Water treatment plant residues requires special attention due its high potential os pollution and
contamination if disposed in the natural environmental. The technology to treat the residues
depends on technical and economic criteria, giving special attention on the quantitative and
qualitative aspects of each alternative. This work focused on the treatment of residues produced
in Double Filtration Water Treatment (Porto Nacional/TO, Brazil Plant), in order to study
different types of synthetic polymers (cationic, anionic and nonionic) to both clarify in a jartest
device and thick the sediment in Imhoff Cone. The results show that the cationic polymer was
the most efficient in terms of the supernatant turbidity and the degree of thickening. |
