“…The (a) and (b) values were calculated as 0.503 and 0.9919 respectively with the correlation coefficient (R 2 =0.991). In a literature study, these values a and b were found to be 0.197 and 1.42 respectively during the treatment of textile dyeing wastewater in the UASB reactor (Gnanapragasam et al, 2017). These values for UASB reactors is so close each other.…”

<p>Microbial kinetics of a hybrid upflow anaerobic sludge blanket (UASB) reactor were investigated when treating chemical synthesis–based pharmaceutical wastewater. Monod, Grau first-order, Grau second-order, Stover-Kincannon, Chen & Hashimoto kinetic models were applied to the hybrid reactor. The second-order model was found to be the most appropriate model for the hybrid reactor (R2 = 0.99) and offers the best description of the process. The substrate removal rate constant (k2S) was found to be 4.91 d-1.</p>

“…The anaerobic process has an economic advantage in which the sludge produced is low so it does not need to pay for the handling of sludge caused by anaerobic reactors which is an immediate economic benefit [8,[12][13][14][15]. Anaerobic biomass fermentation accompanied by methane production needs a long time, so organic waste requires a proper anaerobic digester [16,17]. Processing of the anaerobic system is divided into a suspension system, attached and a combination of them.…”

“…Kinetic model is an analytical approach to describe specific parameters for monitoring system performance. Kinetic models are currently being developed to help design and optimize processes for upflow and hybrid anaerobic reactors [1,17,21,29,30]. The kinetic model is also considered feasible and suitable for approaches on removal performance, prediction of effluent concentrations and optimization of biological processes [31].…”

This research aims to examine the varians of organic loading rate (OLR) on degradation of tofu wastewater using the hybrid upflow anaerobic sludge blanket (hybrid UASB) reactor using the modified kinetic model of Stover Kincannon. This reactor was operated at OLRs variation of 1.5-12 kg COD m -3 d -1 and HRT of 12 -24 hours for 328 days. Higher COD removal efficiency of 86.41% and biogas production of 7700 mL were achieved at OLR 4.8 kg COD m -3 d -1 and HRT 24 hours on 140 days. Modified Stover-Kincannon model was observed and matched data sets were obtained. The kinetic values of model obtained at HRT variations, the parameters KB and μmax were 3.7, 12.97, 2.42 mgL -1 d -1 and 0.59, 9.41, 0.014 mgL -1 d -1 , respectively. This model was a plot of the inverse of the removal rate, versus inverse of the total loading rate resulted in a straight line. It showed that the Stover-Kincannon Model is the rate of substrate removal was affected by the organic load rate (OLR) that flowed into the hybrid UASB reactor.

“…Therefore, kinetic parameters are an important basis in biological waste treatment. Tofu wastewater treatment is carried out on various kinds of bioreactors used and the expected goals, depending on the variables and parameters used (Gnanapragasam et al, 2017;Lay et al, 2013;Mansouri, 2014;Narra et al, 2014) researched tofu wastewater using a CSTR reactor with efficiency analysis of the conversion of tofu wastewater into hydrogen and ethanol for energy sources in a tofu industry factory evaluated by several types of mud variations with HRT variations of 6-24 hours (Sitorus et al, 2010) investigated the treatment of tofu wastewater for COD, TSS, and Turbidity efficiency using the UASB (3L) reactor with the coagulationflocculation process. Characteristics pH 3.2, COD 14.744 mg/L, TSS 618 mg/L, turbidity 876 NTU.…”

“…Based on the biochemistry and microbiology of biological processes, kinetic studies provide a rational basis for process analysis, control, and design. A kinetic model is currently being developed to assist in the design and optimization of processes in reactors (Abyar et al, 2017;Gnanapragasam et al, 2017;Jafarzadeh et al, 2009;Mansouri, 2014;Narra et al, 2014). The kinetic model is also considered feasible and suitable for approaches to removal performance, prediction of effluent concentration, and optimization of biological processes (Cho et al, 2020;Mansouri, 2014;Rodziewicz et al, 2019;Wu et al, 2016).…”

It is necessary to design a nitrification bioreactor process so that further processing takes place optimally. Performance studies are carried out by evaluating the kinetic parameters that apply specifically to the applied process. The Monod model was applied to determine the value of kinetic parameters in designing and operating a bioreactor. This study aims to determine the value of the kinetic parameters to variations in feed concentration (50, 75, and 100%). The mechanism of the reactor process for the decomposition of pollutants, the influent is fed into the reactor with an up-flow pristaltic pump. The decomposition process provides contact time between organic matter and microorganisms, resulting in a good separation from the reactor outlet. The most optimum kinetic parameter value at 100% wastewater concentration with a value of (k) 1.1086 (dayˉ 1), (Ks) 1.0564 g l-1, (Y) 5.4862 mg MLVSS/mg, (kd) 1.7944 (dayˉ 1), (µm) 6.8372 (dayˉ 1).
