Book Synopsis Simultaneous Removal of Benzene and Copper from Water and Wastewater Using Micellar-enhanced Ultrafiltration by : Mohammed Ridha Zaid Ahmed
Download or read book Simultaneous Removal of Benzene and Copper from Water and Wastewater Using Micellar-enhanced Ultrafiltration written by Mohammed Ridha Zaid Ahmed and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: To remove metal ions and/or organic molecules from aqueous solutions is a difficulty commonly encountered in the treatment of contaminated water. Traditional ultrafiltration is usually used to separate the high molecular weight molecules and is ineffective in removing heavy metal ions or organic molecules with small molecular weights. Micellar-enhanced ultrafiltration (MEUF) is an effective technique to remove contaminants that traditional ultrafiltration cannot remove. Micellar-enhanced ultrafiltration makes use of the micellar properties of surfactant solutions to remove dissolved ions and/or organics from aqueous streams. Chemical surfactants have proven effective. However compared to biosurfactants they are toxic and create a secondary problem since part of the surfactant monomers frequently leak through the pores of membrane filters. This study is an attempt to examine the effect of rhamnolipid biosurfactant, JBR 425, on contaminant removal from aqueous solutions. The required quantity of rhamnolipid to remove the copper ions as a heavy metal pollutant and benzene molecules as an organic pollutant separately has been determined for different concentrations of pollutants. This quantity, the molar ratio (MR), was 6.25 to obtain a 100% rejection for the copper ions and 1.33 to obtain the same rejection of benzene molecules. When copper and benzene were mixed, these molar ratios have been either improved as in benzene molar ratio which was decreased from 1.33 to 0.56 or remained the same as in copper molar ratio but in all cases rhamnolipid JBR 425 proved of excellent efficiency in the removal of contaminants and a rejection of 100% has been obtained for copper and benzene either separately or simultaneously which is the objective of this study.

Download or read book Use of Ligand-modified Micellar-enhanced Ultrafiltration to Selectively Separate Copper Ions from Wastewater Streams written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The selective removal of target ions from an aqueous solution containing ions of like charge by ligand-modified micellar-enhanced ultrafiltration (LM-MEUF), is presented. In LM-MEUF, surfactant and specially tailored ligand are added to the contaminated stream. The surfactant forms aggregates called micelles, the hydrocarbon core of which the ligand complexed with the target species will solubilize. The surfactant is chosen to have the same charge type as the target ion; therefore, other ions (with similar charge) will not associate with the micelle, which makes the separation of the target ion selective. The solution is then processed by ultrafiltration, using a membrane with pore size small enough to block the passage of the micelles. In this study the divalent copper is the target ion in the solution containing divalent calcium. The surfactant is cetylpyridinium chloride (CPC) and the ligand is 4-hexadecyloxybenzyliminodiacetic acid (C[sub 16]BIDA). Experiments were conducted with batch stirred cells and the results have been compared to separation that take place under a variety of conditions in the LM-MEUF process. Rejections of copper of up to 99.8% are observed, with almost no rejection of calcium, showing that LM-MEUF has excellent selectivity and separation efficiency.
Book Synopsis Surfactant Recovery by Liquid-liquid Extraction and Reverse Micellar Extraction by :
Download or read book Surfactant Recovery by Liquid-liquid Extraction and Reverse Micellar Extraction written by and published by . This book was released on 2007 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study aimed to investigate two extraction techniques namely liquid-liquid extraction (LLE) and reverse micellar extraction coupled with ultrafiltration process for tetrachloroethylene (PCE) removal and surfactant recovery purposes. Using surfactant solution to remediate NAPLs gains more attractions. Nevertheless, prior reusing surfactant, a decontamination of surfactant solutions is recommended. In this study, we imitated the surfactant solution similar to one pumped out of the contaminated site, which contains 4%AMA (anionic surfactant), 3%NaCl and 10,000 ppm solubilized PCE. The conventional LLE using five extracting solvents varying the equivalent alkane carbon number (EACN) was investigated to determine the partitioning of PCE from surfactant solution into solvent phase and the %PCE removal. The reverse micellar extraction is another extraction technique based on Winsor type II microemulsion formation, where the micelles break up, migrate into the solvent phase and re-aggregate to form reverse micelles. The released PCE during the micelles break up also partitions into the solvent phase. The result showed that the EACN of extracting solvent and the surfactant solution:solvent volumetric ratio were crucial parameters governing the extraction efficiency of LLE. In addition, other parameters such as molecular structure and functional groups of solvent also have an influence on the PCE partitioning and PCE removal in LLE technique. For reverse micellar extraction, the surfactant solution:solvent volumetric ratio (ranged from 40:1 to 5:1) used in this study did not show significant effects on the surfactant removal (84.9-86.9%) and PCE removal (96.7-98.4%). Furthermore, an ultrafiltration process was used as an additional downstream process after reverse micellar extraction to concentrate the surfactant reverse micelles in the retentate, while passing PCE and solvent as the permeate stream.

This book was released on 2019-05-21 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents recent challenges related to new forms of pollution from industries and discusses adequate state-of-the-art technologies capable to remediate such forms of pollution. Over the past few decades the boom in the industrial sector has contributed to the release in the environment of pollutants that have no regulatory status and which may have significant impact on the health of humans and animals. These pollutants also referred to as "emerging pollutants", are mostly aromatic compounds which derive from excretion of pharmaceutical, industrial effluents and municipal discharge. It is recurrent these days to find water treatment plants which no longer produce water that fits the purpose of domestic consumption based on newly established guidelines. This situation has prompted water authorities and researchers to develop tools for proper prediction and control of the dispersion of pollutants in the environment to ensure that appropriate measures are taken to prevent the occurrence of outbreaks due to sudden load of these pollutants in the water system. The chapters in this book cover a wide range of nano and bio-based techniques that have been designed for the real time detection of emerging contaminants in environmental water sources, geochemical models that are continuously improved for the prediction of inorganic contaminants migration from the mine solid wastes into ground and surface waters. Remediation strategies are also discussed and include effective techniques based on nanotechnology, advanced membrane filtration, oxidative and bio-degradation processes using various types of nanocatalysts, biocatalysts or supporting polymer matrices which are under advanced investigations for their implementation at large scale for the removal of recalcitrant pollutants from polluted water. Nano and Bio-Based Technologies for Wastewater Treatment: Prediction and Control Tools for the Dispersion of Pollutants in the Environment is divided is two sections. The first section covers the occurrence of emerging pollutants in environmental water while the second section covers state-of-the-art research on the removal of emerging pollutants from water using sustainable technologies. A total of 13 chapters addressing various topics related to the two sections are essentially based on recent developments in the respective field which could have a significant impact on the enhancement of the performance of wastewater treatment plants around the world, and especially in developing countries where access to clean and safe water remains a daily challenge.
