Dredging is an extremely Environmental focused  process used to remove accumulated sediment from the bottom, and in some cases, on mining and Industrial water bodies, the banks or sides of a river, lake, stream or other body of water. A specialized piece of equipment called a dredge creates a vacuum that sucks up and pumps out the unwanted sediment and debris. Environmental dredging is sometimes necessary due to sediments in and around industrial areas which are frequently contaminated with a variety of pollutants introduced to waterways from point sources such as sewer overflows, municipal and industrial discharges or spills.

Dewatering can be done through:

The Geotube where the technology works by allowing sludge to be filtered through the unique dual filament polypropylene fabric, while retaining a solids. As slurry is pumped into a Geotube unit, the process mostly requires added chemicals to improve dewatering. The addition of the polymer to the sludge is necessary to flocculate the sludge and allow the Geotube technology to dewater as effectively as possible.

Geotube units are durable and can be stacked to maximize space or fabricated to fit in mobile roll-off containers which can be transported around a property or location. The unit comes in sizes to contain 100m³ to 500m³ of wet sediment slurry or sludge.

The Gravity Filtration Dam (GFD) can be cleaned out and re- used until project completion once constructed.  The amount of geotextile material required will be on average 4 times cheaper than normal dewatering options currently being used, as the GFD’s material can be used 4 to 5 times before replacement is required. Drying times for the sediment are 20% to 25% faster than normal dewatering bags due to effective open drying surface.

The required civil works area can be greatly reduced, since the dams can be used indefinitely and cleaned out on a regular basis.
