Static Bow Screen (GST)
The Static Bow Screen model GST is a simple and economical solution for separation and screening of solids from process water and wastewater. Static Bow Screens are free standing units that use a wedge-wire screen element for solids removal. The wedge-wire screen element is formed with a curved radius and is mounted in a stainless steel housing. This allows for maximum hydraulic capacity and the driest possible solids after separation. The GST Static Bow Screen is offered with optional hinged cover and external washing bar that can be fitted with a solenoid valve for automated washing of the screen element.
