Screen filter


Screen filter

A screen filter is a type of filter utilizing a rigid or flexible screen to separate sand and other fine particles out of water for irrigation or other applications. These are generally not recommended for filtering out organic matter such as algae, since these types of contaminants can be extruded into spaghetti-like strings through the filter if enough pressure drop occurs across the filter surface. Also, screen filters do not have the capacity to filter large amounts of contaminants as do media filters. Typical screen materials include stainless steel (Mesh), polypropylene, and nylon. Similar devices with larger openings designed only to keep out large objects are called strainers.
