摘要：	Through the application case presented, it is possible to realize that dewatering in drying beds would not provide the effective cleaning and dewatering of the sludge from the consolidation ponds in time. Furthermore, mechanical dewatering techniques, which would be effective for the purpose of cleaning the ponds over time, were not viable, representing high investment and maintenance costs for the service. 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.
