Many industries need plenty of water for different processes. The water used for these processes compounds of different metals and minerals, meaning that this is not clean water that can be used for drinking.
The scientists from all over the globe are working on potential solutions that could effectively remove various pollutants from industrial water and turn it into a clean water.
The latest interesting research on this topic comes from the VTT Technical Research Centre of Finland, where researchers were able to develop energy-efficient methods for reuse of water in industrial processes, the ones that also allow extraction of metals and valuable minerals.
The current treatment methods of water in purification plants and industrial facilities require enormous amounts of energy. In most cases, water recycling and seawater
desalination processes use filtration membranes that consume plenty of
energy. VTT scientists on the other hand developed intelligent membrane materials, that require significantly less energy, and are based on osmosis technology.
The VTT scientists also developed sensor technology that allows easy and rapid detection of pollutants. They also announced that their technology will be ready for production use within the next few years.
It also has to be said that many researchers are already testing various biological extraction methods by which metals are recovered from mining,
metal and recycling industry waste by using the combination of microbes and chemical
reactions. These new methods and technologies are predicted to appear on the market within the next few years.
We all know that clean water is becoming scarcer with each new day. Cleaning industrial water is certainly something world should aspire to in order to tackle the clean water issue.
