Dewatering

Dewatering / d i w t r / is the removal of water from solid material or soil by wet classification, centrifugation, filtration, or similar solid liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes. Construction dewatering, unwatering, or water control are common terms used to describe

Dewatering Methods Wellpoints The wellpoint consists of a slotted or perforated pipe which is covered with a screen mesh. At the foot of this pipe is an orifice which permits jetting of the pipe into the ground during installation. A well point dewatering system consists of a series of closely placed small

DEWATERING CONTROL OF GROUNDWATER

A number of methods are available for controlling the inflow of water into an excavation the The inner well casing has a perforated screen over the depth requiring dewatering and terminates below in 1 m of unperforated pipe which may serve as a sump for any material which passes the filter. After the slotted PVC or metal well

J214ST GmbH + KG Dewatering Screen

The basic movement of dewatering screen is linear with horizontal mounting or upward inclination. With a high angle of attack and high acceleration, extremely low residual moisture values can be achieved. Based on the low conveying speed a high product layer will be created at the screen deck end, this gives an additional dewatering effect.
