The scarcity of freshwater in most of the countries in the Mediterranean Basin makes treated
wastewater a valuable alternative water source. The improved technology for the removal of particles,
turbidity, bacteria and cysts from effluent, without the use of disinfectants is based on the use of
membranes, mainly on Micro-Filtration (MF) and Ultra-Filtration (UF). Membrane treatment of
secondary effluent and surface water sounds attractive since it is a stable water source. Pathogens,
soluble organic maters, turbidity, color, parasites and viruses can be removed by membrane technology.
Field data from several research sites related to effluent quality; surface water and back-washed filtrate
provides performance estimate efficiencies based on the Data Envelopment Analysis (DEA)
method. The exploration focused on individual UF and MF experiments determining the
membrane performance efficiency in terms of information quality for adequate decision-making. DEA
is an empirically based methodology and the research approach has been found to be effective in the
depiction and analysis of complex systems efficiency, where a large number of mutual interacting
variables are involved. Includes 33 references, table, figures.
