“…The SUVA 254 values of the peat water sample in this study ranged at 2-3 L/mg.m suggesting the mixture of hydrophobic and hydrophilic substances NOM characteristics, with a large range of MWs. Similar results were found in previous research on surface water that reported SUVA 254 of < 2 L/mg.m (low hydrophobic character) [41,42].…”

“…It shows that the peat water had a neutral pH, similar to previous reports where the pH value on surface water ranged from 5.0-8.1 [31]. The high NOM content was indicated by the DOC values [39,40], the absorbance value of UV 254 , which are high compared with the results obtained by Kang and Choo [41] and Jeong et al [42] of UV 254 < 0.1 cm −1 for surface water. However, compared with the results obtained elsewhere Herwati, Mahmud, and Abdi [30], Mahmud, Abdi, and Mu'min [31], Saputra [37], Aisyahwalsiah [39] showed the UV 254 absorbance of the peat water samples was relatively low.…”

The high content of natural organic matter (NOM) is one of the challenging characteristics of peat water. It is also highly contaminated and contributes to some water-borne diseases. Before being used for potable purposes, peat water must undergo a series of treatments, particularly for NOM removal. This study investigated the effect of coagulation using aluminum sulfate coagulant and adsorption using powdered activated carbon (PAC) as a pretreatment of ultrafiltration (UF) for removal of NOM from actual peat water. After preparation and characterization of polysulfone (Psf)-based membrane, the system’s performance was evaluated using actual peat water, particularly on NOM removal and the UF performances. The coagulation and adsorption tests were done under variable dosings. Results show that pretreatment through coagulation–adsorption successfully removed most of the NOM. As such, the UF fouling propensity of the pretreated peat water was substantially lowered. The optimum aluminum sulfate dosing of 175 mg/L as the first pretreatment stage removed up to 75–78% NOM. Further treatment using the PAC-based adsorption process further increased 92–96% NOM removals at an optimum PAC dosing of 120 mg/L. The final UF-PSf treatment reached NOM removals of 95% with high filtration fluxes of up to 92.4 L/(m2.h). The combination of three treatment stages showed enhanced UF performance thanks to partial pre-removal of NOM that otherwise might cause severe membrane fouling.

“…Aerobic granular sludge (AGS) can form granular biopolymers by microbial selfaggregation under suitable conditions. Compared with conventional activated sludge (CAS), due to the advantages of good settlement [1,2], better resistance to shock loads [3], low occupied area [4,5] and rich in microorganisms [6], the potential applications of AGS technology are promising [1,7]. Since Mishillla et al [8] first discovered AGS, the technology has gone through nearly 30 years of development and practice.…”

Current extensive research on aerobic granular sludge (AGS) largely focuses on improving its microbial biodiversity, settlement behavior, nitrogen and phosphorus removal efficiency, and shock load resistance. Great challenges that have to be faced are the bottleneck of slow-speed granulation and easy disintegration after granulation, which are key to the extended application of AGS technology. In the present review, the typical morphological structures of AGS are firstly summarized as well as the granulation model hypotheses, and then, we analyze the dominant microflora and their spatial distribution features. The influencing factors on particle structure stability are discussed thereafter on a macro and micro scale. Prospects and future research trends are also discussed based on the current study results for AGS technology.

“…Photocatalytic degradation of organic pollutants and sorption/photocatalytic reduction of metal ions under visible light irradiation is a useful method for the efficient degradation of organic molecules or in-situ solidification of metal ions, especially at low concentrations. In this section, we mainly discussed the photocatalytic degradation of organic pollutants and photocatalytic degradation of heavy metal ions [60,61].…”
