Catenary Screens are a type of primary treatment equipment used in wastewater treatment plants. They are designed to remove large debris such as sticks, leaves, plastic, and other floating materials from the wastewater stream before it enters the next stage of the treatment process.
Catenary Screens consist of a series of stainless steel mesh screens suspended from a catenary cable. The wastewater flows through the screens, and the debris is caught on the screens' surface. The screens are periodically cleaned by a scraper blade that removes the debris and deposits it into a dumpster for disposal.
Catenary Screens are often used as a first stage of treatment for wastewater treatment plants that receive large amounts of solid waste or where there is a risk of damage to downstream equipment due to large debris. They are also useful for protecting marine and freshwater environments by preventing debris from entering the waterways.
Catenary Screens come in a range of sizes and configurations to suit different wastewater treatment applications. They are typically made from durable materials such as stainless steel or corrosion-resistant plastics to ensure long life and low maintenance requirements.
