➤ Equipment and system solutions for application in combined ➤ ➤ and separated sewer systems Advanced combined and stormwater treatment in municipal combined sewers is a main issue with regard to sustainable environmental and water protection. The building of new wastewater treatment plants and the upgrading or refurbishing continuous wastewater discharges has significantly increased the quality of many watercourses. Despite all of these efforts however, there are still ecological problems caused by floating and coarse material discharged from the sewer system into the waters in a...

➤ Combined and stormwater treatment ➤ ➤ ROTAMAT® Storm Screen RoK 1 installed behind the overow sill Product specication: The ROTAMAT® Storm Screen RoK 1 is an automatically cleaned screen for stormwater and combined water treatment and is horizontally installed directly behind the overflow sill at overfall weir level. A screw is mounted on a half cylinder of perforated plate (standard perforation: 6 mm). Wear-resistant brushes on the screw flights clean the perforated plate. The screen is driven by a submersible, ex-protected IP 68 motor. During wet weather events, the flow streams through...

➤ Combined and stormwater treatment ➤ ➤ WASTE WATER Solutions ROTAMAT® Storm Screen RoK 2 installed in front of the overow sill Product specication: Also the ROTAMAT® Storm Screen RoK 2 is an automatically cleaned screen for stormwater and combined water treatment but is installed directly in front of the overflow sill. Again, a screw is mounted on a half cylinder of perforated plate (standard perforation: 6 mm). Wearresistant brushes on the screw flights clean the perforated plate. The screen is driven by a submersible, ex-protected IP 68 motor. During wet weather events, the flow streams...

➤ Combined and stormwater treatment ➤ ➤ HUBER Stormwater Bar Screen HSW installed on the sill of the structure Product specication: The HSW Screen is a horizontal bar screen for combined and stormwater screening directly on the sill of the structure. The screen consists of a sturdy, closed square profile frame designed to resist the water pressure, with openings to suit the bar rack elements. These are prestressed to maintain the bar spacing of 4 mm and consist of rolled flat steel and are of a hydraulically favourable design. In order to prevent complete blinding of the bar rack in the...

➤ Combined and stormwater treatment ➤ ➤ WASTE WATER Solutions Outdoor installation of a ROTAMAT® Pumping Stations Screen RoK 4 Product specication: The compact vertical ROTAMAT® Pumping Stations Screen RoK 4 is an automatically cleaned screen that combines screening, transport and compaction in a single unit. The screen consists of a vertical screen basket and a shafted auger in a vertical tube. The wastewater flows through an inflow chamber and then through the perforated plate screen basket which removes the screenings fully automatically. Within the vertically installed screen basket the...

➤ Cleaning system for storage tanks ➤ ➤ in combined and stormwater treatment HUBER Tipping Buckets SK for ecient stormwater storage tank cleaning Product specication: HUBER Tipping Buckets are a sturdy, reliabe system for cost-efficient cleaning of stormwater storage tanks. Whilst wastewater is intermediately stored in a tank, the coarse material contained settles on the bottom of the tank. To remove the settled material, especially in rectangular storage tanks, tipping buckets are used which consist of a trough that takes up the flush water. The trough is supported outside the axis of...

➤ Cleaning system for sewers and ➤ ➤ sewers with storage capacity and overow WASTE WATER Solutions HUBER Power Flush® – Sewer ushing System for sewer systems and sewers with storage capacity and overow Product specication: Cleaning of sewers and stormwater retention sewers has been gaining in importance recently. The main reasons for the ever increasing sedimentation at the bottom of sewer systems and stormwater retention sewers are an insufficient sewer base slope, regular retention combined with slow flushes and a low flow velocity. As a result, the sediments will harden over the course...

➤ System solutions for combined and ➤ ➤ stormwater treatment Stormwater screening combined with overow measurement Product specication: In the event of heavy rainfalls large amounts of combined water may pass into the receiving water course via overflow discharge structures or stormwater overflow tanks. Frequently, there is no screening plant installed with the consequence that the discharged water contains floating and coarse material. In addition, the discharged overflow is frequently not measured and with the omission of measuring equipment will mean a significant loss of critical...

➤ System solutions for combined and ➤ ➤ stormwater treatment WASTE WATER Solutions Stormwater screening combined with activation of unused sewer-storage capacity: HUBER Storm Water Bar Screen HSW Product specication: Stormwater overows within combined sewer systems typically have a xed weir. When the critical rainfall intensity is exceeded they overow at a dened water level height and discharge into a receiving watercourse. Fixed weirs, however, have the disadvantage in that the water is already being discharged before the maximum permissible water level is reached with the consequence that...
