    Hoon:
    Welcome to the forum.
    If you are considering putting the water down the City drain be very careful.
    I looked up your vCard and it appears you work in the plant in Kodiak.
    ISA did this many years ago and killed off the bugs n the sewer plant.
    A lot of problem.
    Even if you let the ammonia dissipate it will still have a high ph.
    Talk to the City first.
    As for going into the ocean-let your conscience be your guide.
    I used to work for ISA in Egigik 30 years ago.

    get or make up a recovery unit and transfer vapour to other parts of system, or into a one tonne cylinder as a liquid. Dumping saturated water down the drain is not good for the enviroment, water saturated with ammonia should be and supposed to be treated as a hazardous substance and subjected a huge draught of legislation laws globally
