It is the most useful and economical among solid waste filters. By using two drum filters with
cloths with different mesh openings, all suspended substances in the water (such as inedible

feed, feces, etc.) can be cleaned. It can be used especially in geothermal enterprises engaged
in commercial production.

6.2.2. Bag Filter

It is a type of filter that works by filtering the water collected from fish tanks through a cloth

bag. By using cloths with different mesh openings, smaller particles can be separated from the
water. Cloths need to be cleaned or changed periodically. Otherwise, clogged cloths may

cause the system to clog.
