English Summary

This report surveys alternative water treatment, and different kinds of alternative water treatment devices, e.g. vortexers, indirect water treatment and magnetic water treatment. Reported physical, chemical, biological and more general ecological effects on treated drinking water and on plants watered with treated water is discussed extensively.

This includes effects on water appearance, turbidity, dissolved gases, washing effect, concrete strength, lime scale and effect on crystallisation processes in general, effects on absorption and on some redox related ions. There are extensive reports on effects on growth, resistance and durability of vegetables and fruit (and flowers) from commercial farmers. Other reported effects include decrease of bacterial count and algae and decreased chlorine dosage needs. There are also some more ecological effects, such as en effect on ponds, liquid manure and compost.
