BKT - Model FMX -Anti-Fouling Membrane Filtration Systems
FMX is a new anti-fouling membrane system based on the simple, yet innovative concept of using vortices to prevent fouling of the membrane for high density, high viscosity, and high solid applications.
- A revolutionary membrane filtration system that uses high-speed vortex generation to reduce fouling
- Ideal solution for separation, concentration, recovery, de-watering, reuse, and/or treatment applications
- Successful track record in challenging applications
- A full range of models and membranes (MF, UF or NF) are available to satisfy our clients’ demands
FMX has been used for wastewater treatment, separation and dewatering in manufacturing processes and recovery (reuse, recycle) applications in various industries, such as digestate & livestock waste, food & beverage, biotech, chemical, mining, and oil & energy.
FMX maintains high flux and recovery rate under the most challenging conditions. Optimal Membrane Selection Program (OMSP) allows BKT to select the most suitable membrane based on the characteristics of feed and clients` demands. BKT does not manufacture membranes; instead, BKT adapts various types of membranes (MF, UF, and NF) to be used in FMX.
The membrane module is constructed with flat sheet, vertically stacked membrane trays. The membrane trays are stationary, and are surrounded on each side by vortex generators.
The vortex generators are veined discs which spin at a high RPM and to not come in contact with the membranes. High turbulence keeps solids in suspension and off the membrane surface.
The module is pressurized in order to push clean water through the membranes and into a clean water collection channel.
LIMITATIONS DUE TO MEMBRANE FOULINGMembrane filtration is becoming a popular choice for solid-liquid separation or wastewater treatment. However, industries have realized that membrane filtration technology also has its shortcomings. Fouling is one of the major concerns when membrane filtration technology is considered for wastewater treatment or a manufacturing process. Over time foulants form a boundary layer on the membrane surface, dramatically decreasing the permeate flow rate. This shortcoming often limits conventional membrane filtration systems to low-solid feed streams and requires complicated pre-treatments prior to the membrane filtration systems.
CONVENTIONAL MEMBRANE FILTRATION SYSTEMIn conventional membrane filtration systems, such as spiral-wound, tubular, and plate-and-frame, the feed stream is pumped rapidly across the membrane surface to generate the cross-flow in order to remove the boundary layer built by foulants. However, this method is often ineffective because the shear force is the weakest near the membrane surface. As the membrane continues to foul, the permeate flow decreases and a water flush or chemical cleaning is required. Therefore, conventional membrane filtration systems require low-solid feed streams.
