Komurcuoda leachate treatment plant, Istanbul, which consists of membrane bioreactor (MBR) and nanofiltration (NF) system, faced rapid flux decline in membranes after 3-year successful operation. To compensate rapid flux decline in membranes, the fouled membranes were renewed but replacement of the membranes did not solve the problem. To find the reasons and make a comprehensive analysis, membr...

To meet the increasing global water demand, local solutions, such as reuse of greywater, are becoming greater importance. While greywater reclamation has been implemented, full-scale adaptation limited by occurrence micropollutants in treated effluent. reduce risks posed micropollutants, advanced post-treatment is required. One promising technology implementation hollow fiber nanofiltration, wh...

Water shortage severely restricts vegetation restoration of mining area in the northwest China. Moderate treatment reclaimed water is essential for improving local ecological environment. In this study, relevant quality standards issued by states and research results were comprehensively considered to propose a standard suitable area. The available domestic sewage mine was moderately treated hy...

Nanofiltration (NF) is an attractive option for the treatment of landfill leachate. However, membrane fouling can be a major obstacle in the implementation of this technology. In this study, bench-scale filtration experiments were carried out to study the fouling behaviour during the NF of a synthetic landfill leachate. The results indicate that calcium in combination with organic matter could ...

This study focuses on the application of combining membrane bioreactor (MBR) treatment with reverse osmosis (RO) or nanofiltration (NF) membrane treatment for removal of pharmaceuticals and personal care products (PPCPs) in municipal wastewater. Twenty-seven PPCPs were measured in real influent with lowest average concentration being trimethoprim (7.12 ng/L) and the highest being caffeine (18.4...

The performance of a polyamide-based thin film composite reverse osmosis membrane (RO) in a spiralwound element BW3025 (FilmTec) for the recovery of caprolactam from an aqueous solution have been investigated. The experimental tests of the RO membrane were carried out using pure water (permeate from a nanofiltration system), brackish water (2000 ppm NaCl) and caprolactam solution (1000 ppm) and...

The widespread occurrence of endocrine disrupting chemicals (EDCs), such as steroid hormones, in secondary wastewater effluents has become a major concern in the water recycling practice. This paper investigates the risk of steroid hormone breakthrough during nanofiltration membrane filtration in water recycling applications. The results indicate a dynamic equilibrium between adsorption and des...

Abstract Humanity is facing a global challenge of dwindling water resources and the situation intensifying due to growing population leading excessive pollution. Nanofiltration an important membrane-based technology for production clean potable domestic industrial setups. Hyper-cross-linked polyamide thin film composite nanofiltration (HCPA-TFC-NF) membranes have been fabricated by using multif...

Abstract Poly (m-phenylene isophthalamide) (PMIA) membranes are prepared via evaporating part solvent of the casting solution before its nonsolvent-induced phase separation. Zeolite imidazolate framework-8 (ZIF-8) is added into PMIA as an inorganic filler to improve filtration capability membrane. The structure composite characterized by scanning electron microscopy (SEM), Zeta-potential analyz...
