Progress of Membrane Engineering for Water Treatment
Together with the supply of energy and the environmental protection, fresh water is one of the three keys elements for the sustainable development of every society. Where the availability of water cannot be carried out by using conventional sources, unavoidable appears the resort of the major water source: the sea. Today, RO is one the most used membrane processes for the production of fresh wa...
متن کاملA Review on Applications of Membrane Distillation (MD) Process for Wastewater Treatment
The growing scarcity of fresh water is driving the implementation of wastewater treatment and water reuse on an increasingly large scale. Various methods have been developed and used for water reuse from wastewater; however, the membrane distillation (MD) process, as a promising separation technology, has recently gained more attention. The MD process is a non-isothermal membrane-based separati...
متن کاملReview of Micro/Nanotechnologies for Microbial Biosensors
A microbial biosensor is an analytical device with a biologically integrated transducer that generates a measurable signal indicating the analyte concentration. This method is ideally suited for the analysis of extracellular chemicals and the environment, and for metabolic sensory regulation. Although microbial biosensors show promise for application in various detection fields, some limitation...
متن کاملA New Approach to Provide High Water Permeable Polyethersulfone based Nanofiltration Membrane by Air Plasma Treatment
In this study, polyethersulfone based nanofiltration membranes were modified by air plasma generated through dielectric barrier discharge to increase the membrane hydrophilicity aiming to improve the separation and antifouling characteristics. The effect of plasma time on the physico-chemical and separation properties of membrane was investigated. The PES nanofiltration membranes were fabricate...
متن کاملIncorporation of Graphene-Related Carbon Nanosheets in Membrane Fabrication for Water Treatment: A Review
The minimization of the trade-off between the flux and the selectivity of membranes is a key area that researchers are continually working to optimise, particularly in the area of fabrication of novel membranes. Flux versus selectivity issues apply in many industrial applications of membranes, for example the unwanted diffusion of methanol in fuel cells, retention of valuable proteins in downst...
