Dewatering | McLanahan

Dewatering through filtration separates liquids from solids by introducing a medium through which only the liquid can pass. Water and other liquids are removed from the slurry, draining out through a permeable barrier or filter media, and leave a trapped cake of drier solids that are too large to pass through the barrier or filter media.


Wellpoint Method of Dewatering Excavations. 1) A series of wells of required depth are created in the vicinity of the excavated area from where the water has to be pumped out. The wells are arranged either in a line or a rectangular form where the wellpoints are created at a …


What is Dewatering? Dewatering is the process of removing groundwater and surface water from a construction site. Usually, this procedure is carried out before excavation, or the groundwater level is lowered on site. Objective of Dewatering. There are two main objectives of dewatering.


Some applications have experienced a moisture content as low as 7% with McLanahan Dewatering Screens, but final moisture content is dependent on both surface moisture and inherent moisture. When reporting moisture by weight (kg water/kg pulp), the specific gravity of the soilds also plays a factor, with higher specific gravity materials showing lower moisture contents.


Special systems must be used to remove the excess water from slurries containing things like, grit, frac sand, metal ore, and other substances. They're most popular used as coal and sand dewatering screens. One of the most important components of such systems is the dewatering screen.


Sand Dewatering Screens have been tested and proven to remove up to 40% of the water and up to 80% of the organic material that remains in the recycled sand. In all cases, this creates a drier, cleaner product that can be reused more quickly with less conditioning.


Removal of large quantities of water for dam abutments, cut-offs, landslides etc. Large quantities of water can be drained into gallery (small diameter tunnel) and disposed of by conventional large – scale pumps. ... The inner well casing has a perforated screen over the depth requiring dewatering and terminates below in 1 m of unperforated ...


In coal mines, conveyor dewatering systems remove water from the coal stream to improve coal quality. When material has been transported any distance on a belt conveyor it starts to divide, with larger lump content moving to the top and the slimes and water to the bottom.


Various cloth geotextiles and screen mesh filter options are available to achieve desired flow rates and micron levels. Utilizing the technological advantages of screen and non-woven polypropylene materials, dewatering liners are an effective avenue for draining liquids from sludges while leaving solids for disposal or other uses.


The difference between dewatering screen manufacturers is small tweaks to a century-old design. (1) We're the only manufacturer to include screens on the sidewalls, which exposes the sand to more screening action to remove more moisture. (2) Combined with a higher g-force, our screens allow deeper sand depths to physically squeeze out more water.

The ground water is drawn by the pump into the well-points through the header pipe and discharged as shown in fig. 2.3. The well-points are usually installed with 0.75m – 3m spacing. This type of dewatering system is effective in soils constituted primarily of sand fraction or other soil containing seams of such materials.


In addition to sampling the discharge of the screen, samples were taken at two points along the length of the screen. After 10 minutes of screen operation, dewatering was substantially complete in the first 3 feet of screen length (fig. 3). Blinding rapidly increased the length of screen required to remove the bulk of the water.
