Sludge Dewatering

TitanTubes® are designed to be filled hydraulically with sludge utilizing a dredge. Sludges commonly dewatered using geotextile tubes include municipal, industrial, agricultural, animal, and hazardous.

The porosity of the fabric allows excess water to drain from the tube resulting in an effective and relatively inexpensive method of dewatering. Polymers are often injected into the sludge to cause the solids to cling together (coagulate) and, thus, release the water. As the excess water drains from the sludge, retained volume is reduced permitting the tube to be refilled multiple times. Once the tube has been filled to capacity, the material will continue to dewater for a period of time, depending on the consistency of the material, use of polymers, and climatic conditions. Once desired consolidation has occurred, the tube can be slit open and the dewatered material transported to a landfill for disposal.

Since no capital investment is required, the use of TitanTubes® is often the most cost-effective and practical way to dewater sludge. Because available space for traditional dewatering methods is not always available, TitanTubes® are an attractive option since they require a relatively small footprint and may be multiple stacked. Quite often, all the space required is the corner of a parking lot.
