Membranes separation processes play a crucial role in many separation applications ranging from waste water treatment to drinking water and the filtration of particles in food suspensions [
1]. These membranes are made from synthetic polymer materials of varying compositions. The diversity of their chemical compositions give them excellent properties (rigidity, flexibility or elasticity, mechanical and chemical resistance). This is why their annual production has risen from 1.5 million tonnes in 1950 to more than 350 million tonnes today and it is still growing steadily after use, synthetic polymers are released into the environment causing major environmental problems [

Ingestion of the fragments causes internal injuries or blocks digestion, increasing morbidity and mortality in living creatures. It is estimated worldwide, around half of all sea turtles have ingested these polymers, although the exact proportion is not known [

The small size of microplastics facilitates their passage through gastrointestinal membranes and their distribution in tissues and organs resulting in the induction of oxidative stress, genome instability, disruption of the endocrine system, reproductive abnormalities, embryo toxicity and trans-generational toxicity [

Nowadays, the widespread awareness of ecological and socio-economic imperatives, the search for sustainable green technologies, the growing problem of waste, environmental legislative standards and the depletion of fossil resources have led scientific research to focus on the development of membranes based on natural fibers [

10]. What's more, their molecular structure gives them a high affinity for certain pollutants such as heavy metals, oils and dyes [

12]. But setting up a natural membrane requires prior study as with weaving. Several weaving modes influence the hydrodynamics and efficiency of a natural membrane depending on its nature [
13,

15,
16,
17,
18]. The weaving mode can be twill, satin or plain and the choice of a weaving mode will depend on the hydrodynamic behaviour and filtration performance of the membrane. Hence the interest of this work is to choose the best weave that gives the best hydrodynamic and filtration behaviour for woven membranes from banana pseudo-stem fibers.
