Treatment of oily wastewater from cold-rolling mill through coagulation and integrated membrane processes

Chemical Cleaning of Utafiltration Membrane after Treatment of Oily Wastewater

Zwitterion Embedded Thin Film Composite Membrane for Oily Wastewater Treatment

The recent development in oil and gas industry increases the production and consumption of oil. The enormous amount of oily wastewater produced is urged to be treated to prevent humanity and environment from being threatened. Membrane technology is an appealing alternative for oily wastewater treatment due to its design simplicity, energy efficiency and environmentally benign approach. In this ...

Performance 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...

Treatment of Textile Wastewater Using a Combined Coagulation and DAF Processes, Iran, 2016

Background & Aims of the Study: There are three different types of fibers used in the manufacture of various textile products: cellulose fibers, protein fibers and synthetic fibers. Textile wastewater discharge into the environment leads to irreparable damages. The main purpose of this study was treatment of textile wastewater, using a combined coagulation and dissolved air flotation (DAF) ...

Complete Treatment of Compost Leachate Using Integrated Biological and Membrane Filtration Processes

A lab-scale SBR equipped with a flat sheet membrane in submerged configuration that is named MSBR was used for the treatment of composting leachate. It was fed by biologically treated leachate with overall 70-1360 mg/L Chemical Oxygen Demand (COD). The values of pH, Electrical Conductivity (EC), and Dissolved Oxygen (DO) were monitored r...
