Abstract

Aiming the cyanobacteria removal, the present research utilized the upflow double filtration as water treatment system (continuous backwashing filter and conventional ascendant filter), with filtration rate of 150 m³ (m² d)-1 in both filters. The treatment tested was: coagulant addition in both filters inlet. The parameters evaluated were: turbidity, apparent color, true color, dissolved organic carbon (DOC), absorbance at 254 nm, chlorophyll a, cyanobacteria density and loss of load. The double filtration system has proven efficient to the cyanobacteria removal and worthwhile in terms of operational services, once it lessens the second filter washings, which allows obtaining a filtration period up to 293 h and a significant increase in the effective water production.
