SCREENING FOR MEMBRANE BIOREACTOR PLANTS – MBR
Description and operation
Definitive Ecology’s INFLODRUM is a fine rotary drum screen for municipal and/or industrial treatment plants, designed for medium-high flow rates. This machine finds its ideal area of application in the presence of high concentrations of suspended solids, F.O.G. substances and fibrous products, thanks to its ability to handle wastewater of all types in both municipal and industrial environments. The wastewater enters the machine via a pipeline, by gravity or pump feed. The liquid subsequently enters the drum via a quiescent tank with a spillway.
Fine screening is performed with a perforated plate screen or self-cleaning wedge wire with aperture / spacing of between 0.25 mm and 4.5 mm. A complete range of accessories provides the opportunity to customize each machine to match various plant requirements; one accessory of note is the shaftless screw compactor for screenings volume reduction of up to 40% to reduce the significant water contents.
The machine is made in two models: RD for medium and high flow rates, and MRD for low flow rates.
