A decontamination machine is a piece of equipment used to remove debris attached to a debris screen. It is a water treatment device capable of clearing variously shaped debris from fluids and can be widely applied in pumping stations, hydropower plants, urban sewage treatment, water supply industries, and power plant intake. Additionally, it can serve as a preliminary screening device in the wastewater treatment processes of industries such as textiles, food processing, papermaking, and leather, making it one of the solid-liquid separation equipment.
