“…The study treating duck house wastewater reported 99% removal, the landfill leachate, the dairy wastewater study reported 98% removal, and the complex chemical wastewater reported 93% [ 24 ]. The Brewery wastewater reported an 80% reduction in BOD 5, lower than the efficiency found in this study [ 25 ]. Fig.…”

“…High organic loading conditions limit the nitrification process since oxygen was used to consume organic matter. Nitrification and denitrification are primarily controlled through DO concentration and an alternative cycle of aerobic and anoxic conditions in the reactor [ 25 ]. It is clear from Fig.…”

“…The Tapioca wastewater treatment using SBR has shown a 60% nitrogen reduction in the effluent. Since nitrification was observed, the SBT was well aerated due to the absence of denitrification, indicating anaerobic conditions did not exist in the SBR setup [ 25 ]. Tube-settler also demonstrated similar results in Fig.…”
Hospital wastewater treatment is gaining attention in recent studies due to its complex nature. The performance of the sequencing batch reactor coupled with tube-settler was investigated for hospital wastewater treatment. The performance was evaluated regarding removing organic matter and nutrients (nitrate and phosphate). The phosphate was removed in the sequencing batch reactor and its associated tube-settler with a 60% removal efficiency margin. Nitrification was observed in sequencing batch reactor and tube-settler, but denitrification could not be achieved. The nitrification–denitrification process was not completed during the process. The current work’s main aim was to understand and optimise the operational parameters involved in the performance of the sequencing batch reactor. The operational parameters were optimised using Design expert software, and Response Surface Methodology involved a four-factor and five-level central composite design. The percentage removal of chemical oxygen demand, nitrate, and phosphate was selected to be observed during this study.

“…16sRNA results indicated elevated levels of Comamonadaceae. Truong, Nguyen, Nguyen, and Bui (2018) noted that the size and settleability of aerobic granular sludge increased with increasing OLR from 2.5 to 7.5 kgCOD/m 3 /day when treating tapioca wastewater in a sequencing batch reactor. The authors reported that the granule size was about 2.5 mm, and the SVI was lower than 50 ml/g, with COD and ammonia-nitrogen removal efficiencies over nearly 90% or more.…”
Literature published in 2018 and literature published in 2019 related to food-processing wastes treatment for industrial applications are reviewed. This review is a subsection of the Treatment Systems section of the annual Water Environment Federation literature review and covers the following food-processing industries and applications: general, meat and poultry, fruits and vegetables, dairy and beverage, and miscellaneous treatment of food wastes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
