The new offering retains the high heat resistance and permeability needed for these applications with its pore size, or molecular weight cut-off, reduced to around one-quarter that of Toray’s conventional counterparts. This enhances recovery rates and concentration ratios for proteins and polysaccharides with a broader range of molecular weights to streamline processes. The technology also helps reduce carbon dioxide emissions and manufacturing costs.

Toray has drawn on its hollow fiber membrane technology for water treatment to expand its lineup of hollow fiber membrane modules for food, beverage, and biorelated applications. These products feature a unique outside-in module. Wide flow channels for feed liquid enable the concentration and purification of even highly turbid and viscous liquids that are difficult to filter. A proprietary composite hollow fiber membrane structure ensures high permeability and low fouling, with high resistance against steam and hot water up to 125°C.
Toray has started shipping samples to customers, with several conducting assessments. In the future, customers will be able to select hollow fiber membrane modules that are best for their applications and manufacturing processes by using Toray’s new offering to concentrate and purify low-molecular-weight target substances and its conventional products to concentrate and purify high-molecular-weight target substances.
