Biological nutrient removal from slaughterhouse wastewater via nitritation/denitritation using granular sludge: an onsite pilot demonstration

Abstract: BACKGROUND: In this study, an onsite pilot sequencing batch reactor (SBR) of 450 L was operated at a local Flemish slaughterhouse in two consecutive periods. During period I, nitrogen removal via nitritation/denitritation (Nit/DNit) was achieved by the use of an innovative startup strategy without seed sludge and subsequently maintained by the use of aeration phase length control based on the oxygen uptake rate (OUR). In period II, the operational strategy was modified. In order to obtain Nit/DNit granular slu… Show more

“…Palomares-Rodríguez et al (2017) provided economic and energy demand justification for leveraging a combination of aerobic and anaerobic treatment that would reduce energy requirement by 76% and environmental impact by 30% [54]. Sequencing batch reactors have also been studied to remove COD and nitrogen to operate between nitrification and denitrification, aerobic and anaerobic methods [74,75].…”

“…For biological processes, combined aerobic and anaerobic processes show the most promis for treatment of SWW. These combined treatments are effective at removing SWW pollutants over a wider range of organic loading rates and hydraulic residence times due to the aerobic/anaerobic conditions [72,74,125]. If combined aerobic and anaerobic processes are followed by disinfection, the effluent can meet water quality standards for BOD, COD, nutrients, and pathogens [73].…”

“…In this study, the volume exchange rate was only 9%. The sludge settling selection pressure was 0.13 m/h during the whole study making the selection of slow-growing carbon-storing microorganisms the main selection criterion for AGS formation (de Kreuk & van Loosdrecht 2004;Stes et al 2019;Dobbeleers et al 2020).…”

“…The genera Tetrasphaera and Dechloromonas were identified, while Accumulibacter species were much less abundant. Recent work reported the presence of other genera in AGS reactors treating more complex wastewater (Dobbeleers et al, 2020;Layer et al, 2019;Stes et al, 2018). In contrast to Accumulibacter that only uses VFAs as primary substrate (Marques et al, 2017), Tetrasphaera seems to have a more versatile physiology which results in the assimilation of different organic substances (e.g.…”

“…Industrial (complex polymeric) wastewater of food-and meat processing companies contains a mixture of organic substances, like proteins and carbohydrates (Dobbeleers et al, 2020;Stes et al, 2018). Knowledge acquired on AGS treating simple wastewater cannot be easily transferred to AGS treating more complex wastewater (Layer et al, 2019).…”
