Dewatering Systems: A Guide
If you're looking to invest in dewatering equipment for your construction company, you may be looking for info about the different types of gear. This article will talk you through four of the most common types of dewatering equipment and the circumstances in which they should be used. Read on to find out everything you need to know.
Vacuum filter systems
As the name suggests, a vacuum filter uses a vacuum to remove water from solid material. Once the material has been placed inside the machine, the air within the chamber is pumped out. Because nature abhors a vacuum, any particles of water which are trapped within the material will be expelled into the vacuum.
Filter presses
This gear consists of a tube and a metal plate which has a porous surface. Once the material has been placed into the tube, the metal plate is lowered so it begins to compress the substance. As the plate compresses the material, the pressure forces the water through the porous surface separating it from the material.
Centrifuges
A centrifuge is a container which spins at high-speed. When the material is loaded into this device, the motion of the centrifuge drives the solids against the walls of the container. As this process occurs, any liquid within the material will be drained out. The benefit of using a centrifuge is the speed at which you can quickly dewater a large amount of material.
Drying beds
Drying beds use gravity and the process of natural evaporation to dewater material. Drying beds are typically created by placing drainage pipes on the ground and perforating the surface of each pipe multiple times. The pipes are then filled with the material which needs to be dewatered. As time passes, gravity will cause the liquid to drain from the bottom of the pipe while the holes on the top allow water to evaporate away into the atmosphere.
Wellpoints
Alternatively, you may wish to create a wellpoint dewatering system by excavating several wells around your excavation. Water from the surrounding ground will begin to collect in the bottom of each well. Each well is fitted with a riser pipe through which liquid is pumped out.
If you wish to find out more about the process of dewatering material on your site, you should get in touch with a company which offers this type of gear. A member of the team will be happy to offer you further assistance.
