Screen filter

Typical screen materials include stainless steel (mesh), polypropylene, nylon and polyester.

[citation needed] Self-cleaning screen filters incorporate an automatic backwash cycle to overcome these limitations.[which?]

Their ability to quickly remove contaminants from water before they leach their nutrients make such filters popular choices for recirculating aquaculture systems.

They have also become popular in closed loop industrial systems such as cooling tower, heat exchanger, and other equipment protection applications.

[citation needed] Stainless-steel strainers are used in industrial, municipal, and irrigation applications, and can be designed for very high flow rates.
