DF(Dual Flow) Type Travelling Screen

The Screening Equipment is installed parallel to the direction of the water flow, and the type in which the water flow direction is from the outside to the inside of the screening equipment is called the DF type. Trash trapped inside the screen equipment is collected by spraying water from the back of the screen panel at ground level as the screen panel rotates. This type of screen is mainly used at geothermal power plants in Japan, and most of the traveling screens delivered overseas are of this type. There is also a CF type that supports water flow in the reverse direction.
