HydroScreen - Model FSRF - Fine Bar Screen Datasheet

The challengeEven when CSO’s and SSO’s are equipped with scum boards, con-siderable quantities of floatables and suspended solids still reach the waters. Sanitary articles, toi-lette paper and synthetics are left caught in the river bank after heavy rain. The waters are biologi-cally and hydraulically “stressed”.The wayAll polluted discharges into recei-ving waters have to be treaded. Floatables and suspended solids can be screened out. This should be done continuously and care-fully to prevent the screenings from breaking up and slipping through the screen mashes. The solutionThe Steinhardt® HydroScreen Fine Bar Screen Model FSRF is a very flat screen. It is installed horizontally at overflows in combined and sepa-rate sewer systems. The direction of flow is from bottom to top. All fine bar screens Model FSRF are made of stainless steel and are normally hydraulically driven. Explosion pro-Fine Bar ScreenModel FSRFtection is not necessary. The control cabinet can be in any chosen posi-tion above ground.The HydroScreen Fine Bar Screen Model FSRF is modular in design and can be installed through small openings (also Ø 600) and moun-ted in the structure. The module is about 65 cm long; the smallest unit starts at 1.30 m with integrated hydraulic drive. Waterwheel drive unit on demand. To prevent scree-nings being carried over the whole length of the screen, each module has rest zones. The screenings are released there by gravity, sink to the floor and are carried by the sewer flow to the WWTP. The minimum installed width starts at 40 cm, extendable in 10 cm steps. The screen height including the hydraulic drive is less than 30 cm when assembled. It is installed horizontally and partially lowered before existing overflow crests so that the screen bars are evenly charged.

In order to trap as much dis-solved matter as possible, the flow velocity between the screen bars is limited to = 1.4 m/s. Removal of screenings begins auto-matically when the HydroScreen Fine Bar Screen Model FSRF is charged. It operates continuously during the discharge and is set to continuous operation.Range of Application • before combined inflows into receiving waters• before storm water inflows into receiving waters• before soil filter systems• before earth and retention basins • before percolations• before difficult-to-clean basinsAdvantages• robust stainless steel con-struction• modular in construction• retrofit through small apertures possible• high cleaning efficiency• safe transport of scree-nings• wiper elements on the pollution-protected side• very flat screen• velocity between screen bars limited to = 1.4 m/s • head loss approx. =10 cm• effective performance approx. 500 l x s-1 x m-2• bio oil• screenings release zone every 65 cm• no re-adjustment • hydraulic drive• optional waterwheel drivePatents pendingStatus: 090624 · Copyright as per DIN 34 · Subject to changes Steinhardt GmbH - 65232 Taunusstein
