Origin
The origin of the bar screen can be traced back to ancient times when people used natural materials such as reeds and grasses to filter water. Over time, the design of the bar screen evolved, and today, it is a highly efficient mechanical device used in water treatment plants and wastewater treatment facilities around the world.
