The Ammonia Nitrogen Removal Enhanced by Biological Aerobic Filter Packed with a Novel Lightweight Zeolite Particles

Abstract:

The ammonia nitrogen (NH₄-N) removal enhanced by biological aerobic filter (BAF) packed with novel micro-mesoporous lightweight zeolite particles (LZP) as carrier. The results showed that the biofilm can quickly grow up using LZP as media in the BAF. HLR of 1.2 was chosen as the optimal value under the average influent NH₄⁺-N concentration of 24.6 mg/L, percent NH₄-N removal of 87% and NLR of 0.24 kgN/m³.d was achieved. The kinetic performance of the LZP-BAF indicated that the relationship of NH₄-N removal efficiency with the L could be described by an exponential equation (C_e/C_i=exp (-1.24/L^0.344)).
