The Onset of Dewatering Technique

The ever-skyrocketing demand for expertise in the water field, as a major component in the agriculture and construction industries, calls for an up to date technological tackle. Soil being the major cover on most geographical features may, however, prove to be an obstacle to the implementation of various magnanimous projects owing to the incorporation of liquid components such as water. Separating water or liquid material from a vast area covered with soil is, without doubt, a daunting task, but with the advancement in technology, this might be a story of the past. Through the dewatering technology, water is removed using various water separation techniques including Geotextile dewatering tubes, centrifugation, and a pressurized filter press.

The Geotextile dewatering tubes are filled with sand, silt and clay deposits after which it’s subjected to a highly pressurized system that siphons out the water component whereas the deposits are trapped inside the system. However, they have to be pretreated with polymer to ensure that the particles coagulate, therefore rendering them too large to pass through the woven material. This process is extensively applied in combating beach erosion applications such as lakes, waterways, and in building dikes.

With the ballooning pollution of water bodies such as lakes and oceans for construction projects, dredging has become part and parcel of these outrageous activities. The two main forms are environmental and hydraulic dredging with a major focus on ensuring the safe removal of unwanted deposits and at the same time driving home their development ideals. A hydraulic pump is used to induce maximum pressure in the mixture of water and the sediment, which forms a slurry that is later disintegrated to remove the unwanted deposits. They are then safely disposed of.

However, the successful implementation of the dewatering technique is made possible through the use of Geotextile Dewatering tubes. There are many sizes available including hanging, cubic yard-meter bags and Roll Off Dumpster bags. Hanging bags are offered in different sizes but the common one’s range within 3 by 3 feet, with the top part left open. It is used to test the dewatering performance by pouring the sludge slurry into the top opening, therefore, enabling the user to determine the amount of pretreatment required.

The Cubic Yard-Meter bags are equipped with a flange mounted on the top of the bag and is used in the filtration process of liquids and dewatering the product. Roll Off Dumpster bags is on the other hand used to capture and store the liquids formed as end-products.
