Résumé:
Water is a form of energy which is essential for life and to maintain ecosystems. Nowadays,
the waters in our planet are subject to high pollution levels becoming increasingly scarce. In
this context, the technological advances have put in the market alternative water treatment
processes, for example, the membrane separation processes. Due to the degradation of the
hydric resources, the use of these processes becomes one more treatment option for the
production of good quality water. Ceramic membranes have been gaining space in the market
due to diverse advantages, like long useful life, a cheaper manufacture cost, easy cleaning and
resistance to high temperatures. The purification of water through ionic exchange resins is
called demineralization, this process removes ions present in water, through cationic and
anionic resins. The present work had the aim to analyse the performance of a hybrid system
comprised of ceramic microfiltration membranes packed with ionic exchange resins for water
treatment. The system was evaluated by means of permeate and concentrate flux behaviour
with time, residence time and physical-chemical properties. For the studied operating
pressures (1,0 bar, 2,0 bar, 3,0 bar e 4,0 bar), the permeate flux behaviour varied as a function
of the turbidity of the feed. It was concluded that the operating pressure of 2.0 bar showed less
variation in the permeate flow as function of turbidity of the feed water and for the turbidity
of 3.0 uT and 4.0 uT, this pressure produced more permeate. In addition, the hybrid system
has shown efficient removal of colour, turbidity and chemical parameters for non-salty
waters, producing high quality treated water with a low energy consumption.
