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

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)
