AB The membrane bioreactors are a technology wide-ly applied to wastewater treatment and regeneration.However, its full implementation is hindered by mem-brane fouling, which increases maintenance costs anddecreases productivity. Therefore, the development ofoperation modes that allow the membrane foulingcontrol is fundamental in the implementation of thistechnology. This paper presents a techno-economicanalysis of a process operation mode based on the dy-namic control of the frequency of physical cleaning ofthe membrane, as a function of the fouling achieved.From experimental data obtained in a pilot-scale in-stallation, empirical models were developed to ana-lyze the effect of the operation variables on fouling.The economic analysis allowed to establish the opti-mal operating conditions, which are given to a filtra-tion and backwash flow of 50 and 35 L/h· m 2 , respec-tively, without the need of membrane aeration duringfiltration and ensuring an effective fouling control
