Self-Cleaning Filters for Pre-Treatment of Membrane and UV Water Treatment Systems

摘要

The removal of suspended solids isrnnecessary to protect membrane systems andrnprevent the “shadow effect” in ultraviolet (UV)rntreatment systems. Recent field data has shownrnthe effectiveness of automatic self-cleaning filters inrnremoving suspended solids down to less than 3rnmicrons in size without flocculants, pm-coats orrngranulated media. Tests have demonstrated therncomplete removal of particles 10 micrometers (alsornmicrons or pm) and larger with self-cleaningrnweavewire screen filters and particles 3 micronsrnand larger with thread filter technology.
