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.
Using Kuraray’s new membrane production technology, FG module shows three times higher permeability than Kuraray’s existing products.
Kuraray’s proprietary hydrophilized polyvinylidene fluoride (PVDF) membranes are extremely durable.
Due to its one end free structure with a center distributor, FG module can handle raw water with high turbidity.
Adoption of the air backwash method enables operation with a high raw water recovery rate.
Does not require the use of tanks for backwashing or pumping, helping to reduce equipment costs
Products are made of PVDF and polysulfone (PSF) as raw materials.

Notes:
1. Hydrophilized by mixing PVDF (polyvinylidene fluoride) and hydrophilic resin.
2. Hydrophilic treatment coated with PVA (polyvinyl alcohol).
3. Hot water treatment at 90℃ (less than 10 minutes, operating pressure @ 0.1MPa or less) is possible.
