Prefiltration of wastewater effluent: Effects on foulants and performance during dead end ultrafiltration Original Research Article

An important trend in the development of ultrafiltration (UF) of wastewater effluent is the integration of pretreatment to improve the performance of membranes. In this paper the results of a study on the effect of three prefiltration techniques (multimedia filtration, granulated activated carbon filtration and biological activated carbon filtration) on foulants and performance of UF are presented. The objectives of the study are: (1) to establish the different effect of three prefiltration configurations on performance of UF and foulants of wastewater effluent and (2), to determine in which particle size range the most particles or colloidals are removed after the three prefiltration configurations.
