When drill a groundwater monitoring well into an aquifer to take water, some water fills the bottom of the pipe, but not enough to make it work properly. In addition, the water will be filled with sediment and other particles. Well screen will solve these problems.
Water Well Screenis a filter that allows water to enter a pipe from multiple entry points. It can be made of a variety of materials (especially UPVC, HDPE and stainless steel). Water well screen has a large surface area through which water can penetrate.
It is resistant to corrosion because it will come into contact with water. Besides, It has a high strength to keep the surrounding structure intact. The openings of the well screen can be small enough to block the large number of formations around them. The flow of water through the screen would be consistent.
It is recommended to install water well screen for all environmental drilling operations. It helps extend the life of the well and keeps the flow of water unrestricted. Sand and fine powder sand, these fine particles can be filtered out before water is available. Water well screen help to exclude most of this fine material from well water.
Different type of Water Well Screen
Wedge wire well screen
The well screen is made of a variety of SS 304 or 316 and other weldable metals, ranging in slot size from 0.2 mm to 4 mm. The screen and housing are manufactured according to customer requirements with threaded or flange connectors.
Bridge type well screen
It has high-strength by resisting twisting, compression and tensile forces.
-Slot sizes: 1.0 mm to 4 mm
-Wall thickness: 6mm or 10mm
-Diameter from 150mm to 1000mm (can be customized)
-Open area: 6% to 23%
Simple well screen
They are made of rolled and welded perforated plates. The holes are rectangular, arranged in rows, and the long edges of the grooves are aligned with the tube shafts. Slots range in size from 3 mm to 6 mm with wall thicknesses of 3mm to 10mm. And open areas ranging from 14% to 23%.
