“…Despite the efficiency, persulfate still has some drawbacks. e efficiency depends on generating a high amount of free radical [6] and high-cost operation [7]. Moreover, most of the dyes are resistant to AOPs and biological degradation [2].…”

In recent years, nanoparticles synthesis by green synthesis has gained extensive attention as a facile, inexpensive, and environmentally friendly method compared with chemical and physical synthesis methods. This review covered the biosynthesis of zinc oxide nanoparticles (ZnO NPs), including the procedure and mechanism. Factors affecting the formation of ZnO NPs are discussed. The presence of active bioorganic molecules in plant extract played a vital role in the formation of ZnO NPs as a natural green medium in the metallic ion reduction processes. ZnO NPs exhibit attractive photocatalysis properties due to electrochemical stability, high electron mobility, and large surface area. In this review, the procedure and mechanism of the ZnO photocatalysis process are studied. The effects of dyes amount, catalysts, and light on photodegradation efficiency are also considered. This review provides useful information for researchers who are dealing with green synthesis of ZnO NPs. Moreover, it can provide investigators with different perceptions towards the efficiency of biosynthesized ZnO NPs on dyes degradation and its restrictions.

“…The optimum coagulant dosage of alum, Fe 2 (SO 4 ) 3 and CuSO 4 is 1.0 g/L. It was reported that increasing the coagulant dosage from 5 to 15 g/L in the treatment of high strength raw vinasse can increase total organic carbon (TOC) removal (Fagier et al 2016). The charge neutralization explains the occurrence of the optimal coagulant dose.…”

Sugarcane vinasse has been widely reported due to the improper management that pollutes the environment. In this study, a combined coagulation and sequencing batch bio lm reactor (SBBR) seems to be a novel improvement for the treatment of sugarcane vinasse. This research focused on the optimal conditions of coagulation and SBBR and determined the abatement e ciency of sugarcane vinasse in combined sequential wastewater treatment. The coagulation process destabilizes the colloids in the aggregation and separates the supernatant by sedimentation and ltration, resulting in the maximum COD reduction (79.0 ± 3.4%) and decolorization e ciency (94.1 ± 1.9%) under the optimum conditions. Sequencing batch reactor (SBR) is a ll-and-draw activated sludge system, whereas SBBR is an integrated SBR that suspends activated sludge and connects growth processes into a biocarrier-lled system. SBBR showed great synergistic degradability, decreasing 86.6 ± 4.3% COD concentration and 94.6 ± 3.8% decolorization at 3.0 g/L of substrate loading concentration. Furthermore, kinetic studies of SBBR revealed that the rst-order kinetic model was the best tting model. The SBBR reaction was further investigated by ultraviolet-visible spectrophotometry (UV-Vis). Then, SBBR followed by the coagulation process (SBBR-CP) achieved 97.5% of COD reduction and 99.4% of decolorization, which was better than the coagulation process followed by SBBR (CP-SBBR). This nding provides new insight into developing e cient combined sequential wastewater treatments in sugarcane vinasse.

“…According to Álvarez (2021), vinasse contains high organic matter, high lipid concentration, low pH, and high COD and BOD content (Hoarau et al, 2018). Consequently, its discharge poses environmental problems, leading to water pollution, which usually occurs in irrigation on agricultural land (Álvarez et al, 2021;Christofoletti et al, 2013;Fagier et al, 2016). Therefore, disposing of unprocessed vinasse in aquatic and terrestrial environments can pose environmental risks (Reis et al, 2019;Fito et al, 2019).…”

Vinasse liquid waste is a waste product resulting from the ethanol distillation process. Phosphate in high concentrations can harm the environment, such as by polluting water sources and underground surfaces. In this research, adsorption of phosphate ions was carried out in vinasse waste to remove these pollutants using quaternary ammonium polymers. The study examined the effect of vinasse waste sample temperature on the adsorption of phosphate ions. The first step in this work was to create a quaternary ammonium polymer utilising a one-pot technique using 2-[methacryloyloxy)ethyl trimethylammonium chloride solution, also referred to as META. Subsequently, the adsorption process was performed using temperature variations of 25, 30, 40, 50, and 60 . Phosphate ion adsorbance was measured with UV-Vis spectrometers at a wavelength of 880 nm. The quaternary ammonium polymer succeeded in adsorbing the phosphate ion content of the vinasse waste at an optimal temperature of 40 , with an adsorption capacity of 3.78 mg/L and a removal efficiency of 75.70%. The adsorption isotherm model for phosphate ions onto quaternary ammonium polymer was studied using the Freundlich and Langmuir equations. The obtained data indicated that the Langmuir isotherm model, with an value of 0.9921, is well-suited for describing the adsorption behaviour in this research.
