TL;DR: A large pilot-scale NTF was operated under conditions that simulated the raw water quality of poorly protected catchments typically found in SE Asia, with the objective of reducing the ammonia driven chlorine demand during disinfection.

TL;DR: In this paper, the effect of liquid-phase mass transport on BOD removal efficiency in a trickling filter is presented based on an analytical model of the process, and the applicability of the results presented to the analysis of experimental data and trickling filtering design is discussed.

TL;DR: In this paper, an ultra-low energy consumption continuous flow (UECF) process was used for enhanced nitrogen removal from rural sewage, where the ammonia in sewage was first oxidized to nitrite in a bio trickling filter (BTFPN) supplemented with natural oxygen.

TL;DR: A new biological nitrification–denitrification system was constructed with a trickling filter for nitrification, suitable in tropical and subtropical areas with annual minimum temperatures of over 15°C and the DN removal efficiencies did not reach theoretical values for all conditions tested.
Abstract: In the modified Ludzack–Ettinger process, high-energy input is required in a nitrification tank. To address this issue, a new biological nitrification–denitrification system was constructed with a trickling filter for nitrification. The effects of recirculation rate of nitrified liquor and temperature through the treatment of municipal wastewater were evaluated. The highest DN removal efficiency was observed at 6.5 h of hydraulic retention in the denitrification tank and 350% of recirculation rate of nitrified liquid against the influent flow rate. The DN removal efficiencies did not reach theoretical values for all conditions tested because the COD/N ratios in the influent often decreased to less than 5 g-COD/g-N and temperatures dropped to less than 15°C in winter. The former inhibited the denitrification process and the latter significantly decreased the bioactivity of nitrifying bacteria. As such, this system is suitable in tropical and subtropical areas with annual minimum temperatures of over 15°C.
