Water treatment tanks are used mainly by aid organisations and the military. To train their operators, szenaris has developed both learning software and a virtual-reality simulation for commissioning the tanks. The learning software also includes a chapter on how to rectify potential problems.

After working through the learning program, users put their knowledge into practice in a virtual environment by starting up the water tank system step by step. In a further virtual reality application, users can interactively select and order replacement parts directly from a 3D model.

Since 2008, vebn has been awarding its seal of quality to selected eLearning solutions developed by its members in order to establish greater transparency for users regarding the quality of individual solutions. Further improvements to the products are also made in the course of the review procedure.

To receive the seal of quality, systems must meet numerous requirements in a total of ninety criteria covering aspects such as technology, content, teaching methodology and cost-benefit ratio.
