The Fine Screening AquaGuard

Principle of OperationDownload videoIntermittent Operation as an Additional Asset:Intermittent operation of the AQUA-GUARD? Fine Screen minimizes wear and optimizes the screening efficiency in relation to the filter area.The material piles up, thus blinding the screen and increasing the effectiveness and the fineness of filtration.Large quantities of screening material form layers, which can be more easily discharged.This is why Andritz recommends intermittent operation for AQUA-GUARD? Fine Screens:Probes measure the pressure loss (DH = difference between the upstream and downstream water levels) continuously, for automatic control of intermittent filter operation.ApplicationsMunicipal Intake channels Screening at inlet of sewage treatment plants Coarse screening ahead of sludge treatment Coarse screening ahead of biofiltersChemical industry, paper and board, and other industries Water intake (on rivers, lakes, etc.) Coarse screening at pump inlet Industrial process water Waste water Food industry Slaughter houses FeaturesMechanicalOnly one motor for driving the filter elements and the cleaning brush Robust design Simplicity No bearings in contact with the medium Synthetic filter elements Corrosion-resistant finish ProcessContinuous separation without deterioration of the screenings Self-cleaning filter elements Double filtration surface Large flow rate Low pressure loss (?H) Suits numerous applications Can be adapted to existing channels Capable of handling various coarse screening applications High screening capacity
