Membrane Microfiltration
Today, many companies depend on microfiltration systems to ensure optimum removal of bacteria and other particles from fluids. Different industries demand different sizes of pores in the membranes to ensure effective performance. Companies can acquire M.W. Watermark™/Porex® Tubular Membrane Modules™ for new and existing filtration systems.
How Membrane Microfiltration Works
Membrane microfiltration is a low-pressure separation process that uses membranes featuring pore sizes ranging from 0.03 to 10 microns. It is used in solvent recovery, water treatment and gas separation. The process is efficient for separating solids such as colloids, fat, particulates and bacteria while allowing the penetration of salt, sugar and proteins.
The most significant use is the treatment of aqueous solutions such as drinking water and beverages. Microfiltration filters can be made from polymer-based membranes, stainless steel or ceramic.

How M.W. Watermark™/Porex® Modules Perform
With our M.W. Watermark™/Porex® Tubular Membrane Modules™, you can enjoy consistent and reliable separations from your water filtration equipment. When fluid flows through the modules at high velocity, the turbulent flow of the stream prevents the buildup of particles on the inner surface of the tube, prolonging the life of your filter.
The performance and large bore tubular design should handle high solids levels up to 5% weight by volume. We offer three distinct tubular membrane models to cater to your specific needs—TMF4, 10 and 37.

The Longevity of M.W. Watermark™/Porex® Modules
With M.W. Watermark™/Porex® Tubular Membrane Modules™, companies are certain to enjoy longer service life and require less cleaning. The modules are made from durable and sturdy material that withstands higher operating and backwash pressures to ensure a greater flux and decreased system footprint. Both the sintered PE and PVDF substrates have PVDF membranes to ensure maximum performance and enhanced chemical compatibility.
The PVDF/PVDF composite option boasts increased abrasion resistance to ensure durability. The uniform omnidirectional substrate pore structure provides maximum support for your tubular membranes. With two internal tube diameters, you are sure to enjoy convenience for your flux and solids separations.
