A major Japanese corporation, Asahi Kasei is the pioneer of PVDF hollow fiber UF membranes and with its original TIPS technology and its unique double skin membrane structure.

Unlike general throw-away membranes, Asahi Kasei Microza™ membranes are highly durable and are designed for long life and small to large scale water treatment plants with designed and operating life from 5 years up to 10 years and even more.

Besides its strong base in its home market Japan, Microza holds the leading share of the US market for membrane-process water clarification systems. Microza has a strong global presence including majority MF/UF market share in Singapore NEWater plants, large scale desalination projects in Middle Eastern countries and major presence in water treatment plants across China.

Scope of Microza (separation targets and fields)

There are two major Microza lineups: ultrafiltration (UF) and microfiltration (MF) membranes. Sieving through the pores on the surfaces of hollow fiber, UF membrane can separate proteins and endotoxins, and MF membrane can be used to separate various microbial cell bodies and protozoa.

Hollow Fiber membrane, Microza

Microza, containing the hollow fiber membrane of Asahi Kasei, is feasible for separation and clarification in a wide range of fields, including electronics, water supply, sewage, industrial water, industrial wastewater, and water recycling,

UN Series

UN series Polyvinylidene difluoride (PVDF) hollow fiber has high mechanical and chemical strengths and has been widely used as a material suitable for MF and UF membranes. Asahi Kasei has over 40 years of experience and results as a pioneer manufacturer of PVDF hollow fiber membranes.

  • Water purification plants
  • Water supply in the industrial complex
  • Reuse of effluent from a sewage-treatment plant
  • Available in submerged modules (UHS series)
  • Treatment of industrial wastewater such as in fields of power generation, steel, paper manufacture, food, petroleum gas, and pharmaceutical industries.

Microza UF VIP and SIP Series

These series are used in pharmaceutical and food production processes and have been widely used for the concentration and purification of enzymes, proteins, and food ingredients. To be used for these purposes, a sanitary housing structure is employed. The lineup covers a wide range of fractions.  

  • Meeting USP-Class VI requirement (SIP series)
  • large membrane area per unit volume, high water permeability
  • The double-skin filter structure ensures reliable endotoxin removal
  • Fields of pharmacy and medical equipment
  • High hot water sanitizing and steam sterilization options
Microza UF AV and SW series
Microza UF AP and SP Series

These series are used mainly in the field of chemical industry and have been widely installed in purification and concentration processes of fine powder products of nanomaterials, fine ceramics, metallic oxides, and all-purpose inorganic materials as well as others. They are also used for recycling inorganic and organic wastewater from chemical factories, contributing to environmental protection.
