A new idea for your training - Modular Wastewater Training System

Comprehensible instruction for technical processes

Instruction means making technical processes comprehensible. Achim Höcherl, superintendent of the wastewater treatment plants in Bonn-Beuel und Bonn-Duisdorf, developed specially designed magnetic cards for his in-house instruction courses. The individual stations of wastewater treatment are eyecatchingly depicted on the cards and can thus be used unrestrictedly at any time by trainers, trainees or even technical experts on flipchart or whiteboard. We were so enthusiastic about this idea that we now offer the Modular Wastewater Training System in English.


See how it works in practice

The images show how easy it is to learn, discuss depict and test by using the magnetic cards.

See for yourself!

Magnetic cards

66 magnetic cards displaying all important stages of wastewater treatment in a memorable way. Interrelations can be illustrated on whiteboard or flip chart by using the magnetic cards.

Flash cards

63 flash cards "for your pocket" (in size of a playing card) showing the most important stages of wastewater treatment plants according to the magnetic cards. Indicated on the back of the cards is concise additional information for the learner such as are reference values or calculation formula.

Questions on USB-stick

About 130 questions on wastewater engineering are included on USB-stick. The questions are stored in ppt-format and thus can easily be expanded.
