Studies on Recovery of Chromium Form Tannery Wastewater by 29 Studies on Recovery of Chromium from Tannery Wastewater by Reverse Osmosis
Chromium (Cr) is the most important element used to leather industry is still considered to be the most important industries which pollute the environment by chromium metal. Removal of heavy metals dissolved at low concentrations in water and wastewaters is often a problem that can be solved in different ways. This paper describes a study conducted to determine the recovery of chromium from tan...
متن کاملPerformance study of ceramic microfiltration membrane for oily wastewater treatment
Cross-flow microfiltration (MF) processes were studied with oily wastewater using a ceramic ( -Al2O3) membrane with 50 nm pore size. The nfluence of parameters such as transmembrane pressure (TMP), cross-flow velocity (CFV), oil concentration in feed, pH and salt concentration n the separation behaviors were investigated by the measurements of permeate flux, total organic carbon (TOC) removal e...
متن کاملapplication of nanofiltration and reverse osmosis for tanning wastewater
the aim to achieve in this study is to recover the cr(iii) and process waters used in thewastewaters of chrome tanning operation by membrane process during leather production. in the treatmentalternative contains, cartridge filter, nanofiltration (nf(np10)), nanofiltration nf(xn45) and reverse osmosisro(acm2) membranes. the raw chrome wastewater from the cartridge filter was given to nf(np10)me...
متن کاملChromium 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 کاملapplication and optimization in chromium-contaminated wastewater treatment of the reverse osmosis technology
background: chromium (cr) is the most important element used to plate other metals and electroplating factories are still considered to be the most important industries which pollute the environment to this metal. this paper describes a study conducted to determine the efficiency of reverse-osmosis (ro) as a membrane technique for removal of cr from wastewater samples synthetically prepared ...
