water level control
swinging jet pump
bring movement into the pool. Their strength lies in pools with “difficult” geometry such as blind spots or unfavorable bottom inclinations. swinging jet pump from bgu are horizontally movable and achieve an optimum overall cleaning result with the help of the freely programmable bgu-MoRIS control unit.
‘ Cost-effective cleaning, as fewer jet cleaners are required
‘ cleaning individually controllable for basins
‘ Wall mounting possible, thus reducing deposits
‘ compact design
‘ Special designs possible (e.g. in the middle of the basin)
swinging mixer
achieve good cleaning results in small to very small tanks with “difficult” geometry. They can be moved horizontally and ensure low operating costs thanks to their low-maintenance design with clog-free propellers. With the help of the freely programmable control unit from bgu, an optimum overall cleaning effect is achieved that is tailored to the pool.
‘ Free positioning, independent of the rinsing sump
‘ Low energy consumption
‘ Suitable for very small basins
‘ Retrofitting in existing basins possible without any problems
‘ Individual adaptation to the respective basin geometry
Surge rinsing drums
clean stormwater tanks and storage sewers with a powerful flushing surge. They relieve the systems as they can be operated with mixed water and without external energy. Surge flushing drums are available in two designs: floating and top-fillable.
‘ Powerful flushing surge thanks to large flushing volume and special discharge geometry
‘ Particularly suitable for low structures
‘ Very economical operation, as flushing with mixed water
‘ Flexible system enables a wide range of installation options
> Can also be used as a flush tilt without a stop, resulting in low dynamic stress and no impact noise
Surge flush valves
clean effectively with mixed water – without the use of external energy – and therefore without any additional load on the sewage treatment plant, stormwater overflow basins and storage sewers. The flexible system enables adaptation to different tank shapes. This means that the possible cleaning performance can be optimized for every application.
‘ Proven design
‘ Particularly large flushing volumes possible
‘ Any number of flushing lanes possible
‘ Flushing possible with partial filling
‘ No “flushing tipper-specific” structural elevations required
water level control
Stowage flaps H(hanging)
operate without external energy and primarily serve to protect water and reduce costs by increasing the reservoir volume without the need for further structural measures. This is achieved by maintaining a constant reservoir level. As long as the set maximum reservoir target is not reached, the flap gates remain closed and thus increase the reservoir volume. As a result, discharges occur less frequently and the annual volume of water discharged is reduced.
They also meet the definition of self-regulating spillways in accordance with DWA-A 166.
‘ Optional discharge volume measurement via inclination sensor
‘ Adaptable design; very good for retrofitting
‘ Underflows
‘ Increased storage volume
‘ Precise maintenance of the water level
‘ Integrated backflow protection
‘ Optional: backflow compensation
‘ Improved water protection
‘ With 4-sided seal: closed in rest position, reduces odor emissions and serves as access protection
Stowage flaps S(tehend) G(esteuert)
are water level control and correspond to the definition of self-regulating spillways according to DWA-A 111, DWA-A 166, DWA-M 176 and VDMA 24657. They are overflow flap gates that are arranged on the water side of the sill. The required control impulses for the hydraulic cylinder are provided by corresponding sensors and a control system. With this overall system, a dam target is maintained with high accuracy. If necessary, the target level can be subsequently changed.
‘ Optional discharge volume measurement via inclination sensor
‘ Reservoir volume is increased
‘ Electric or hydraulic drive
‘ With stainless steel cylinder
‘ Positive control via sensor system, so that
different flap control can be selected via program
‘ Improved water protection by increasing the reservoir volume
further products
manual penstock for flow control
limit the discharge from RÜBs or other storage basins through a fixed gap. The set value can be changed and reproduced via a scale. The gate valve can be operated above ground using a spindle extension. The setting scale can be read without having to enter the manhole structure.
‘ Scalable without entering the shaft structure
‘ No additional structure required
‘ Integrated ventilation possible
‘ Complete engineering with
documentation incl. Q/h line
‘ Suitable as a shut-off valve
‘ Easy to retrofit
> Discharge gap calculation based on in-house measurements
floating regulator
are suitable for surface water extraction with a constant and continuous flow rate. They can be used for draining large areas and for throttling the discharge at a sewer. They are also suitable for draining retention basins.
‘ 1-90 l/s
‘ For surface water extraction
‘ Continuous, calm discharge
‘ Constant discharge volume independent
of the water level
‘ Light substances are discharged in a targeted manner
‘ Effective retention of floating matter due to
baffle arrangement on float
> Permanent backwater can be realized
Vortex Flow Limiter
can be used for combined and rainwater, depending on the type, and are used for either wet or dry installation. They are suitable for use in stormwater tanks, storage sewers, sewage treatment plants and sewer systems, road and parking lot drainage as well as separator and infiltration systems.
‘ up to 600 l/s
‘ no moving parts – maintenance-free
‘ mainly used for rainwater
‘ low risk of clogging due to free cross-section
‘ use without bottom jump possible
‘ special design: up to 10,000 l/s
‘ quick, easy installation
> no moving parts, only works with hydraulic effects
> progressive characteristic curve
Bed load shafts
have the task of retaining mineral material (gravel, debris, etc.) in sewer systems. This debris sometimes causes considerable wear in sewer pipes and pumps and leads to undesirable deposits and malfunctions in the entire sewer system. Deposited bed load in turn promotes the deposition of organic material with unpleasant odours and an increased risk of accidents for the operating personnel.
Organic material is loosened from the minerals by regularly blowing in compressed air and transported on to the wastewater treatment plant
‘ Reliable retention of bed load in the channel
‘ Adjustable aeration intervals
‘ Best possible separation of bed load and organic matter
‘ Field-proven bed load level measurement
‘ Connection to a remote control system possible
Louvre dampers
protect outlet channels from floating debris and debris on the upstream side. They serve as visual protection and prevent unauthorized entry by people into the discharge channel of stormwater drains.
‘ Optimization of the outlet grid properties
‘ Difficulty of access for rodents
‘ Protection against floating debris and
bed load
‘ Can be flexibly adapted and installed
Stainless steel threaded slider
can be used as reliable, robust and durable shut-off devices in water and wastewater applications under a wide range of operating conditions. They can be installed and retrofitted with little effort.
The extensive use of stainless steel guarantees corrosion resistance even in aggressive wastewater.
‘ Robust, reliable and durable
‘ Seals in both flow directions
‘ Non-rising spindle, therefore also suitable for driving through road caps and similar
‘ Easy installation by dowelling to the building
> Also available with electric drives from common manufacturers
