to 90 °C sulfuric acid, and evaluated the effect of the pulsation on efficiency of 5 nm-rated PTFE membrane filters in the chemical. in water. Get Price Water Treatment Hydrophilic Ptfe Membrane Strong Acid 0.45um
PTFE membrane hydrophilic can also be used with compatible non-aqueous fluids. Vacuum membrane filter 0.45 μm is usually not used for air, gas, or exhaust filtration because if they get wet accidentally, for example through condensation, the filter will block the flow.
PTFE microfiltration membrane pore size range: 0.03μm-5μm, high precision, large flow, including hydrophilicity and hydrophobicity, strong chemical compatibility and mechanical properties, high temperature resistance. Divided into unsupported material, PP support material, or PET support material, special specifications can be customized
PTFE membrane filters are naturally hydrophobic with excellent chemical resistance, making them the ideal choice for sterile venting of gases*, non-aqueous solvents, acids, and aggressive fluids. Thin, highly porous membrane filter. Behaves as an absolute retentive membrane. Inert to most agressive solvents, including strong acids and bases.
GGPTFE-Series High Purity General Grade PTFE Filter Cartridges, with expanded polytetrafluoroethylene (PTFE) membrane, provide superior chemical resistance for a broad range of industrial applications. With retention ratings as fine as 0.1μ (100 nanometers), consistent contaminant removal is achieved in aggressive fluids and organic solvents.
PTFE (Polytetrafluorethylene). The hydrophobic nature of teflon and its broad chemical compatibility make it the filter of choice for filtration of air and gases, for use as vents and for clarification of acids, bases and solvents. The teflon membrane needs to be prewet with alcohol before aqueous solutions can be filtered.
Dec 05, 2018 · The polytetrafluoroethylene (PTFE) membrane is an inlet membrane, a hydrophobic membrane filter, which is treated with ethanol or isopropanol to become a hydrophilic membrane filter. The hydrophobic membrane cannot be naturally wetted, and the hydrophilic membrane can be naturally wetted. Polytetrafluoroethylene (PTFE) membranes are resistant
Our unsupported, hydrophobic, PTFE membrane filters are ideal for sterilization and venting applications involving air, gasses, and solvents/acids incompatible with most other filters. These PTFE filters are chemically and biologically inert, stable up to 260°C, and will withstand the majority of concentrated acids and bases and are especially
PTFEteflon membrane has strong acid and alkali resistance, chemical corrosion resistance, and unique support layer technology. It has strong anti-shake and anti-scouring capabilities. The normal service life is 8-10 years, which is the service life of general PVDF membranes. 2-4 times. Large water production flux.

Next generation of universal hydrophilic PTFE membrane with maximum chemical compatibility when filtering both aqueous solutions and aggressive solvents.Membrane filters serve as effective physical barriers that remove solids, viruses, bacteria, and other unwanted molecules. Specialized types are designed for softening, disinfecting, organic removal processing, and water desalination. The
Feb 06, 2021 · What are the membrane types in ultrafiltration water treatment? Polymer: These membranes are made from polymer materials such as polysulfone, propylene, cellulose acetate, and polylactic acid. Polymer membranes are more commonly used because of their efficiency and cost-effectiveness. Ceramic: There are various types of materials for ceramic membranes, from aluminum oxide and silicon
The membrane is laminated onto a nonwoven polypropylene support web for improved strength and handling and can be used at temperatures up to 120ºC. Chemically stable and inert: PTFE is the membrane of choice for use with aggressive solvents, liquids, and gases that can attack other membranes. It is resistant to most acids, alkalis, and
