A Case Study of Dewatering Biosolids Using Stacked Geotextile Tubes
A case history of the Savanna Street Wastewater Treatment Plant (WWTP) in Jackson, MS is presented. Four stacked tiers of 228 geotextile tubes were used to process 83,500 dry tonnes (92,000 dry tons) of biosolids sludge, from stormwater lagoons operated by the WWTP, for off-site disposal. Following a successful pilot study in which the feasibility of attaining a 25 percent solids concentration within a 30-day drying period was demonstrated, two lined cells, each with a footprint of over 2 hectares (5 acres), were constructed. Strength testing of the biosolids sludge was performed. The slope stability of the stacked geotextile tubes was modeled and analyzed for multiple geometries and failure modes. This paper describes the design and operational challenges involved in using stacked tiers of geotextile tubes to dewater biosolids sludge with high water content. This case study will provide a good background for facilities considering implementing this dewatering technology.
