Trickling filter nitrification
WebThe combined trickling filter and activated sludge processes differ primarily in two respects: the relative sizes of the trickling filter and aeration basin, and the RAS recycle location. Table 1 summarizes the combined processes, along with the parent activated sludge (AS) and trickling filter (TF) processes. WebNitrification and denitrification are two suggested processes that significantly reduce nitrogen levels in wastewater. This fact sheet will primarily focus on the nitrification process using a trickling filter system. TFs are designed as aerobic attached growth reactors and have been proven to be suitable for the removal of ammonia nitrogen.
