“…Several physicochemical and biological technologies have been used to treat swine wastewater, namely, electrocoagulation ( Mores et al, 2016 ), electrochemical ( Huang et al, 2016 , 2018 ) and biological methods such as anaerobic-aerobic ( Aziza et al, 2019 ; Shoukat et al, 2019 ), moving bed biofilm reactor (MBBR; Yang et al, 2015 ), and membrane bioreactor (MBR; Guglielmi and Andreottola, 2011 ; Guadie et al, 2014 ). However, these technologies have limitations such as high initial investment cost, consumption of large quantities of chemicals, requiring large footprint, complex operation and control of parameters, and low nitrogen and phosphorous removal efficiencies.…”

Swine wastewater contains high concentrations of organic compounds, nutrients (nitrogen and phosphorus), heavy metals, and residual antibiotics, amongst others, that have negative impacts on the water environment. The main aim of this work was to remove nutrients from anaerobically digested swine wastewater using an intermittent cycle extended aeration system (ICEAS). The effects of operational parameters such as cycle time, organic loading rate, C/N ratio, and aeration/mixing ratio on the pollutant removal efficiencies of ICEAS were studied and compared with the performance of a conventional sequencing batch reactor (SBR). The following optimal conditions were obtained: cycle time, 6 h; organic loading rate, 0.86 kg COD m −3 day −1 ; C/N ratio, 2.49-2.82; and aeration/ mixing ratio, 1.57. The pH was maintained in the range of 6.0-8.0. The total organic carbon (TOC), total nitrogen (TN), ammonium (NH 4 +), total phosphorus (TP), and color removal efficiencies of ICEAS were higher than those of the conventional SBR, with removal

“…The aromatic amines produced as a result of azo bonds cleavage in the anaerobic step are further degraded in the aerobic one ( Figure 2 ) [ 232 ]. The combined anaerobic–aerobic treatment most often uses mixed bacterial cultures such as activated sludge [ 149 , 204 , 205 , 207 ], anaerobic granular sludge [ 150 , 153 ], anaerobic–aerobic granular sludge [ 142 , 206 ], immobilized activated sludge [ 151 ], or biofilm [ 111 , 153 , 155 ]. The sequencing of anaerobic–anoxic–aerobic conditions is easy to obtain in the sequence batch reactors (SBRs, [ 204 , 205 ])—the decolorization efficiency reached 100% by up to 94% of COD removal.…”

Recent Achievements in Dyes Removal Focused on Advanced Oxidation Processes Integrated with Biological Methods

In the last 3 years alone, over 10,000 publications have appeared on the topic of dye removal, including over 300 reviews. Thus, the topic is very relevant, although there are few articles on the practical applications on an industrial scale of the results obtained in research laboratories. Therefore, in this review, we focus on advanced oxidation methods integrated with biological methods, widely recognized as highly efficient treatments for recalcitrant wastewater, that have the best chance of industrial application. It is extremely important to know all the phenomena and mechanisms that occur during the process of removing dyestuffs and the products of their degradation from wastewater to prevent their penetration into drinking water sources. Therefore, particular attention is paid to understanding the mechanisms of both chemical and biological degradation of dyes, and the kinetics of these processes, which are important from a design point of view, as well as the performance and implementation of these operations on a larger scale.

“…Lastly, a combined anaerobic–aerobic biological treatment process was developed to treat textile wastewater (Shoukat, Khan, & Jamal, 2019). The combined system is composed of both anaerobic and aerobic sequencing batch reactors and obtained satisfying removal efficiency: 99.5% of COD, 78.4% of color, and 99.3% of total Kjeldahl nitrogen removal at 54 hs of hydraulic retention time.…”

The following is a review of published literature on textile wastewater in 2019. Presented are the sections described for the review: concise introduction on the textiles wastewater, followed by a review of present textile treatment technologies organized by physicochemical, biological, and combined processes. Lastly, a discussion of the future topics is presented. © 2020 Water Environment Federation • Practitioner points • The discharge of textile dye wastewater represents a serious environmental problem and public health concern. • Effluents from textile manufacturing, dyeing, and finishing processes contain highconcentration recalcitrant chemicals that are resistant to biodegradation. • The textile wastewater needs environmental-friendly and cost-effective combined treatment process.
