Ammonia wastes discharge into water body will have a negative impact
and cause ecological and healthy problems. High concentration of
ammonium will give eutrofication problem in water body therefore dissolve
oxygen demand will be decreased as well as self purification of water
ecosystem. This negative impact will influenced for aquatic organism
which died gradually. The efforts decrease of ammonia concentration is
by biological waste water treatment utilizing microbes for changing
ammonia to nitrite and nitrate. One of the technologies could be carried
out is nitrification process technology using biofilter with 80% efficiency.
For decreasing ammonia concentration can be used biological treatment
by using microbe which can change it ti nitrite and nitrate
