Figures and facts about water
• 900 million people lack access to drinking water
• 90% of all diarrhoeal diseases could be avoided by proper water purification
• According to a UN Resolution of 2010, every person has a right to clean water
• By 2030 47% of the world’s population will live in regions with a lack of drinking water
• Water and wastewater plants are high energy consumers and responsible for up to 30% of municipal power consumption
• 80% of communal wastewater enters rivers, lakes and seas untreated

Nowadays training is not sufficient to cover the huge demand for skilled staff in a world of technological change. The trainings available are usually too theoretical. Holistic and practice-oriented training solutions are needed to train staff efficiently. Analytical and problem-solving skills are most important to reduce waste and increase efficiency of a plant. Understanding the steps before and after a specific process helps to “think ahead” and reduce down times. Automation does not mean “replacement of human resources”, it helps to standardize key processes and produce clean safe water.

The EDS — Environmental Discovery System for Water Management
The EDS for Water Management
simulates the core processes of water and
wastewater treatment.
It shows how water and wastewater are
collected, transported and treated. It
fosters practical learning.

The advantages of the EDS for Water Management
The equipment
• is highly flexible
• has been designed according to industrial standards
• simulates the core processes of water and wastewater treatment plants
• familiarizes trainees with process automation and closed-loop control technology
• fosters practical exercises and experiments
• corresponds to its “real” counterparts in function and design

Module 1:
Water purification
Module 2:
Water supply
The outcomes of the six learning modules (1/3)
The trainee is able to • handle the basic processes of precipitation, flocculation and sedimentation • deal with chlorine dosage and measurement of free chlorine concentration • name problems with too high or too low chlorine dosage
The trainee is able to • name the characteristics of different pump types and operate the pumps • understand the influences on pump performance during water supply • work with the relationship between pressure and volume flow rate in a piping system • control water supply by different valve types • control the fill level of a high tower while simultaneously water is withdrawn • describe the significance of pressure zones in a water distribution area • identify water loss and name the basic problems involved in detecting leaks
in water distribution networks
DC-B/Christian Wehlers EDS for Water Management 5. April 2013
The trainee is able to • simulate and explain basic processes related to the sedimentation of sludge • analyse the behaviour of flocs under different flow rates and solids load • name the consequences of hydraulic overload of a wastewater treatment
plant • describe the basic function of aerobic water purification and the role of
sludge recirculation • describe the significance of oxygen injection into the activation tank • measure the amount of dissolved oxygen and explain the benefits of
constant measuring
Module 3:
Wastewater transport
Module 4:
Wastewater treatment
The outcomes of the six learning modules (2/3)
The trainee is able to • handle the transport of solids in sewers with varying flow rates in a combined
sewage sewer • name the effects of exceeding the hydraulic capacity • deal with the sedimentation and the impact of a blockage in a sewer • name the basic mechanisms that lead to a first flush • describe the role of a rain overflow basin and his components • line out the basic mode of operation of a through-flow basin with regard to
retention of solids
DC-B/Christian Wehlers EDS for Water Management 5. April 2013
The trainee is able to • identify the difference in energy consumption between the free and the
narrowed piping system • find out potentials for energy saving and energy conversion in water- and
wastewater treatment processes • measure energy consumption and calculate efficiency of pumps and valves • compare different control strategies regarding their energy demand to
optimise efficiency • estimate and calculate costs of different controller strategies • describe the structure and methods of energy management
Module 5:
Monitoring, controlling and optimising
Module 6: Energy optimisation in water
and wastewater treatment plants
The outcomes of the six learning modules (3/3)
The trainee is able to • differentiate between linear and non linear system characteristics • control the fill level using a two-step controller and a continuous controller • control the flow using a proportional-integral controller • describe the characteristics of different controllers and their relevant settings • explore the impacts of controller settings on energy consumption • adjust the volumetric flow by using different controller settings for the
proportional media valve • evaluate the best control strategy for the aeration process
