Advanced Treatment of Wastewater from UASB Reactor by Microfiltration Membrane Associated With Disinfection by Ultraviolet Radiation
The low efficiency of UASB bioreactors, regarding the removal of nutrient, organic matter and pathogens, makes it necessary to carry out a post treatment, in order to improve the quality of the effluent. Accordingly, this research has examined the use of microfiltration associated to the disinfectio...
