Electrochemical characteristic parameters such as diffusional permeability, ion transport number, fi xed charge concentration and electrical resistance for a regenerated cellulose/polypropylene-supported membrane (RC/PP sample) in contact with NaCl solutions at different concentrations were determined. The effect of the polypropylene support on mass and charge transport was estimated by compari...

Nanotechnology is among the most revolutionary technologies in the world. The term nanotechnology describes a range of technologies performed on a nanometer scale with widespread applications as an enabling technology in various industries. Unlike other technologies, which have often sprung directly from a particular scientific discipline, nanotechnology spans a wide spectrum of science. Nanote...

Delhi, the capital city of India is facing many problems of water shortage which are exacerbated by the population growth, urbanization, industrialization and migration. As part of the WP 7.9 of the TECHNEAU integrated project, the feasibility of the OBM process combined with river bank filtration to provide a sustainable and safe drinking water supply for Delhi is investigated within this repo...

pulp and paper effluents are considered as serious environmental hazards and their treatment, because of multiplicity of impurities and complexity of their chemical structures, is one of the most difficult and inconvenient industrial processes. as the most pulp and paper mill work on kraft process, there are few studies in literature on the treatment of neural sulfite semi chemical (nssc) proce...

abstract background: dyes are visible materials and are considered as one of the hazardous components that make up the industrial waste. dye compounds in natural water, even in very low concentrations, will lead to environmental problems. azo dyes are compounds with one or more –n=n– groups and are used in textile industry. because of its low price, solubility, and stability, azo dyes are widel...

Due to the impact of climate change, the process of salinity intrusion occurs frequently in coastal areas of Vietnam. The main objective of this study is therefore to try diff erent nanofi ltration (NF) processes (such as single-stage and dual-stage NF) to treat brackish water for residential areas in Thu Bon river basin, where the salinity varies signifi cant with seas...
