The system most used for the treatment of raw water available in water sources
is the conventional Water Treatment Plant (ETA), also known as full cycle station.
During the treatment process are produced waste (sludge), originated mainly
from filters wash and the discharge of the sedimentation tank. These wastes vary
depending on the type and amount of chemical used in the treatment and water
source characteristics. This study aimed to analyze the waste treatment
alternatives generated in the ETA 006 of Palmas TO, with main focus on
dewatering of waste through the application of synthetic polymers and geotextile
filtration. First were characterized the waste generated at ETA 006, being then
made bench tests simulating flash mixing conditions and
clarification/consolidation in jar test and geotextile filtration. Were used different
dosages of synthetic polymers non-ionic, cationic and anionic. The results
showed that the use of polymers in the dewatering of sludge in the geotextile was
efficient, reducing turbidity values and total suspended solids (SST) in the
sample. The polymer that showed the best result in the dewatering process was
the cationic. |
