Who has invented it?
The history of the electro-osmosis-method is more than 200 years old. In 1806 Prof. Ferdinand Friedrich von Reuss observed a movement of water molecules from plus to minus in porouse soil with applied direct voltage when doing tests with mud. From around 1900 up to the 1930s turf, brown coal and grain were dried with this method and from 1935 on moistured walls. Paul Ernst developed the first system for walldrying and received the swiss patent for it. For more than 20 years now WiTRO`s system is on the market.
