Chromium Removal from Wastewater by Reverse Osmosis
This study describes the removal of chromium from wastewater using pressure-driven membrane separation processes. It describes the rejection of trivalent chromium using a commercial membrane for reverse osmosis typed RO98pHt (Alfa Laval, Sweden). Model solutions of chromium were used for performing of separation experiments. The effects of feed pH, chromium concentration and temperature were in...
متن کاملExperimental study of dye removal from industrial wastewater by membrane technologies of reverse osmosis and nanofiltration
Currently, biological method has been utilized in the treatment of wastewater -containing synthetic dyes used by textile industries in Iraq. The present work was devoted to study the operating feasibility using reverse osmosis (RO) and nanofiltration (NF) membrane systems as an alternative treatment method of wastewater discharged from Iraqi textile mills. Acid red, reactive black and reactive ...
متن کاملEffect 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 کاملFouling and cleaning of reverse osmosis membrane applied to membrane bioreactor effluent treating textile wastewater
Membrane bioreactor (MBR) and reverse osmosis (RO) membrane system was applied to the treatment and reclamation of textile wastewater in Thailand. An experiment was carried out to determine the fouling behavior and effect of anti-scalant and biocide addition to flux decline and its recovery through chemical cleaning. The RO unit was operated for one month after which the fouled membranes were c...
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...
