Pumps being used to dewater a spillway at Baldhill Dam. Dewatering / d iː ˈ w ɔː t ər ɪ ŋ / is the removal of water from a location. This may be done 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.
These pumps, often submersible and powered by electricity, can access water reserves located much deeper than shallow wells, ensuring a consistent supply even during periods of drought. They include different kinds of pumps, most of them submersible pumps: Hand pump, manually operated; Injector, a jet-driven pump; Mechanical or rotary lobe pump ...
The point is simply hammered into the ground, usually with a tripod and driver, with pipe sections added as needed. A driver is a weighted pipe that slides over the pipe being driven and is repeatedly dropped on it. When groundwater is encountered, the well is washed of sediment and a pump installed. [17]
The well is equipped with electrical instrumentation to detect the level of sewage present. When the sewage level rises to a predetermined point, a pump will be started to lift the sewage upward through a pressurized pipe system called a sewer force main if the sewage is transported some
The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination ...
A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1] It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface. The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas.
The single water injection booster pump (221 m 3 /hr, 1,379 m (139 bar) differential head) took its suction from the discharge of the water injection pumps and discharged to the 5,000 psi (345 bar) manifold and wellheads. There were eight water injection wells, each well had a capacity of 15,000 BWPD (99.4 m 3 /hr). [3]
A spiral pump. A spiral pump, sometimes called a Wirz pump or incorrectly Wirtz pump, is a low lift pump which is composed of a long piece of metal plating, which is wound into a coil and sealed at the top and back extremities so as to resemble a cylinder. The outer cavity serves as the inlet, while the inner (partial) tube serves as the outlet.
