Filtração em cerâmica microporosa apicada à remoção de cor e turbidez de água para abastecimento público

Resumo

A 60 cm-high, 6 cm-diameter, 1 cm-thick ceramic filter with porosity of 0,1μm was the object of this research which aimed to study the removal of color and turbidity from raw water. The device had 0,113 m2 of external surface and was installed inside an acrylic column 110 cm high and with inner diameter of 23 cm. This column had a volume of 41,5 L. Raw water was collected from a … where turbidity varied from 2,3 to 2,8 NTU and apparent color from 1,82 to 3,26 PtCo. Three different application rates were applied (1,82, 3,16 e 4,49m3/m2.dia) accomplishing three filtration runs for each one of them. Water samples were collected from influent and effluent of filter each time that head loss raised in 5 cm, until 20 cm of head loss were completed. Results showed 75 to 80 % efficiency in turbidity removal, resulting in values between 0,53 to 0,58 NTU for the last run for each filtration rate applied. In the other hand, system doesn’t show efficiency for the removal of color.
