Membrane filters act as a barrier to separate contaminants from water, or they remove the particles contaminating the water. Reverse osmosis, ultrafiltration, and nanofiltration all use a membrane in their different filtration processes. Our Master Water Specialist, John Woodard, explains what a membrane filter is and how it works inside different water filtration systems.
Membrane Filter Cartridge As you can see, these are simple and modular filters, with a large surface area of filter media that can fit in different housings. They are popular for their low-pressure losses and high flow rates when removing particles from fluids. Ordinarily, this component is designed to suit a specific need in various industries.
If the membrane does not have a substrate, it is bio-directional and either side can be used as the inlet. If it has a substrate, the substrate layer will be more coarse and ridged than the membrane side. The membrane side would be the inlet and the coarse substrate side the outlet. The solvent should enter the inlet side of the membrane first.
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 filters can be installed in compact, automated, or modular units. These strainers can be used as separators
or 0.45 µm membrane filter for fine filtration. This combination of membranes provides significantly greater throughput than standard filters without prefiltration media, especially when filtering particle laden solutions. 50mm Millex® syringe filters have hydrophobic chemistry Related Products: Compare this item
Membrane filters are used to remove both dissolved and particulate inorganic substances. The nature of the substance will determine the level of tightness that is required to remove it. Membrane filters are used to remove organic compounds.

Depth filtration. In terms of particle retention, filters fall into two categories: surface filters and depth filters. Surface filters, generally referred to as membranes, trap particles exclusively on the top surface. These filters are well suited to samples with low particulate content. However, high particulate content tends to rapidly clog
Aug 07, 2018 · Cellulose Acetate (CA) Membrane. Hydrophilic filtration membrane with limited chemical resistance but made from pure cellulose acetate, which is very low protein binding and so excellent for protein recovery. Withstands temperatures up to 180°C, making it well suited for hot gases.

Cellulose nitrate or mixed cellulose ester membrane filters are indicated for many general laboratory applications where a membrane with a high non-specific adsorption is suitable. They are hydrophilic, have high flow rates thanks to their symmetric structure and are compatible with aqueous solutions (pH 4 to 8), hydrocarbons and several other organic solvents.
Membrane Filters Membrane filters are constructed out of a wide range of synthetic materials, including cellulose acetate, cellulose nitrate (collodion), polyamide (nylon), polycarbonate, polypropylene, and polytetrafluoroethylene (Teflon). With the exception of polycarbonate filters, most form a complex network of fine, interconnected channels.
