“…The plants process achieved almost complete ammonia removal during the wastewater treatment processes in three different plants, process in the ITP does not remove ammonia may be because of the toxicity of high oxygen concentration to the nitrifying microorganisms (Uemoto et al, 2000). Similar to the Fargo WWTF results, ammonia inall the samples were totally nitrified during the incubation (Pehlivanoglu-Mantas and Sedlak, 2008; Simsek et al, 2012, Liu, et al, 2013.…”

This research aimed to assess the composition of total dissolved nitrogen (TDN) species, particularly dissolved organic nitrogen (DON), over the traditional wastewater treatment operations in three biological nutrient removal (BNR) wastewater treatment plants (WWTPs) in Jordan. It had been found that the DON percentage was up to 30% of TDN within the effluent plant;which restricted the plant's ability to eliminate nitrogen to minimal amounts. Effluent DON levels from the three plants varied from 11.7 to 34.8 mg N/L and would not fluctuate substantially, even if there seemed to be a substantial difference inside influent organic nitrogen levels. The main transforming of DON and biodegradable dissolved organic nitrogen (BDON( along the treatment train had been noticed in the aerobic method. More than 70% of effluent DON was consisting of hydrophilic materials, which promote algal growth. The research presented significant information for foreseeable future improving of WWTPs or the choice of DON elimination techniques to satisfy additional challenging nitrogen release limits.Keywords: total dissoloved nitrogen, dissolved organic nitrogen (DON), bioavailable/biodegradable dissolved organic nitrogen, wastewater treatment plants, Jordan.

“…Parkin and McCarty (1981) reported that about 70% of the total influent DON can be removed in suspended growth systems of WWTFs. Simsek et al (2012) reported that 62% of the influent DON was removed by a trickling filter (TF) treatment process. The effluent DON was 50% and 51% biodegradable (ammonifiable) for activated sludge (AS) and TF WWTFs, respectively (Murthy et al, 2006;Simsek et al, 2012).…”

The effluent DON was 50% and 51% biodegradable (ammonifiable) for activated sludge (AS) and TF WWTFs, respectively (Murthy et al, 2006;Simsek et al, 2012). Traditionally effluent DON was believed to be fully nonbiodegradable and hence would not be available as a nutrient source in receiving waters.…”
