New automatic filters integrate two stages into a single vessel

The CSF-ABW two-stage backwash filter (photo) is a fully automatic water-filtration system that is contained within a single vessel. The first stage is a coarse-screen flushing filter with a 1/8–1/2-in. slotted screen for quick self-cleaning. The second stage is a finer filter with screening capabilities down to 75µm. These new automated filters offer direct filtration of a dirty water source, such as river water, lake water, industrial wastewater, dirty cooling water and many more. For simpler operation and maintenance, there are few moving parts inside CSF-ABW filters. — Tekleen Automatic Filters Inc., Los Angeles, Calif.
