Underdrains

WEDGE-FLOW product quality is an absolute necessity in the design and manufacture of flat retention screens and underdrains.

Slot sizes of .005″ to .018″ are required for resin, sand and carbon columns. In addition, massive support structure capable of withstanding up to 150 psi and higher pressure differentials is often required. Retaining screens are commonly installed by welding directly to the vessel, and become a vital, integral part of the process.

The importance of engineering expertise and attention to detail during production cannot be understated. Our A.S.M.E. certified welders are in constant communication with engineering during all phases of design and manufacture. It is this understanding of process requirements that guide LEEM from the onset of your project.
