A new idea for your training - Modular Wastewater Training System

Comprehensible instruction for technical processes

Kläranlage Fachkraft für Abwassertechnik Ausbildungshilfe

In order to make technical processes and stations at a wastewater treatment plant understandable in the truest sense of the word, Achim Höcherl, the head of the wastewater treatment plants in Bonn, developed these magnetic cards for his in-house lessons. We were so enthusiastic about the idea and its success that we designed the so-called DWA Modular Wastewater Training System in 2010. Until now, the Modular Wastewater Training System has proven itself internationally in more than 10 languages. Meanwhile, the system is part of national and international skills competitions in the field of water technology.

All the important stages of wastewater treatment are vividly depicted on 63 magnetic picture cards. On a flipchart or whiteboard you can quickly and easily “reconstruct“ the complex processes, test your knowledge or organize group work.

Your training system includes

63 Magnetic picture cards

63 Magnetic picture cards for presentation on whiteboard. The label has space to add the heading term in your language.

1 Workbook “Fit in Wastewater Technology?"

1 Workbook “Fit in Wastewater Technology?” with exercises and case studies that can be solved with the picture cards, furthermore field work and reflection tasks. As a conclusion, you can test yourself against the examination tasks from vocational competitions of the past years.

2 Flashcard sets

2 Flashcard sets with 63 picture cards for various purposes such as group work learning, discussion of scenarios, documentation of your learners notes or a competing exercise with your colleagues or friends.

5 Whiteboard markers

5 Whiteboard markers enable you to draw material flows in your process diagram.

Permanent marker

Permanent marker to label the cards in your language.

Transport case
