eclaimed municipal wastewater is becoming a source of public water supplies in places where water is limited. In countries such as Japan, South Africa, and France, legislation encouraging innovative technologies that render wastewater fit for reuse has stimulated the development of alternative processes.1 The use of membranes in tertiary treatment and advanced purification evolved as a promisin...
Textile waste water treatment for industrial reuse remains as a complicated problem due to several reasons. Among them are: 1) Higher levels of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Dissolved Solids (TDS) content of the waste water; 2) Non-biodegradable nature of organic dye stuffs present in the effluent. Thus, any adopted treatment system, especially with resp...
A 162-day pilot-scale operation for reclamation of urban wastewater was studied by using an ultrafiltration membrane bioreactor (UMBR). Performance of the UMBR was investigated with a sludge retention time (SRT) of 5, 15, and 30 days, a hydraulic retention time (HRT) of 5 h, and membrane flux between 75 and 150 l m−2 h−1, respectively. It was observed that the highest sludge concentration in th...
An electrochemical membrane bioreactor (EMBR) has recently been developed for energy recovery and wastewater treatment. The hydrodynamics of the EMBR would significantly affect the mass transfers and reaction kinetics, exerting a pronounced effect on reactor performance. However, only scarce information is available to date. In this study, the hydrodynamic characteristics of the EMBR were inves...
