This book was released on 2012 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural Organic Matter (NOM) in surface water usually refers to humic and fulvic acids that are decayed by-products of plants such as those found in surface waters shallow well aquifers. Performance on humic acid removal from natural organic matter using Nanofiltration (NF) has been investigated in this study. Since most of the organic matter in groundwaterhas smaller between 200-500 D of the pore sizes, the useof the NF process was proposed. Thin-film composite nanofiltration membranes were prepared via interfacial polymerization of triethanolamine and trimesoyl chloride with different concentration and reaction time. The separation process was conducted by separating solution that contains humic acid to get the best result based on varying the concentration and reaction time for interfacial polymerization. In term of concentration of monomers has shown that 4% TEOA has gives more rejection of humic acid. As for reaction time, meanwhile10 minutes of TMC reaction time shows higher performance in removing humic acid. Fouling is still occur because of the tendency of humic acids appears to be dueto their ability to bind to multivalent salts.

This book was released on 2013 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: The polyester composite nanofiltration (NF) membrane has been prepared by interfacial polymerization for natural organic matter (NOM) removal. The effect of reaction time on the production of thin film composite NF and it affect on the NOM and Sodium Chloride (NaCl) removal performance was conducted. The thin film composite membranes were synthesized through interfacial polymerization with monomer concentration of 2% w/v of triethanolamine (TEOA) and then react with organic solution of trimesoylchloride (TMC) at different reaction time to produce a new layer polyester on top of polyethersulfone (PES) miroporous support. The fabricated thin film composite membranes were characterized in term of water flux and permeability. It was found that the Polyester NF membrane with different reaction time (15, 25 and 35 minute) which prepared through interfacial polymerization can reduce the humic acid concentration. Besides that, the variation of reaction time in interfacial polymerization technique improved the filtration performance of the membrane. The result shows that the flux and permeability were decreased as the reaction time increased while opposite trend for NOM and NaCl rejections were observed.

Download or read book Nanofiltration written by Muhammad Akhyar Farrukh and published by BoD – Books on Demand. This book was released on 2018-07-11 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nanofiltration technique lies between ultrafiltration and reverse osmosis techniques, and it is considered a low-cost process and is capable of removing pesticides, organic matter, desalination of sea water, oil process and pollutants from industrial wastewater. However, the main challenge in implementation of nanofiltration membrane is its ability towards fouling and low performance at high temperature. The use of nanoparticles in the manufacturing of membranes allows for a high degree of control over membrane fouling. Nanoparticle-based membranes can be developed by assembling engineered nanoparticles into porous membranes or blending them with polymeric or inorganic membranes. This book covers topics from multiple ranges from manufacturing of nanofiltration membranes and their applications in wastewater treatment, drinking water treatment, and removal of pollutants, to addressing the fouling issues.

Download or read book Effects of High Concentrations of Organic and Inorganic Pollutants in Waste Water and Drinking Water on Nanofiltration Membrane Behavior written by Nikoleta Kukučka Stojanović and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Removal possibility of high concentrations of organic and inorganic matter from aquatic solution using "Crossflow" spiral wound nanofiltration membranes was investigated on a self-made semi-industrial pilot plant, capacity 800 L/h. Natural organic matter, ammonia ions, and total arsenic removal were examined using concentrates-waste water obtained from industrial nanofiltration plant. Nanofiltration of waste water provided conclusions that arsenic was better removed in higher organic concentration environment rather than in lower. Also, membranes removed organic carbon with high efficiency and produced drinking water quality permeate. Removal of high concentrations of total iron, manganese, calcium, and magnesium was conducted using natural groundwater with and without the presence of complexing agent. Obtained results show that molecular weight cutoff, as well as quantity and type of complexing agent, had an influence on measured parameter removal. Also, electrostatic forces influenced separation of investigated ions.
