Direct ultrafiltration with membranes applied to the carbon recovery from municipal wastewater

Abstract

Wastewater treatment plants (WWTPs) are considered with relevant importance for the safe continuity of the water cycle, with a direct impact on the environment and human activities. In this sense, the increasing global demand for sustainable technologies should encourage the urban wastewater treatment sector to improve carbon and nutrient recovery combined with the high quality of treated water. In this context, direct filtration with membranes applied to the recovery of organic material from municipal wastewater, together with the ever-greater robustness and experience of ultrafiltration membranes, appears as a robust, flexible CHAPTER 4 | Membrane-based technologies for the up-concentration of municipal wastewater Membrane-based technologies for the up-concentration of municipal wastewater: a review of pretreatment intensification
