Cheaper, swifter dewatering Recognising that dewatering is a major obstacle encountered by dredging contractors all around the world, Wisconsin-based company IMS has purchased patent pending GeoPool dredge dewatering technology. Claimed to be inexpensive, reusable and scalable, the technology, in most cases, does not require polymers. It was invented by an IMS Versi-Dredge customer and underwent successful trials in the USA and Europe. Several GeoPools have since been sold. The GeoPool system operates continuously in a two pool configuration. One pool is cleaned out while the other is actively filled. A single Y-fitting, with two knife gate valves, controls flow to each pool. The system comprises a series of 10ft (3m) wide x 6ft (1.8m) high dismountable hot dip galvanised steel frames. These are linked together to form a circular pool-like structure that is lined with IMS’s unique GeoFabric, a different material to geotextile tube fabric. A hydraulic dredge pumps the slurry directly into the GeoPool, the water from the slurry permeates through the filter fabric and the solids are retained in the pool. When a pool is full, it is ready for dry down, which takes three to four days depending on material. Materials, such as ultra fine clays, may take longer and might need a polymer to improve effluent clarity. When the pool is dry, ‘collapsible cleanout gates’ are dropped, and tracked earth movers can enter the pool and remove the dry and stackable solids. During dry down, the dredge discharge is diverted to a second pool to allow for continuous operation. In addition to standard dewatering through the filter fabric, ‘dump doors’ allow for rapid bulk dewatering of clear surface water to speed up the entire process. IMS GeoPools are reusable and thus less expensive than geotextile tubes for medium to large projects (a small GeoPool configuration costs approximately the same as ten large non-reusable tubes). GeoPools can also handle a much larger volume of material; it would take between 10 and 40 geotextile tubes to equal the dewatering capacity of one GeoPool. IMS has financing available for the purchase of one or more GeoPools and is seeking dealers around the world for the system.
