The GRAS consisted of a culture tank, a screen filter and a foam fractionator for removal of particulate and dissolved solids and a trickling filter for conversion of ammonium- and nitrite-nitrogen to relatively harmless nitrate-nitrogen.
The culture of goldfish at a stocking density of 1.08 kg-m3 was continued for a period of two and half months.
Based on mass balance analysis of ammonium- and nitrate-nitrogen and assuming the trickling filter to be a plug f...
