For municipal wastewater or water treatment facilities, efficient dewatering can be a challenge. Space issues, personnel, and cost are all considerations, and an operation may experiment with a number of techniques before finding one that works.
But dewatering technology from TenCate Geotube is proving to be a simple, cost-effective solution. Geotube2 dewatering technology has been used for a variety of water treatment applications, including lagoon cleanout, temporary dewatering, and even improving the capabilities of drying beds.
TenCate develops and produces materials that function to increase performance, reduce cost, and deliver measurable results by working with our customers to provide advanced solutions. Geotube dewatering technology provides high volume containment and rapid dewatering. There is an 85% to 90% reduction of BOD in the effluent, and the system requires no capital expenditure and no special equipment. Geotube dewatering technology can be used without adding employees or requiring extensive training.
Two Geotube dewatering technology systems are particularly suited for municipal wastewater applications. The Geotube MT is designed to fit in existing drying beds. It is much more efficient than a drying bed, and dewatering continues even during rainy periods. The Geotube MDS (Mobile Dewatering System) places a Geotube dewatering container into a roll-off box that can be easily moved once it is full or once the need for dewatering ends.
The Geotube MDS system requires only the footprint of a long dumpster. It operates like a larger Geotube£ dewatering container, and provides the same filtering efficiency.
There are numerous examples of how effective Geotube dewatering technology can be in municipal applications. In Grants Pass, OR, Geotube dewatering technology was used at a water treatment facility to remove alum sludge from a 2-acre lagoon and a sediment basin. For this project, Geotubes containers were set up in several locations on the facility to take advantage of available space (in one area, the containers were even curved around a bend).
By using Geotube dewatering technology, the facility was able to manage the dewatering process at its own pace, using its existing staff. The process allowed the facility to dry its alum sludge to 28% TS, which allowed easy removal to a landfill.
In Jekyll Island, GA, 400,000 gallons of anaerobically digested sludge had to be removed from the primary and secondary digesters for digester modifications. The sand drying beds available at the facility would not provide the capacity to do this in the time allowed.
