Introduced over 25 years ago, the Hycor Rotostrainer® screen is the original self-cleaning wedgewire screen. With over 700 installations, it is a proven fine screening technology for municipal wastewater treatment plants and many industries with several application capabilities.
In wastewater treatment plants, the Hycor Rotostrainer® is renowned as an externally fed rotary screen for pretreatment. It is also the industry choice for scum screening. Industrial users, such as meat processors, food processors, tanneries, textile mills, petrochemical plants, and recyclers, rely on it for product recovery and wastewater treatment.
How the Hycor Rotostrainer® Works
The screen is externally fed so that influent is directed under a baffle, then upward and over the length of the cylinder. The natural action of wastewater cascading through the screen creates a powerful backwash, which results in a continuously clean surface. Solids are caught on the outside of the screen surface and are removed by a tensioned doctor blade.
