What's the difference between a screen and a grille?

The difference between screen and grille: different uses mean different things.

First, the use is different:

The screen is made of raw materials such as mulberry silk, metal wire or synthetic fiber, and has uniform and stable pores on the surface. It is an industrial fabric with screening and filtering function. The mesh of the screen is customarily called mesh.

Grille consists of a group (or groups) of parallel metal bars and frames. ; It is obliquely installed at the inlet of water intake channel or water collection well of water intake pump station to intercept coarse suspended solids and impurities in sewage.

Second, it means different:

The specifications of screen are often expressed by the number of holes per unit length (mesh number) and also by the width of each hole. The national standard of China is expressed by the number of holes per cm, such as 20 holes/cm.

The amount of pollutants that can be intercepted by grids varies greatly with the spacing between grids and the nature of water. Generally speaking, the principle is not to block the water pump and the treatment equipment of the water treatment plant.
