Klimaschonung durch Membrananwendung – Membrandestillation zur Erzeugung von pharmazeutischem Reinstwasser

Water is the most important medium in the pharmaceutical industry. The required water quality depends on the intended purpose and this in turn influences the effort involved in water treatment. Today, the production of pure water for use in the pharmaceutical industry is mainly based on multistage distillation and membrane processes, especially the combination of reverse osmosis, electrodeionization and ultrafiltration. Membrane distillation (MD) as a relatively new method is an alternative to these classic methods of pure and ultrapure water production. The treatment of pharmaceutical water from drinking water with the help of MD is presented. More specifically, the focus is on the suitability for pharmaceutical water treatment, the effect of different process parameters on the performance, and the possibility to reduce the specific energy demand.
