Abstract
The membrane is a layer formed from fine fibers are used as a filter. In this research, measured the tensile strength and pore size of the membrane that is made in three variations of a specimen with a mixed composition of different Polyvinilidene Fluoride 17.5%, 20%, 22.5%., membrane made using Polyvinilidene Fluoride polimer granules andN,N-Dimethylformamideas solvent and silver nitrate. Membrane molded into standardized test specimens and tested with a device Adhesion Tearring Strength Tester. The results show an increase in the value of the tensile test of 404.8356 KPa to the composition of 17.5%, 507.3598 KPa for composition of 20% and 603.7218 KPa to a composition of 22.5%. For testing the microstructure using a Scanning Electron Microscopy with the resulting increase in pore diameter, for the range of 558.4 nm-781.8 nm are void to the composition of 17.5%, range 670.1 nm - 781.8 nm without voids for the composition of 20% and 1.117 μm-1.228μm without voids on a composition of 22.5
Highlights
Microbiological contamination of some water sources that exist at the moment is very worrying to the public, according to some researchers, there are many different species of bacteria which are available in pure water and wastewater [1,2]
Membrane Polymer produced using Polyvinilidene Fluoride as fiber polymer and DMF as a solvent, the process of printing the membrane by the method of a flat sheet, the membrane of this type is typically used in ultrafiltration process, due to higher porosity and pore structure are interconnected, resulting in permeability is higher for water filtration [4]. be used to determine the characteristics of the membrane there are a number of ways, but a commonused permeability and permeselectivity
The test results of the research shows the mechanical properties of the material Polyvinilidene Fluoride (PVDF) membrane material, each specimen using a membrane tensile testing machine tearing Adhesion strength test
Summary
Microbiological contamination of some water sources that exist at the moment is very worrying to the public, according to some researchers, there are many different species of bacteria which are available in pure water and wastewater [1,2]. This application requires a membrane that can improve water quality. The main objective to be achieved in this discussionare to develop a new method in the production of membran,andTo determine the mechanical properties of the membran of Polyvinilidene Fluoride (PVDF) against tensile testing. Membrane Polymer produced using Polyvinilidene Fluoride as fiber polymer and DMF as a solvent, the process of printing the membrane by the method of a flat sheet, the membrane of this type is typically used in ultrafiltration process, due to higher porosity and pore structure are interconnected, resulting in permeability is higher for water filtration [4]. be used to determine the characteristics of the membrane there are a number of ways, but a commonused permeability and permeselectivity
