Screen filter
From Wikipedia, the free encyclopedia
For a device that fits over a computer screen, see monitor filter.
A screen filter is a type of water purification using a rigid or flexible screen to separate sand and other fine particles out of water for irrigation or industrial applications.[1] 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. Typical screen materials include stainless steel (mesh), polypropylene, nylon and polyester.[citation needed]
