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
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.
