Yellow water treatment Content
• Resource recovery
» steam stripping
» evaporation
• Elimination of micropollutants(here pharmaceutical residues - PhaR)

Yellow water treatment Resource recovery
steam stripping (N-recovery)
• plant for ~ 5,000 pe
• N - BalanceNH3
in ~ 3,5 g/lNH3
out ~ 0,1 g/lNH3
cond 80 - 120 g/l
• ammonia water 25 - 35 l/m3 YW
• no precipitation within processTP YWin ≈ TP YWout
Steam stripping plant for production of ammonia water
F. Tettenborn, J. Behrendt, R. Otterpohl
Yellow water treatment Volume reduction - concentration
Evaporation• plant for ~ 80 pe• concentration rates
more than 40x of initial conc.• recovery rate N,P > 90 %• no precipitation within process• pretreatment necessary (pH)
Vacuum evaporation
