The development of a deammonification treatment to remove nitrogen from recirculated water used in aquaculture (DeammRecirc)
Start date: Jan 1, 2011, End date: Apr 30, 2013,
The aquaculture industry has been very slow to adopt denitrification methods. Present practice is to convert the toxic metabolic waste product ammonia via nitrite to nitrate in a nitrifying bio-filter. This microbial process demands oxygen and reduces the pH, requiring expensive buffering treatment. The accumulating nitrate is generally flushed from the farm into recipient waters without pollutant ...
