Production of Desalination Membranes From Recycled PVDF Polymers

<p class="RsumText" style="text-indent:0cm"><span lang="TR">Water is not only an essential resource for life but alsoa crucial input in industry. Water sources around the world vary in theirlevels of pollution and salinity. Advanced technologies have been developed forthe use of water in industrial applications. The aim of this study is toinvestigate the separation of saline water using an innovative membranedistillation method for use in process and cooling water. A key point of thestudy is the use of a membrane regenerated from waste polymer in the membranedistillation system. This will ensure waste disposal by reusing waste withoutmixing it into nature, and will contribute to the country's economy byrecycling waste instead of using a new product. In addition, the study willinvolve the direct use of real seawater on an industrial scale.<o:p></o:p></span> <p class="RsumText" style="text-indent:0cm"><span lang="TR">&nbsp;</span> <p class="RsumText" style="text-indent:0cm"><span lang="TR">Within the scope of the study, polyvinylidene fluoride(PVDF), a commercial membrane material, was obtained from waste membranes andreused. This enabled the production of a recycled domestic membrane. The recoveredPVDF was produced as a porous membrane using the electrospinning technique.Characterization tests such as FTIR, porosity-water retention, and mechanicalstrength were performed on the membrane. The porosity value of 78% isconsistent with the structure reported in the literature for recycled PVDF. Thestress value of the membrane obtained using recycled PVDF polymer was measuredas 10.09 MPa, while the strain value was 0.64. This indicates that the membraneexhibits flexible mechanical behavior. Finally, salt rejection of 99% and abovewas achieved.<o:p></o:p></span>
