Parabolic Screen

Parabolic screens

A parabolic screen is nothing more than a screen with a parabolic curve in it. This curve has several advantages, the dirt easily slides down the screen, meanwhile the water passes through the screen. Because of this, the dirt easily can be removed from the screen, this also can been done by brushes. The dirt can be collected in a bin or a container

Depending on the size of the surface, the screen can handle a large amount of water. The holes of the screen are most of the time between 0,2mm and 2 mm. This technique is especially useful for treatment of wastewater.

Examples of industries in which the screen is used:

There are also vibrating screens available for a better treatment. Because of the vibration the residue easily comes of the screen and it protects the holes from stuffing up
