Analysis of Membrane Methods Application for Treatment of Textile Wastewater

Abstract

Wastewater of textile enterprises may be significantly different in concentration of main pollutants and thus implemented methods of treatment. The technological solutions have to meet the requirements of wastewater disposal and discharge of treated water into fishery water bodies. The choice of the wastewater treatment technique for textile enterprises depends on many factors: capacity (flow of wastewater), the possibility and feasibility of extracting impurities from wastewater, the requirements for the quality of treated water when it is reused or discharged. Dimensions of membrane bioreactors afford installation of them in conditions of limited space. Operation of membrane bioreactors may be easily provided by filtered wastewater even at wastewater treatment plants of low capacity, so pure water use is not required. The combined Fenton oxidation and the process of membrane sludge separation as an advanced wastewater treatment with integrated dyeing wastewater treatment plant to reduce total organic carbon and coloration. The system has three steps of treatment: the Fenton oxidation unit, which is an aerated continuous reactor with a mixer, a neutralization tank that equalizes the pH value of the influent and MBR.
