“…These regions need inventive and viable approaches for safe water supply to support population growth. Since 1980, filtration systems equipped with nanoporous membranes have been commercialized and membrane separation has become a rapidly emerging technology in many industrial applications such as food industry, petroleum industry, chemical processing industry, pulp and paper industry, pharmaceuticals and electronic industry [9,10,11,12,13,14]. In these industries, wastewater purification is an essential process that involves membrane separation technique.…”

Sustainable and affordable supply of clean, safe, and adequate water is one of the most challenging issues facing the world. Membrane separation technology is one of the most cost-effective and widely applied technologies for water purification. Polymeric membranes such as cellulose-based (CA) membranes and thin-film composite (TFC) membranes have dominated the industry since 1980. Although further development of polymeric membranes for better performance is laborious, the research findings and sustained progress in inorganic membrane development have grown fast and solve some remaining problems. In addition to conventional ceramic metal oxide membranes, membranes prepared by graphene oxide (GO), carbon nanotubes (CNTs), and mixed matrix materials (MMMs) have attracted enormous attention due to their desirable properties such as tunable pore structure, excellent chemical, mechanical, and thermal tolerance, good salt rejection and/or high water permeability. This review provides insight into synthesis approaches and structural properties of recent reverse osmosis (RO) and nanofiltration (NF) membranes which are used to retain dissolved species such as heavy metals, electrolytes, and inorganic salts in various aqueous solutions. A specific focus has been placed on introducing and comparing water purification performance of different classes of polymeric and ceramic membranes in related water treatment industries. Furthermore, the development challenges and research opportunities of organic and inorganic membranes are discussed and the further perspectives are analyzed.

“…To meet the diversified needs of the market, there are many kinds and specifications of tissue paper products, which make it necessary to use different kinds of fiber raw materials in the production processes, and at the same time, a variety of process paths have been developed accordingly. The paper industry has a long industrial chain; the upstream involves the growth, collection of plant raw materials, and energy mining, while the midstream involves the process of energy processing, chemical production, pulping, and papermaking, with various modes of transport running through it …”

The paper industry is characterized by a long industrial chain and diverse production paths. Under different production paths, the sustainability evaluation results of criteria are different, so there is a decision problem of the most sustainable production path. At present, the sustainability evaluation researches of the paper industry usually make a quantitative comparison of single or multiple evaluation criteria, respectively, and lack the integration of multiple criteria to make the overall optimal production path. This study selects the tissue paper industry as a case and takes the life cycle water consumption, energy consumption, greenhouse gas (GHG) emissions, and internal costs as evaluation criteria. Two multi-criteria decisionmaking (MCDM) models, the interval sum weighted method and technique for order preference by similarity to an ideal solution, are used to obtain the sustainability rankings of seven different production paths for tissue paper. The results show that the production path based on natural sulfate bamboo pulp has the highest sustainability, while the production path based on bleached kraft pulp has the lowest sustainability. The sensitivity analysis of the two MCDM models is carried out by changing the weight of the criteria. It is found that the bleaching operation has a significant impact on the sustainability ranking of production paths. The production paths based on wood pulp and bamboo pulp are superior in terms of water consumption, energy consumption, and GHG emissions, while the production paths based on straw pulp and bagasse pulp are superior in terms of internal costs. The method proposed in this study will also provide ideas for the sustainability assessment of other industrial processes.

“…China has adopted many policies to explore ways of water resources management, and many scholars have conducted a lot of research [5,6], but there are still some deficiencies [7]. To balance the uneven distribution of water resources between the south and north, China's South-to-North Water Diversion Project (SNWDP) began construction in 2002.…”

Water quality assurance is the primary factor for the successful operation of water diversion projects across river basins. The rapid prediction of water pollution is the basis for timely and effective emergency control and disposal measures. In China, since the open channels intersect with numerous waterways and traffic arteries, water transfer projects are prone to sudden water pollution accidents. In this paper, the rapid prediction method was developed for sudden water pollution accidents that possibly occurred in the East Route of the South-to-North Water Diversion Project (ERP) in Shandong Province. With the empirical formula of the pollution transfer law, a rapid prediction model of water quality (WQRP) was established based on the simulation of the typical accidents in the main channel. Finally, four typical accidents were selected as application examples, and the prediction results were compared with the results from a computer numerical simulation to demonstrate the validity of the model. The results showed that the prediction results by the WQRP model meet the accuracy requirements. This method is of great significance for providing water transport security in the extreme conditions of long-distance water transfer projects.
