Thus, the mixed dewatering technique
with geotextile tubes is interesting, representing
low investment and maintenance
costs, combined with the effectiveness in
gaining solid content over time through
its dewatering technique (Figure 5).
Therefore, the use of geotextile
tubes offers advantages over conventional
dewatering techniques, such as
the need for reduced implementation
area, low cost of implementation of the
technique, good increase in the sludge
solid content, great reduction of volume,
ease of transport and disposal of waste
generated, rain tolerance, use of existing
facilities (sediment pond/drying bed)
and recirculation of percolated water at
the treatment plant.
