Effect of Organoclay on the Performance of Reverse Osmosis Membrane
This study investigated the effect of Cloisite15A (C15A) organoclay in the substrate layer on the performance of reverse osmosis (RO) membranes. The substrate of the RO membranes was modified using different loading of C15A (ranging from 0.3 - 0.7 wt%) within polysulfone (PSf) substrate and the polyamide (PA) selective layer was formed on the top. Effect of the modified substrate layer on the w...
متن کاملThe Effect of Osmotic Dehydration on Reverse Osmosis Membrane Performance
Akin type (asymmetric) reverse osmosis membranes undergo an irreversible osmotic dehydration upon coming into contact (skin side) with salt solutions. The extent of consequent changes (in appearance; decrease in linear dimension, water flux and salt rejection) are dependent on the salt concentration. These observations are correlated with the expected morphological changes taking place duri...
متن کاملAn autopsy study of a fouled reverse osmosis membrane element used in a brackish water treatment plant.
The fouling of a spiral wound reverse osmosis (RO) membrane after nearly 1 year of service in a brackish water treatment plant was investigated using optical and electron microscopic methods, Fourier transform infrared spectroscopy (FTIR) and inductively coupled plasma atomic emission spectrometry (ICP-AES). Both the top surface and the cross-section of the fouled membrane were analysed to moni...
متن کاملEngineering Aspects of Reverse Osmosis Module Design
During the half century of development from a laboratory discovery to plants capable of producing up to half a million tons of desalinated seawater per day, Reverse Osmosis (RO) technology has undergone rapid transition. This transition process has caused signification transformation and consolidation in membrane chemistry, module design, and RO plant configuration and operation. From the early...
متن کاملInvestigation of the Effect of Copolymer Antiscalant on TDS Removal Efficiency in Reverse Osmosis Membrane
Background & objectives: Nowadays, according to membrane-based filtration processes; the use of substances such as antiscalants that prevents the formation of deposits during the treatment process, is very important from industrial point of view. This study aimed to synthesize styrene-maleic anhydride copolymer (PSMA) using the radical polymerization method and to investigate the factors and pa...
