Rotating drum screens with perforated plate screen media are the most successful solution for screening prior to an MBR system. Because Rotoshear® PF uses Rotoshear®’s base structure, it is the most reliable and highest capacity screen for an MBR plant.  More than 15 MBR plants use Rotoshear® PF as their membrane protection. It has been incorporated at more than five major installations in the country with more than 5 MGD (3500 gpm) flow rate per screen. That is a claim no one else can make. Unlike center-flow band screen technologies, Rotoshear PF™ does not allow bypass of solids larger than the screen opening. Plants using other technologies often face problems with membranes fouling. As a result of those problems, several plants switched to Rotoshear PF™ to eliminate their concerns about membrane fouling.

Introduced over 25 years ago, the 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 Rotostrainer® unit is renowned as a fine 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.

With more than 1,000 installations, Rotoshear® is a proven high-capacity fine screening technology for municipal wastewater treatment plants and many industries for various applications. In wastewater treatment plants, the Rotoshear unit is renowned as a fine screen for pretreatment and primary treatment to replace primary clarifiers. They are also used as sludge screens. Industrial users, such as meat processors, food processors, tanneries, textile mills, petrochemical plants, and recyclers, rely on it for product recovery and wastewater treatment. Pulp and paper mills use it for fiber recovery and rejects handling.
