Our sludge water treatment plants consist of up to 3 barriers.
They therefore meet all the criteria currently discussed in expert circles. The recommended standard here is 2 barriers plus a downstream device to avoid secondary contamination.
First barrier
The sludge water is removed from the storage tank using a surface extraction device.
Coarse impurities and a large part of the cloudy substances are held back in the automatically flushable sand/active carbon filter.
Second barrier
The second stage of sludge water treatment is ultrafiltration. This produces a filtrate free of solid substances. Bacteria are reliably filtered out (for instance, cryptosporidia range in size from 5-10 my, E-coli bacteria are
1.5-3 my in size).
Viruses are smaller than bacteria. However, viruses require a host to survive, i.e. they embed themselves in the impurities, so they are filtered out along with them in ultrafiltration.
Third barrier
In the third stage, the reverse osmosis plant, more than 90% of the salts are removed.
Additional chlorination is an extra option after this, and if necessary re-hardening is also possible.
The water is re-introduced to the surge water container. The 4th barrier is the pool water treatment.
