TL;DR: In this paper, the authors presented the results of research about the possibility of using trickling filter for high ammonia concentration sewage treatment and used reject water generated during anaerobic sewage sludge stabilization in dairy wastewater treatment plant (WWTP).
Abstract: The article presents the results of research about the possibility of using trickling filter for high ammonia concentration sewage treatment. The study was conducted with the use of reject water generated during anaerobic sewage sludge stabilization in dairy wastewater treatment plant (WWTP. They are usually returned to the beginning of WWTP. The value of BOD in reject water was approximately the same as in domestic and municipal sewage. Ammonia nitrogen concentration was varied from 145,0 to 390,0 mgN-NH4 +/l and phosphorus from 16.0 to 38.0 mgP/l. The study used the Gunt test system CE701e, which allows controlling basic parameters of the treatment with trickling filter. Significant reduction of organic matter, total nitrogen and ammonium was observed during treatment. Average removal efficiency of ammonia nitrogen ranged from 73.6 to 80.3%. In the case of the Kjeldahl nitrogen removal efficiencies ranged from 74.4 to 79.8%. Because of the aerobic conditions during the treatment of phosphorus removal efficiency was low and varied from 32.0 to 33.7%. The research confirmed the efficiency of trickling filter for treatment sewage with high concentration of ammonia nitrogen.

TL;DR: In this paper, the rotating biological contactor (RBC) process was used to increase the rate of nitrification and decrease the required RBC surface area for secondary treatment or nitrification, resulting in less costly upgrades for existing trickling filter wastewater treatment facilities.
Abstract: : Typical Army wastewater treatment plants can be upgraded to secondary stadards for BOD5 by incorporation of the rotating biological contactor (RBC) process downstream of existing trickling filters. Existing trickling filter plants can also be upgraded for ammonia removal by using the RBC process for nitrification. In these studies both BOD5 removal and nitrification rates were affected by wastewater temperature. However, nitrification rates were more sensiive to low w astewater temperature than secondary treatment. Results indicate that chemical feed for elevated pH levels of about pH8.0 in the RBC influent increases the rate of nitrification and decreases RBC surface area requirements. The decrease in required RBC surface area for secondary treatment or nitrification will result in less costly upgrades for existing trickling filter wastewater treatment facilities. Increased rates of nitrification will also result in more consistent and reliable attainment of effluent standards. The RBC in this study received effluent from a high-rate trickling filter that performed at less than secondary effluent standards. Performance of the RBC was evaluated over a 2-year period without temperature control, in order to determine both summer and winter efficienc eis for BOD5 reduction and ammonia-nitrogen removal.
