The processing, treatment and purification of water plays an important role in all kinds of different areas of our life: in the treatment of drinking water for private households, the treatment of non-potable and process water in industry, the treatment and purification of water in circulatory processes such as in swimming pools or in many production processes in industry, and also in the treatment and purification of waste water.
The topic of “Waste water" is dealt with in grades 7 to 10. The physical, chemical and biological processes carried out in sewage plants offer a multitude of starting points for interdisciplinary teaching of scientific subjects. The interdisciplinary aspect “Environment" can also be dealt with optimally in this connection.
The media files (charts, interactive graphics, graphics, photos, information sheets, a video, a worksheet, a link list, an experimentation instruction and several guidelines for teachers) will support practical, real-world-oriented teaching on this topic.
