BAR SCREEN IN STORM BASIN
Contact UsA storm basin or retention basin or storage area is usually equipped with a bar screento remove the heaviest waste from the water, before it ends up in the sewage system or in the sewage treatment plant. water treatment plants.
One of the special features of this retention basin is that Bar Screens are subjected to jerky loads over a short period of time, during which they have to remove as much waste as possible. We'll be sure to advise you on the right hydraulic profile, but also on how to optimize cycle time in the event of significant depth under the paving surface.
Our bar screens for retention basins are perfectly matched: robust, efficient, reliable, simple to operateetc.
BAR SCREENS IN STORMWATER BASINS
Three automatic bar screens type XG12equipped with 40mm air-gap grids, installed in 1400mm wide, 4000mm deep concrete channels. Each screen can handle up to 2.4m3/s with a well-established hydraulic profile, and is equipped with an emergency bypass. Finally, each bar screen has its own FB Procédés-designed electrical cabinetwith variable speed operation.
A automatic vertical bar screen type XG12equipped with a 25mm air-gap grid and installed in a 2000mm-wide concrete channel. This installation must be able to absorb up to 1.30m3/s. To achieve this, we equipped the channel with a weir downstream of the bar screen to optimize the hydraulic profile. The aim is to reduce effluent flow velocity, and thus improve the "screening function".
A automatic vertical bar screen type NG21It can be mounted directly on the wall of a stormwater basin. It is capable of handling more than 1m3/s, and is not placed facing the effluent inlet pipe to preserve the screen (40mm air gap). In fact, the effluent hits a stainless steel box before feeding the bar screen from the side. This metal box is equipped with a manual emergency gate in the event of a problem with the bar screen. Finally, the bar screen/manual screen assembly is accessible via a walkway, the all FB Procédés designs.
Two automatic vertical bar screens type XG1230mm air gap, installed in a FB Procédés secure concrete manhole cover. This manhole is equipped with a flow-breaking wall at the inlet to reduce effluent velocity., from two bypasses protected by 50mm air-gap manual grilles, and finally two main channels, each with an automatic bar screen. Each channel must be capable of handling 1.8m3/s.
