BIOGEST - Model Type KS -Gate Flushing System for Storm Tanks and Sewers

SHARE
The BIOGEST Gate Flushing System Type KS is engineered to address the challenges faced with sediment build-up in storm tanks and sewers post-storm operations. This system is crucial in mitigating risks like blockages and odors that arise due to sediment accumulation and septicity. Constructed from robust stainless steel options such as AISI 304 and AISI 316Ti, it comprises essential components like a gate, frame, lock, hydraulic cylinder, power pack, and control panel. Operatively, the system uses a float switch to monitor and respond to water levels during storm conditions, ensuring automated closing and flushing sequences. The hydraulic mechanism guarantees precise gate operations, while the system's intelligent control optimizes cleaning efficiency by leveraging water pressure to dislodge and remove debris effectively from surfaces. This integration results in enhanced maintenance, operational efficiency, and hygiene within stormwater management systems.

Storm tanks or sewers require cleaning after operation during storms due to the sediment deposited on the tank or sewer floor once the storm has subsided. If the system is not cleaned the potential for blockages is increased and malodours will occur due to septicity. The BIOGEST® Gate Flushing System Type KS is an ideal solution to the problem.

The flushing gates are manufactured from stainless steel (AISI 304 or AISI 316Ti) in several sizes and consist of the following: The gate, the gate frame, the gate lock, the hydraulic-cylinder, the hydraulic-power pack and the BIOGEST® control panel.

Both the tank and flushing chamber are empty. In dry weather situation the gate hangs loose on the frame and stays open.

During a storm, the level in the storm tank / sewer will rise and the gate will be closed following a signal from the float switch. The hydraulic pump starts and drives the shaft, which in turn closes the gate. As soon as the gate is closed it is locked mechanically the hydraulic pump shuts off. The flushing chamber fills as the level rises within the tank / sewer.

The storm subsides and the storage chamber empties leaving sludge and other sewage related debris on the chamber floor.

Once the tank is empty the flushing sequence starts automatically. The float switch sends a signal to the control panel. The solenoid valve then turns the hydraulic pump on. The drive shaft reverses and release the retaining lock hooks. The gate swings open due to the pressure of the head in the flushing chamber releasing the flush water and cleaning all the solids from the floor of the tank or sewer.

  • Subsequent installation possible
  • Suitable for use in storm tanks or sewers
  • Minimal energy consumption
  • Low Maintenance
  • Flushing with rainwater and sewage water
  • Delayed closing of the flap thanks to special damper function
  • Repeated flushes possible
  • Minimization of hydraulic loss using brake cylinders
