NEWater Microfiltration Membrane Details：
There are more than ten specifications of microporous membranes, with pore diameters ranging from 14 μm to 0.025 μm, and film thicknesses from 120 to 150 μm. Its effective separation range is 0.1-10μm particles, and the operating static pressure difference is 0.01-0.2MPa.
The materials of microfiltration membranes are divided into two categories: organic and inorganic. Organic polymers include cellulose acetate, polypropylene, polycarbonate, polysulfone, polyamide, etc. Inorganic membrane materials include ceramics and metals, sintered metals (such as stainless steel), alumina, glass, silica, etc. Its operating pressure is around 0.01-0.2MPa.
Microfiltration, also known as micropore filtration, is a precision filtration that can filter micron or nanoscale particles and bacteria. The basic principle is similar to the working principle of ultrafiltration, nanofiltration, and reverse osmosis. The solute and solvent are separated, concentrated, and purified by pressure difference (such as pressure difference, concentration difference, potential difference, etc.).
When there is a certain pressure difference on both sides of the membrane, part of the solvent and components smaller than the membrane pore size can be allowed to pass through the membrane, while particles, macromolecules, salts, etc. are intercepted by the membrane, thereby achieving the purpose of separation.
There are three filtration principles of microfiltration:
(1) Screening: Microporous filter membrane intercepts particles larger than the membrane pore size or equivalent to the membrane pore size, also known as mechanical interception.
(2) Adsorption: The particles are adsorbed by the filter membrane through physical and chemical adsorption. Particles smaller than the membrane pores can also be trapped.
(3) Bridging: The particles pile up and push each other, causing many particles to be unable to enter the membrane pores or get stuck in the pores, thereby completing the interception.
At present, microfiltration membranes have been widely used in the fields of pharmaceutical industry, electronics, biopharmaceuticals, scientific research and quality testing. Common application areas include:
- Cold sterilization of beverages and pharmaceuticals
- Separating bacteria from water
- Liquid pharmaceuticals, and medicines
- Clarifying fruit juices, wine, or beer

NEWater Microfiltration Membrane
Microfiltration is a physical method of water purification. In this method, microfiltration membranes are used to separate the solid particles from feedwater. NEWater microfiltration membranes with isotropic or asymmetrical pore structures have broad-spectrum usages. Besides, they are known for the best chemical and thermal stability. Also, we use advanced surface modification for better hydrophilicity and lesser membrane fouling. However, based on the concentration of solids in the feedwater for a specific application, our MF membranes also may need periodic cleaning and maintenance to resist membrane fouling.
Our MF membranes are usually made of polymers. Polytetrafluoroethylene, polyester, cellulose acetate, polyethersulfone, and polyethylene are some of those polymers. However, we also have microfiltration membranes made of inorganic materials like glass and stainless steel.
Based on the material and technique used, the underlying pore structure and shape differ from one membrane to another. The pores in polymeric membranes are more interconnected, thanks to the isotropic quality of different polymer fibers. Besides, they can perform excellent metal absorption and adsorption. However, the metallic membrane pores are more uniform in structure.
If we talk about membrane filtration, NEWater microfiltration membranes are undoubtedly the most effective. Through a physical process and a size-exclusion principle, our MF membranes will retain larger contaminants, including algae, pathogens, bacteria, sand, clay, metal, and other complex particles. When used in direct flow filtration, these can treat feedwater that has a lesser concentration of particulate solids or where the application demands a purified filtrate for further treatments like RO or wastewater treatment.
Our microfiltration membranes also support crossflow filtration. Here the membranes can treat feedwater with a high concentration of solid particles. Further, in the crossflow filtration, the feedwater passes along the MF membranes’ surface. Also, being a continuous process, crossflow filtration stops the accumulation of solid particles that block the flow of feedwater through the membranes.
Again, these microfiltration membranes are great for water pretreatment, where the treated water further goes through RO or NF purification processes. Our professional team installs the membranes in well-designed systems. Moreover, our MF membranes are available in flat sheet, plate, and frame, hollow fiber, tubular, and spiral wound configurations.
