Water management

Understanding the core processes of the water cycle

Water is an essential part of most areas of human life. This includes water in the form of drinking water or service water, as well as water used to generate electrical power. Water management systems are complex and require vigilant operation, as the applications have far-reaching effects on humans as well as on the environment. Our EDS® for Water Management training systems offer practical exercises and experiments that enable close, detailed analyses of the individual process steps in water management systems, and illustrate how changes in one area can affect the whole system.

EDS® – Environmental Discovery System for Water Management


The EDS® for Water Management is a modular training system which represents the core processes of a water and wastewater treatment plant in the form of a water loop from the source to the wastewater treatment plant and back again.

Thanks to its industry-oriented design, EDS® for Water Management makes it possible to explain the principles behind the collection, extraction, transport, and treatment of water and wastewater. It offers a compact introduction to measurement, open-loop control, and closed-loop control technology.

Winner of the Worlddidac Award 2016, the EDS® Water Management training system is an innovative educational solution that comprehensively prepares learners for the field of water management facility technicians.

Water Purification Station

  • Station is fully assembled, wired and tested
  • Basic water treatment system in the form of a water storage system with an overflow rim
  • A groundwater tank with a submersible pump is required for operation
  • Setting flow rate values for volume control
  • Level measurement via analog pressure measurement
  • Level sensing via capacitive proximity sensors
  • Implementation of a flocculation reaction by adding a flocculant
  • Occurrence of sedimentation
water supply

Water Supply Station

  • Station is fully assembled, wired, and tested
  • Water storage and distribution via an elevated container, e.g., a water tower
  • Elevated container filled via a pump
  • Pump can be operated in open- or closed-loop control mode
  • Water is withdrawn via valves
  • Balancing water quantity provided with the water quantity delivered while dealing with leakage
  • A water supply tank/ground water is required for single operation

Wastewater Transport Station

  • Control technology for wastewater disposal and the associated processes
  • Plastic granules, used as soiled load, can be air-dried and re-used
  • Realistic simulation of flooding due to rainfall and problems transporting solids
  • Flow meter records the flow rate, which is configured via a motor control system of the pump or a proportional media valve
  • Media valve functions based on the principle of a pneumatically activated constriction-hose valve
  • Station is fully assembled, wired, and tested
  • A water supply tank/ground water is required for single operation

Wastewater Treatment Station

  • Maps the physical functions of wastewater treatment after the sludge treatment
  • Contains aeration tank and secondary settlement tank.
  • Plastic granules used as the soiled load can be air-dried and re-used
  • Sludge return has a flow measurement system with an adjustable pump for setting and monitoring the sludge return ratio.
  • Oxygen feeding on the station uses an electrically adjustable compressed air diaphragm pump. Combined with the available oxygen sensor, there is also an option of extending the oxygen feeding system to a control circuit
  • To guarantee energy-optimized oxygen feeding, in-line oxygen measurement is required and must be combined with the oxygen feeding actuator in a control circuit, preventing unnecessary energy use and possible biochemical malfunction.
  • Periodic addition of sodium sulphite (Na2SO3) to the upstream supply water causes continuous oxygen consumption, simulating the oxygen demand of bacteria feeding on organic matter in a real biological treatment of wastewater.

Sand Filtration Station

  • Frequently used filtration processes for separating solids in drinking and sewage technology.
  • Sand layers used for pollutant retention via deep bed filtration
  • Sensors monitor rising water levels until signal shuts off the inlet and starts the backwash process
  • Parameterization of the filtration process is configured on the PC via the enclosed software
  • Transparent filter housing allows monitoring of the cleaning performance of layered quartz sand and quartz gravel
  • The station is fully assembled, wired, and tested
  • Includes water supply tank/ground water

Membrane Filtration Station

  • Drinking water and wastewater treatment in the form of microfiltration and ultrafiltration
  • Retention of pathogenic germs
  • Differences between the cross-flow and dead-end filtration operating modes
  • Backwash processes using previously created system filtrate
  • Pressure resistance test of membrane functionality
  • Station is fully assembled, wired, and tested

Basic Water Circuit System: Fully equipped - Four become one!

  • Includes all necessary water supply and disposal stations: Water Treatment, Water Supply, Wastewater Transport, and Wastewater Treatment
  • Stations also function independently as stand-alone systems
  • Students initially control the ­individual stations in manual override using a simulation box
  • Included EasyPorts are then used to control and observe the ­stations via the control software
  • One PC, to which all four EasyPorts are connected, controls the complete system
  • The basic system stations are fully assembled, wired and tested
  • A water supply tank/ground water is required for single operation
