IFM Series of Internally Fed Rotary ScreensSource: IPEC
The IFM, from IPEC Consultants, meets the needs of wastewater managers in preventing trash and inorganic solids from entering their bioreactors. The fine separation capability (down to 250 micron) of this unit, make it ideally suited to protect MBR’s and to remove those irregularly shaped solids that work their way through downstream processes
IPEC started in 1979 as a company offering assistance to industry on selection of cost efficient methods of air and wastewater treatment.
Since 1982, IPEC has designed and built solid/liquid separation devices, which became sole focus of the company in 1989. IPEC manufactures an extensive line of primary effluent fine screens, scum screens, dewatering conveyors, sludge thickeners, washer/compactors and bagging equipment.
IPEC’s newest member of internally fed screening devices, the IFM, will be on display at WEFTEC in San Diego from October 15 – 17, in Hall B, at Booth 6443.
The IFM meets the needs of wastewater managers in preventing trash and inorganic solids from entering their bioreactors. The fine separation capability (down to 250 micron) of this unit, make it ideally suited to protect MBR’s and to remove those irregularly shaped solids that work their way through downstream processes. Even though this unit deals with the nastiest of contaminants, the IFM performs as a clean and trouble free operation. The addition of the IPEC PLT, solids washer/compactor, leaves only fecal free and odor free solids for disposal.
General IFM Specifications:
IFM Series of Internally-fed Rotary Screens are designed for the high flow rate/low solids content of municipal sewage. They are compact, operator friendly, clean in place and fully enclosed to contain vapors. The housing is a unitary body of plate and structural members that provides a stable platform for mounting of the screen cylinder. The IFM can use screen media of wire mesh, wedgewire, perforated plate or combinations. Selection of screen filament is based on the requirements of the downstream treatment process. Selections range from Wire mesh (200 –1000 microns) generally used for fine screenings, coarser applications (2mm - 10mm) typically utilize perforated plate. Wedgewire can be used for solids removal in a wide range of slot openings.
The influent enters an engineered headbox, where the flow energy is dissipated, and is evenly distributed onto the interior sidewalls of the drum. Solids are retained on the screen surface and the liquid flows radially through the screen openings. Splash guards direct the liquid filtrate to a central drainage area, and the solids are transported axially, by flights, to the open end of the drum. The rotation of the drum allows the entire screening surface to be continuously or intermittently washed by a fixed, external, spray bar fitted with a bank of spray nozzles, truly a clean in place wash system.
