Ceramic membranes originated from cost-effective and abundant natural minerals and industrial wastes for broad applications – a review

Desalination and Water Treatment (2020)

Linquan Sun Ziyi Wang Bao-yu Gao

The wide application of ceramic membranes in nowadays can be rationalized by their intrinsic properties, notably in terms of thermal and chemical stability and high mechanical strength.Compared to the conventional metal oxide materials, this article summarized comprehensively the natural minerals and industrial wastes, which are in abundance and need lower firing temperature, for the ceramic membrane fabrication as the raw materials.These cost-effective ceramic membranes prepared from clay, silty marls, kaolin, zeolite, bauxite, quartz sands, bentonite, cordierite, apatite, perovskite, coal fly ash, coal gangue, blast furnace slag, rice husk ash, pozzolan, etc. have emphasized the remarkable cost reduction and been broadly applicable to a variety of fields like removal of solid, dye, ion, heavy metal, oily wastewater treatment, juice clarification, seawater desalination, sterilization, hydrogen separation, oxygen permeation, CO 2 adsorption and separation, membrane catalysis, etc.The cost of these natural minerals and industrial wastes based ceramic membrane was estimated several times cheaper than the conventional oxide ceramic membrane.This review encouraged a more economically viable and environmentally sustainable strategy, not only giving a new and facile insight for waste management but also endow a possibility of high-valued recycling.

A pilot-scale test on the treatment of biological pretreated leachate by the synergy of ozonation-biological treatment-catalytic ozonation

Environmental Engineering Research (2020)

Yuanmei Chen Yutang Xiao Guanping Wang Wei Shi Linquan Sun

In this pilot-scale test, the ozonation-biological treatment-catalytic ozonation system was performed to treat complex organics and highly-concentrated total nitrogen (TN) in biological pretreated incineration leachate. The test results showed that the ratio of five-day biochemical oxygen demand (BOD5) / chemical oxygen demand (COD) increased from 0.059 to 0.237, which indicated that the concentration of biodegradable COD (CODbio) increased by ozonation pre-treatment process. In addition, the TN removal mainly occurred in anaerobic zone due to direct denitrification by the activated bacteria, which were domesticated through different influent ratio. Moreover, it was necessary to add catalytic ozonation process to reach higher direct effluent discharge criteria. After 60 days repeated debugging, the removal rate of COD and TN reached 88.5% and 98.2%, respectively. Finally, the total cost of this system was ￥ 6.65 /m<sup>3</sup> ($ 0.95 /m<sup>3</sup>), which was acceptable for the treatment of biological pretreated leachate. This pilot-scale test could provide some guiding information for the treatment of leachate containing highly-concentrated TN with low CODbio/N by the composite system.

Pilot-Scale Study of an Integrated Membrane-Aerated Biofilm Reactor System on Urban River Remediation

Industrial & Engineering Chemistry Research (2016)

Mei Li Peng Li Chunyu Du Linquan Sun Baoan Li

Coupled with the hydrolysis–acidification (H–A) process, the two-stage continuous flow membrane-aerated biofilm reactor (MABR) system was designed for urban river treatment, and parameter optimization was investigated in accordance with the average effluent concentrations of chemical oxygen demand (COD), ammonia nitrogen (NH4+–N), total nitrogen (TN), and suspended solids (SS). The optimal process parameters included temperature, 19 °C; pH, 8.0; the reflux ratio, 200%; and hydraulic retention time (HRT), 15 h, based on which the operational feasibility of the integrated system was further evaluated during the 40 days pilot-study for the urban river treatment. Results indicated that the integrated system exhibited highly effective performance for the urban river remediation with ∼87% COD removed and >95% NH4+–N removed. Nitrification and denitrification were simultaneously achieved inside the system. The TN removal process was enhanced by the reflux system with the effluent TN concentration remaining at ∼1.8 mg/L. The systematic applicability for the water quality improvement of the urban river was effectually confirmed on the pilot-scale study, which was conducive to the technical engineering application.

Research progress on status of environmental pollutions of polybrominated diphenyl ethers, hexabromocyclodocane, and tetrabromobisphenol A: A review

Environmental Chemistry (2021)

WU Yuli Xiao Yu-tang Guanping Wang Shi Wei Linquan Sun

Polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCD), and tetrabromobisphenol A (TBBPA) are the main traditional brominated flame retardants (BFRs). Owing to the property of Semi-volatility, persistance, and mobility, they are all found in various environmental media and organisms all over the world. Toxicological studies have shown that PBDEs, HBCD, and TBBPA not only exhibited obvious biological toxicity and carcinogenicity, but also posed potential harm to the ecological environment and human. This paper briefly summarized the current status of PBDEs, HBCD, and TBBPA in the environment, and discussed the level, distribution, exposure routes and toxicity of three traditional BFRs in non-living organisms (dust, water, soil, sediment, sludge) and living organisms (plants, animals, and humans). In addition, the problems existing in nowadays research were mentioned. Finally, a preliminary outlook for future research on PBDEs, HBCD, and TBBPA was presented.

Study on the Occurrence of Gallium in Gallium-Enriched Coal Gangue and Migration During Thermal Treatment

Yiyao Liu Haijian Yang Linquan Sun Jinji Yuan Keji Wan

The occurrence of gallium in gallium-enriched coal gangue and the migration of gallium during thermal treatment were systematically studied. The phase and chemical composition were determined, and especially the gallium content was determined by inductively coupled plasma mass spectrometer (ICP-MS). The mineralogical characteristics of coal gangue and liberation characteristics of main mineral phases where gallium occurs were analyzed using mineral liberation analyzer (MLA). The migration and occurrence of gallium in coal gangue during phase evolution after heat treatment were investigated through thermogravimetric and differential scanning calorimetry (TG-DSC) and step sequential chemical extraction procedure (SCEP). The results show that the main minerals in the coal gangue are kaolinite, pyrite, and illite, and the gallium content is 38.82 ppm, of which about 84% is present in kaolinite. It is indicated that gallium mainly occurs in aluminosilicate minerals, generally in the form of isomorphism, while a small proportion of gallium presents as adsorption state in pyrite and calcite. MLA results reveal that kaolinite in coal gangue shows a good liberation degree, while calcite and pyrite are encapsulated with each other, reflecting lower liberation characteristics. Organic matter combustion, pyrite oxidation, calcite decomposition, aluminum silicate dehydroxylation (transformation from kaolinite to metakaolin), and conversion of metakaolin into mullite sequentially occur during thermal treatment for coal gangue. As the mineral phases evolve, gallium gradually migrates from the aluminosilicate phase, predominantly kaolinite, to the carbonate and iron oxide phases, and then to mullite at 1000 °C. Present work sheds light on the efficient utilization for coal gangue in terms of beneficiation and gallium extraction.
