Hollow fiber membrane module (Large type)

Since cellulose acetate, which is a membrane material with excellent hydrophilicity, is used for FW50 / FZ50 / FN20, their surface are resistant to dirt, and it is possible to maintain high permeability in a stable manner. This membrane module is used not only for water purification, but also for recycling waste water, and it is the module which currently attracts attention the most.

Characteristics of the hollow fiber membrane module (Large type)

Cellulose acetate is used.
Since cellulose acetate, which has high hydrophilicity, is used as the membrane material, it is possible to stabilize the permeability at a high level. Cellulose acetate is composed of acetic acid and cellulose, which is a natural substance, it is a environment-friendly, biodegradable material.

Water supply membrane module standard accredited product
The UF membrane manufactured at our factory is used. Since "FZ50" receives water supply membrane module standard accreditation, it is possible to use at water purification plants.

Pursuit of cost reduction (FN20)
Especially, it is possible to separate the hollow fiber membrane from the housing as a cartridge on "FN20". Therefore, it is possible to reduce wastes at the time of maintenance.

Purpose of use

Water purification systems of water purification plants, RO pretreatment of waste water, ground water utilization systems
