The Advanced digestion system, treating 50% of the WAS sludge load, will operate totally independent from the conventional digestion plant (based on the other 4 digesters) which is treating the other 50% of the sludge load. In the future an additional, identical B6-4 line can be added to transform the remaining conventional digesters into a second advanced digestion line
