Sales format
Module, element

Hollow fiber membranes that enable a variety of water treatments

Kuraray’s hollow fiber water treatment membranes are used for water treatment in the industrial, water supply and medical fields.
These products enable precise and efficient filtration in a wide range of settings, including manufacturing of ultra-pure water, drinking water and sterile water, and recovery of process water and wastewater.

Applications

Water purification, ultra-pure water production, pure water recovery, process water/wastewater recovery, sterile (pyrogen-free) water for hospitals/ pharmaceuticals/foods, refining and fermentation of foods, medicines and other products

Characteristics

High permeability

Using Kuraray’s new membrane production technology, FG module shows three times higher permeability than Kuraray’s existing products.

High strength, high chemical resistance

Kuraray’s proprietary hydrophilized polyvinylidene fluoride (PVDF) membranes are extremely durable.

Applicable to high-turbidity water

Due to its one end free structure with a center distributor, FG module can handle raw water with high turbidity.

High raw water recovery rate

Adoption of the air backwash method enables operation with a high raw water recovery rate.

Compact design and reduced costs

Does not require the use of tanks for backwashing or pumping, helping to reduce equipment costs

Extensive product lineup

Products are made of PVDF and polysulfone (PSF) as raw materials.
