Asahi Kasei, a Japan-based ammonia and cellulose fibre company, has launched a hollow-fibre membrane system to produce sterile water for injections.
The membrane system was developed as an alternative to the conventional distillation processes for the production of water for injection (WFI).
The Microza, hollow-fiber membrane, is specifically for water treatment and filtration of liquid products
The new system uses Microza (trademarked), a hollow-fibre membrane, specifically for water treatment and filtration of liquid products.
By reducing the need to generate steam, this system enables lower CO2 emissions and lower costs in the production of WFI, contributing to lower energy consumption and improved water quality.
The membrane system
The WFI membrane system is based on steam-sterilisable ultrafiltration (UF) membranes for water treatment that have been widely used in the pharmaceutical industry.
