In surface water treatment, salt is not a problem. Instead there are many suspended particles, like mud and sand that need to be filtered. In addition to that, many microorganisms and other organic materials that can be damaging for humans need to be removed before the water can be used for human consumption. A technique called 'deep bed filtration' | In surface water treatment, salt is not a problem. Instead there are many suspended particles, like mud and sand that need to be filtered.

- | Paul touched upon the geopolitical intricacies of water treatment, illustrating it with an example of the Danube water basin, which covers several nation states – from Germany, Austria, Hungary, Serbia, Bulgaria, etc. The water polluted closer to the source (say in Germany) will effect the water and its treatment down-stream. The Danube River Basin Management, which should comprise all countries on the Danube (and beyond – as the basin also includes several networks of groundwater) is in the making. We discussed that not just industrial pollutants, but also our own waste is extremely dangerous for the flora and fauna of the basin. An example was given of the concentration of the chemicals from contraception pills that make whole populations of fish infertile. Anti depressants and hard drugs such as cocaine were other big problems that were mentioned. | + | Paul touched upon the geopolitical intricacies of water treatment, illustrating it with an example of the Danube water basin, which covers several nation states – from Germany, Austria, Hungary, Serbia, Bulgaria, Romania, etc. The water polluted closer to the source (say in Germany) will effect the water and its treatment down-stream.

We concluded with a short discussion about the taste of water and the need for water tasting, not just in fancy restaurants, | We concluded with a short discussion about the taste of water and the need for water tasting, not just in fancy restaurants, |
