Preliminary research on the anammox process and control of nitrogen compounds in a recirculating aquaculture system
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2013, Vol 6, Issue 1
Abstract
Using anammox process in biological filtration of technological water within recirculating aquaculture system is an alternative to nitrification / denitrification process which can reduce production costs, especially energy by replacing aerobic biological processes that require high oxygen consumption, provided through the addition for optimal function of biofilter (conversion of N-NH4 and N-NO2). Aim of this paper is to highlight the first steps in the control of nitrogen compounds in recirculating aquaculture systems using anammox process. Data shown are obtained after 78 researching days (research still ongoing), the results being encouraging, registering an ammonium removal efficiency of 77% in SC1 and of 32% in SC2. Nitrites registered an increase in SC1 and a decrease in SC2 and there are all prerequisites showing that in SC2 anammox activity is more advanced than in SC1. The average of oxygen consumption rate was 0.73 mgL-1in SC1 smaller than 0.99 mgL-1from SC2, which reinforces the idea that there are anammox process in SC2.
