“…Comparing the literature data as follows, the water permeability (using pure water) of the alumina-coated diatomite–kaolin composite support layer was acceptable. The water permeability (using pure water) of one alumina-coated alumina support layer (with an average pore size of 0.27 µm and with a heat treatment at 1300°C for 2 h) [26] and another alumina-coated alumina support layer (with an average pore size of 0.6 µm and with a heat treatment at 1400°C for 3 h) [24], the other alumina-coated alumina support layer (with an average pore size of 0.1 ∼ 0.2 µm and a heat treatment at 1200°C) [27], and a clay-coated silty marls support layer (with an average pore size of 0.18 µm and a heat treatment at 900°C for 2 h) [28] were 441 L m −2 h −1 bar −1 , 8.0 L m −2 h −1 bar −1 , 320 L m −2 h −1 bar −1 , and 867 L m −2 h −1 bar −1 , respectively. In addition, from the point of the view of support layer alone, the water permeability (using pure water) of a silicon carbide support layer (with an average pore size of 0.5 µm) [29], a silica-based support layer (with an average pore size of 1.3 µm) [30], and an alumina–titania composite support layer (with an average pore size of 1 ∼ 2 µm) [31] were 1300 ∼ 1800 L m −2 h −1 bar −1 , 2.0 × 10 3 L m −2 h −1 bar −1 , and 145 ∼ 653 L m −2 h −1 bar −1 , respectively.…”

Porous ceramic membranes are a current research focus because of their outstanding thermal and chemical stability. Recent research has utilised inexpensive natural materials such as diatomite to reduce the expense of these porous ceramic membranes. However, insufficient data exist for microfiltration applications using the diatomite-based membranes. The measured membrane properties of alumina-coated alumina support layers and aluminacoated diatomite-kaolin composite support layers have been compared. These experiments have been used to determine whether the average pore size could be reduced effectively by controlling the thickness of the alumina coating layer, while maintaining acceptable water permeability. The membrane properties of the alumina-coated alumina support layers and the alumina-coated diatomite-kaolin composite support layers were examined using the scanning electron microscopy, mercury porosimetry, and a dead-end microfiltration system.

“…As a result, the treatment of organics in water has garnered increased attention. At present, the main treatment methods for organics in wastewater include physical [ 5 , 6 ], chemical and biological methods [ 7 , 8 , 9 , 10 , 11 , 12 ], or a combination thereof [ 13 , 14 , 15 ]. Among others, advanced oxidation methods showed potential advantages in treating organics, including the generation of reactive free radicals with strong oxidizing abilities, an effective degradation of organics and a better mineralizing effect [ 16 ].…”

N-Doped Biochar as a New Metal-Free Activator of Peroxymonosulfate for Singlet Oxygen-Dominated Catalytic Degradation of Acid Orange 7

In this paper, using rice straw as a raw material and urea as a nitrogen precursor, a composite catalyst (a nitrogen-doped rice straw biochar at the pyrolysis temperature of 800 °C, recorded as NRSBC800) was synthesized by one-step pyrolysis. NRSBC800 was then characterized using XPS, BET, TEM and other technologies, and its catalytic performance as an activator for permonosulfate (PMS) to degrade acid orange 7 (AO7) was studied. The results show that the introduction of N-doping significantly improved the catalytic performance of NRSBC800. The NRSBC800/PMS oxidation system could fully degrade AO7 within 30 min, with the reaction rate constant (2.1 × 10 −1 min−1) being 38 times that of RSBC800 (5.5 × 10−3 min−1). Moreover, NRSBC800 not only had better catalytic performance than traditional metal oxides (Co3O4 and Fe3O4) and carbon nanomaterial (CNT) but also received less impact from environmental water factors (such as anions and humic acids) during the catalytic degradation process. In addition, a quenching test and electron paramagnetic resonance (EPR) research both indicated that AO7 degradation relied mainly on non-free radical oxidation (primarily singlet oxygen (1O2)). A recycling experiment further demonstrated NRSBC800’s high stability after recycling three times.

“…Polymeric membranes cannot be utilized at elevated temperatures or drastic chemical conditions (Kujawski et al 2016). To overcome their disadvantages, numerous studies and development of inorganic membranes such as ceramic membranes have been performed recently (Yun et al 2015). Due to their excellent chemical resistance to inorganic acids and oxidants, the tolerance to high temperatures and pressures, and longer life span, application of ceramic membranes has increased over the last decades (Loganathan et al 2015;Ramakrishnan et al 2015).…”

The commercial method for isolation of ampelopsin, one of the most common flavonoids isolated from the plant species Ampelopsis grossedentata, is a simple hydrothermal extraction at high temperature. To develop an improved process to isolate ampelopsin, the effects of treatment of cellulase on hydrolysis of the dried fruit of A. grossedentata were investigated. The treatment of cellulase was found to decrease the temperature and time for hydrolysis of the dried fruit of A. grossedentata. The conditions of the filter press and continuous flow centrifuge for removal of insoluble materials from the hydrolysate of the dried fruit of A. grossedentata were optimized. The recovery yield of ampelopsin from the dried fruits of A. grossedentata was 39.4%, as determined by HPLC chromatographic analysis. A safe and economical process at low temperature with treatment of cellulase for the isolation of ampelopsin was developed in this study.
