Some Of The Dewatering Equipment

By Helen Wagner


A building of any kind requires being put up in a dry area thus a feasibility study is required to determine the extent of water levels in the surrounding area. This means that before any construction commences, you are required to bring in professionals to check for water underground. If this is not done, you may put up a building only for it to fall after a while. The article highlights some dewatering equipment.

Centrifugal pumps are some of the most common ones. It has an impeller that drains all the pressure out of the pipe allowing for the water to rise due to the atmospheric pressure. The pimp encasing can be filled with liquid to avoid it being inhabited by air and gases that may prevent the rising of the water into the pump.

There are also the displacement pumps. As the name suggests, the air in the cylinder is displaced by the aquatic as it goes into the chamber. The piston, when pushed, exerts force through the chamber forcing the aquatic to go out through the other end. The diaphragm pumps are not all that different. The aquatic is pushed out when the diaphragm moved downwards.

Airlift pumps are also used for the lifting of the water. They, however, do not have any moving parts. There is a long perpendicular pipe that connects with compressed pressure. The pressure, once released, is able to push the aquatic up and all the way to the area of discharge. They may actually be the easiest kind of pump to use there is.

When you hear of centrifuges, you may mistake them for centrifugal pumps. They are actually not the same thing. The centrifuges consist of a bowl that keeps spinning at a very high speed. The main aim of a centrifuge is to separate the liquid from the solid. Due to the high speed, the liquid is pushed into one direction while the solid remains stuck on the walls of the bowl.

Vacuum filters are another way of dewatering. This is mainly used for removing liquids from solids. They save money that would have been used in heat treatment. This is saving money especially if the solid in question was to be disposed of in the long run. It may difficult to dispose of some solids especially when they still have some liquid in it.

Filter pressures work more or less like the centrifugal pumps. Liquids and solids are separated by using porous plates. The solid part of it is restrained in the pores of among two or more plates. The liquid is forced into the small holes either by the continuous pressure that pushes the plates organised or by force from the solids which have been forced into cavities.

Finally, there is the sludge lagoon. This is used in preventing water from any sort of liquid from seeping onto the surface. It may be left for almost a year or more when the liquid has naturally evaporated, or the buildings foundation is built on there.
