Further addition of 3 mL and 5 mL EM
reduced the phosphorus removal efficiency of the mixed EM-MA
system. However, the ammonia concentration increased after 7
days of EM bioremediation mode to the concentration of 7.0mg L1.
Increase in ammonia concentration was not apparent in MA phytoremediation
and symbiotic MAeEM bioremediation. Ammonia in
EM bioremediation mode and phosphorus concentration in all
bioremediation modes were found to increase following the
maximum absorption on 6e8 days.
