“…From the first stage, optimum coagulant dosage will be obtained. For the second stage, the coagulant dosage was fixed at the optimum coagulant dosage obtained from the first stage with ranges of pH (pH 2,4,6,8,10,12). From the second stage, the optimum pH of bagasse for optimum turbidity removal was obtained.…”

“…Different natural coagulant has different properties. For instance, Moringa oleifera seeds rely on their superior protein content while Jatropha curcas relies on its high carbohydrate or polysaccharide content which acts as an active coagulant agent [10]. Currently, researchers are still unable to conclude the main properties of these sources to be used as natural coagulants as different sources have different properties that make them suitable to be used as natural coagulants [11].…”

The performance of extracted coagulant from the sugarcane bagasse was tested using synthetic wastewater for turbidity removal. Sugarcane bagasse was selected because it is available in abundance as a waste. This study was carried out to analyze the effect of the extraction process in optimizing the active coagulant agent of bagasse as a natural coagulant for optimum turbidity removal. Bagasse was characterized in terms of physical, chemical and morphological properties. The results showed bagasse has very high polysaccharide content which can act as an active coagulant agent together with hemicellulose and lignin. The extraction process for degradation of lignin and hemicellulose was run based on two different solvents (NaOH and H2SO4) with varying concentrations from 2% to 10% at different extraction temperatures varied from 60 °C to 180 °C for various extraction times (0.5 h to 3 h). The optimum polysaccharide content extracted from bagasse was 697.5 mg/mL by using 2% NaOH at 120 °C for 2 h extraction. The coagulation process using extracted bagasse showed the removal of suspended solids up to 95.9% under optimum conditions. The concentration of polysaccharides as the active coagulant agent plays a vital role where high polysaccharides content removes most turbidity at a lower dosage. Bagasse has the potential to be an alternative coagulating agent due to its efficiency, and eco-friendly properties for the treatment of wastewater.

“…Let alone its role in strengthening the interfacial layer between oil and water, which became the main concern in this article. This principle has been exploited in wastewater treatment using the coagulationflocculation process described in the recent studies (Bahrodin et al, 2021;Fard et al, 2021;Iloamaeke et al, 2021). The pollutant removal efficiency was highly dictated by the wastewater pH depending on the coagulant agent and its mechanism (Bahrodin et al, 2021;Sibiyaet al, 2021).…”

Alum as the coagulant became soluble and positively charged in the acidic environment was easily adsorbed onto the negatively charged surface of the colloids leading to charge neutralization and pollutant removal (Bahrodin et al, 2021). Furthermore, the color removal efficiency increased as pH decreased from 10 to 2 when Mercenaria mercenaria shell with a zero-point charge value (pHzpc) of 7.8 used as the coagulant became positively charged thus, enhancing the coagulation of negatively charged colloid particles making them to floc due to the increase in the force of attraction which led to charge neutralization (Iloamaeke et al, 2021).…”

The awareness of the need for healthy food continues to increase, hence, the demand for healthy food is also increasing. Water-in-oil-in-water (W/O/W) double emulsion can provide lowfat emulsion-based products due to a lower fraction of oil compared to the corresponding O/W emulsion. However, the stability of double emulsion has been quite tricky to be established due to the presence of two interfacial layers between oil and water. This research aims to study the use of biosilica in the form of rice husk ash (RHA) combined with both chitosan particles and chitosan solution to stabilize the interfacial layer between oil droplets and the outer aqueous phase. The concentrations of chitosan and biosilica, as well as pH of the outer aqueous phase in the acidic ranges, were varied to obtain W/O/W emulsion with higher stability. The primary emulsion was prepared by using the emulsifier mixtures of Tween 20 and Span 80. The resulting primary emulsion was subsequently dispersed into the outer aqueous phase, loaded with the combination of biosilica and chitosan particles/ solution. Emulsification processes were conducted using a rotorstator homogenizer. The resulting W/O/W emulsions with high stability of ~80-100% were obtained by using the combination of 0.5% biosilica and 1.25% chitosan particles/ 5.25% chitosan solution at the pH of 4. The use of biosilica and chitosan seemed promising to be applied in the manufacturing of healthier food emulsion-based products.

This study focuses on the settling profile and chemical characteristics of latex aerobic granules cultivated from rubber industrial wastewater. Latex‐based aerobic granular sludge (AGS) was cultivated using sequencing batch reactor (SBR) in supplemented with synthetic wastewater (SW) as nutrients feeding for biogranulation process. The bioreactor was operated for 24 h with eight series of intermittent 3 h SBR cycles continuously. The SBR configuration comprises of five operation phases from SW feeding, aeration, settling, and effluent decanting to idle. Latex granules exhibit a loose and irregular structure dominated by coccal‐shaped bacteria with an average size of 4.0–5.0 mm and a settling velocity of 0.35–0.53 m h–1. The elemental analysis using X‐ray fluorescence (XRF) showed that the latex granules contained various elements while X‐Ray diffraction (XRD) analysis suggested the presence of zincowoodwardite, berlinite, rutile, and quartz. Fourier transform infrared spectroscopy (FTIR) analysis revealed the presence of aliphatic hydrocarbons, alkene, alkyne, and tertiary amine.
