yamila. Water quality and filtration rate obtained with household clay filter “tradiFILTRO”. RTQ [online]. 2020, vol.40, n.3, pp. 564-579.  Epub Nov 20, 2020. ISSN 2224-6185.

To evaluate household clay filter tradiFILTRO performance, under field conditions, samples of water processed by National Enterprise of Analysis and Technical Services of physico chemical characteristic were statistically processed, as well as filtration rate data taken by Integrated Center of Water Technologies in evaluation process of filters quality. Concentrations of nitrates, nitrites, total coliforms and Escherichia coli were foundin raw water, higher than those required for drinking water sources. The removal of turbidity was 97 - 100%, the log10 reduction of total coliforms and E. coli were 3,26 and 2,72 respectively. The filtration rate was found in the range of 1,65 - 3 L / h (x ̅ = 1,7 L / h). An increase in pH and carbonates was found, which does not put the health of consumers at risk.

Keywords : drinking water; household clay filter; filtration rate.
