In order to reduce the content of nitrogen in treated wastewater, microbial processes conducting nitrification of nitrogenous compounds and denitrification to gaseous nitrogen are included in the sewage wastewater treatment process. A set of compounds has been found inhibitory to these microorganisms. A procedure is presented for identification of nitrification inhibitors in wastewaters. This includes fractionation of the wastewater sample and location of the inhibitory effect using a nitrification inhibition assay where pure cultures of Nitrobacter are used. A series of unsaturated fatty acids and two monoterpenes were found to constitute the inhibitory effect in a wastewater sample from a plant for drying wood-derived fuel.
