The design of geotextile containers for dewatering applications typically requires good retention of the confined fill material solids. This becomes difficult to achieve when the fill material is fine grained and the pore openings are large. Furthermore, the proper retention becomes critical if the confined material is contaminated. Fly ash is one of the fine-grained geomaterials that exhibit b...

The use drying in conditions ensures low energy consumption with achievement necessary results moisture content sediment. increase rate dehydration facilitated by structures using capillary effect to dehydration. designs dewatering sites such elements have b...

Ground water and surface water create a range of problems in lignite mining utilizing surface mining methods. In order to create a safe and economic mining environment, it is essential to carry out mining after dewatering the rock mass surrounding the lignite mines by advance dewatering techniques. This paper briefly describes the ground water regimes including pressure gradients associated wit...

Abstract The impact of dewatering on lime mortars modified using brick dust was studied, as it is particular importance in conservation applications. Dewatering takes place when freshly mixed come into contact with a porous substrate, such or stone, during site construction. Since the process between mortar and its substrate can modify properties, understanding enables pozzolan-modified hydrate...

Sewage sludge proves to be difficult to dewater due to its composition and biological nature, and it is unsuitable for disposal with high moisture content. In the present work, sewage sludge is dewatered by the thermal compression, which shows unique separation advantages of various materials, and the effects of applied temperature and pressure on the dewatering performance are investigated. Th...
