In 1968, Toray began the investigation of membrane water treatment technologies and has developed many types of membrane to separate the impurities in different sizes for the perfect water purification. Toray is currently one of the leading companies in the world. The hollow fiber membrane applied to water purifiers Torayvino was developed based on medical technology, used for artificial kidneys. The reduction of bacteria is compliant to the Japan Wind Power Association (JWPA) of voluntary standards for water purification. The water purifier has been proven to remove 99.99% of bacteria as defined in the standards.

TORAYVINO® Household Water Purifiers were developed based on our filtering technology used for medical devices. They feature sophisticated filtration media such as hollow fiber membrane filters as well as superior resins and other technologically advanced media. First launched in 1986, TORAYVINO® filters have now become the most famous* water purifiers in Japan. At Toray, we are working each day to develop TORAYVINO® products that will offer even better performance, functionality, and design to the consumers.

Hollow fiber modules have an advantage of removing bacteria and turbidity with low pressure. By combining with the activated carbon, it can form a well-balanced household water purifier.

Hollow fiber is an ultrafiltration technology utilizing a membrane separation process that allows removal of suspended solids including particles, colloids, cysts, bacteria and viruses. UF membranes remove suspended solids based on pore size. Hollow fiber membranes are formed in hollow fibers and configured in modules containing multiple fibers.

The hollow fiber membrane traps very fine particulates, and permits accumulated material to be flushed away periodically. This eliminates frequent course pre-filter changes and the flushing mechanism restores like-new filter operation and performance.

Hollow fiber ultrafiltration can be used for many applications requiring the removal of suspended solids including particles, colloids, cysts, bacteria and viruses.
