Chain Driven Screens are a type of primary treatment equipment used in the wastewater treatment process. These screens are used to remove large solids and debris from wastewater before it goes through further treatment processes.
Chain Driven Screens consist of a series of metal chains with evenly spaced bar screens attached to them. The chains are driven by a motor and rotate at a slow speed to ensure that solids and debris are caught by the bar screens. The captured solids are then lifted out of the wastewater and transferred to a collection bin or conveyor for disposal.
Chain Driven Screens are commonly used in municipal wastewater treatment plants, industrial wastewater treatment plants, and in pretreatment processes for food and beverage production facilities. They are particularly effective at removing large objects such as sticks, rags, and plastics that can cause damage to downstream equipment or clog pipes.
The size and spacing of the bar screens can be customized based on the specific application and the size of the solids being captured. In addition, the screens can be made from various materials such as stainless steel, carbon steel, or plastic, depending on the wastewater characteristics and the desired level of durability.
