KMS Hollow Fiber Filtration Technology - Setting New Standards In The Field

KMS hollow fiber membranes have been successfully employed in a wide variety of industries including food, juice, pharmaceutical, metalworking, dairy, wine and most recently municipal drinking water. Depending on the application, hollow fiber membranes can be highly practical and cost effective alternatives to conventional chemical and physical separation processes.

Hollow fiber membranes offer the unique benefits of high membrane packing densities, sanitary designs and, due to their structural integrity and construction, can withstand permeate back pressure thus allowing flexibility in system design and operation.

The hollow fiber geometry allows a high membrane surface area to be contained in a compact module. This means large volumes can be filtered, while utilizing minimal space, with low power consumption. Hollow fiber membranes can be designed for circulation, dead-end, and single-pass operations.

KMS hollow fiber microfiltration and ultrafiltration membranes have become the filtration method of choice for a wide variety of applications. Some of the many hollow fiber membrane filtration applications include:
•  Potable water treatment
•  Juice clarification
•  Citrus juice upgrading
•  Vinegar clarification
•  Wine filtration
•  Dairy processing
•  Oily wastewater minimization
•  Pharmaceutical drug processing
•  Fermentation broth clarification 


Standard and customized KMS solutions to fit your specific needs are readily available. KMS products will:
•  Reduce Space Requirements
•  Decrease Labor Costs
•  Lower Chemical Costs
•  Reduce Waste Disposal
•  Deliver Higher Quality Product Water 



KMS provides a wide selection of hollow fiber membrane products to serve a variety of industrial and municipal applications. Most KMS hollow fiber products are available in:
•  1" diameter laboratory test cartridges ranging up to 10" diameter for commercial products
•  Standard commercial cartridge lengths of 25", 43", 48", 60" and 72"
•  Nominal separation ranges from 0.2 micron down to 1,000 MWCO
•  Fiber inside diameters from 0.02"(.5mm) up to 0.106"(2.7mm)
•  Various materials of construction including polysulfone and PAN
•  NSF 61 certified products for potable drinking water applications
•  Membrane housings with either industrial or sanitary connections

Note: Not all products are available in every configuration, fiber diameter, length, etc.

Hollow Fiber membrane cartridges come in a variety of standard diameters and lengths:
Standard commercial cartridge diameters are 3", 5", 8" and 10"
Standard commercial cartridge lengths are 25", 43", 48", 60" and 72"

KMS hollow fiber cartridges operate from the inside to the outside during filtration. This means that process fluid (retentate) flows through the center of the hollow fiber and permeate passes through the fiber wall to the outside of the membrane fiber. Tangential flow can help limit membrane fouling. Other operating techniques that can be employed with hollow fiber membrane systems include back flushing with permeate and retentate reverse flow. Contact KMS and let us help you design the your next HF membrane system.

Benefits of Hollow Fiber Membranes (inside to outside permeate flow direction)
•  Affords controlled flow hydraulics
•  Tangential flow along the
   membrane surface limits membrane
   fouling
•  Open process flow channel which
   results in less fouling 
•  Physical membrane barrier that
   provides consistent permeate quality
•  Membranes can be backflushed to
   remove solids from the membrane inside
   surface, thus extending the time between
   chemical cleaning cycles
•  High membrane packing density resulting
   in systems with small footprint 
•  Modular system designs can allow for easy
   future expansion

KMS can help you evaluate your specific application requirements and determine if hollow fiber membranes are the best choice for your fluid separation needs. KMS can also enable existing hollow fiber membrane users to enhance the performance and extend the life of their membranes by improving system operating, cleaning and maintenance procedures.
