Wastewater transport station: Water becomes wastewater

Wastewater transport station: Water becomes wastewater

New 

Function
The “wastewater transport” station teaches control technology for wastewater disposal and the associated processes. It comprises four sub-areas:

  • Feeding device for supplying a soiled load
  • Sewage pipe section with branch
  • Tank with overflow rim as a rain retention and sedimentation basin
  • Tank as a primary settlement tank for the biological stage and the option of starting sludge removal via a pneumatically automated fitting.

Plastic granules are used as the soiled load and can be air-dried and re-used after utilization. Flooding due to rainfall or problems transporting solids can be simulated realistically.

The fluids are supplied to the primary settlement tank via a pump. A flow meter records the flow rate, which is configured via a motor control system of the pump or a proportional media valve.

The media valve functions based on the principle of a pneumatically activated constriction-hose valve. The throttle opening can be configured via air pressure with a proportional pressure regulator valve.That allows the effects on energy efficiency and the flow control quality to be shown clearly.

 

The station is fully assembled, wired and tested.

Including control system with FluidLab®-EDS® Water Management, EasyPort, connecting cables, 1x accessory set with sedimentation granules and "Getting Started" technical documentation.

Main components
3 l tank, including overflow rim, 1 l tank, gravity duct, capacitive proximity sensor, float switch, magnetic-inductive flow sensor, ultrasound sensor, centrifugal pump, proportional media valve, proportional pressure regulator valve, pneumatic slide, metering screw for metering solids, electric connection board, aluminum profile plate.

Note
For single operation, a water supply tank/ground water (order no. 8024503) is required.
