We offer a range of different ultrafiltration (UF) membrane modules that are perfectly suited for the pretreatment phase in the process of making Purified Water (PW), Highly Purified Water (HPW) or Water For Injection (WFI). X-Flow hollow-fiber UF membranes address total suspended solids, turbidity, bacteria and viruses. The well-known X-Flow membrane modules Xiga and Aquaflex are the industry standard for pretreatment reverse osmosis (RO).
Our hollow-fiber UF membrane modules are available in two configurations:
- Horizontal dead-end: with multiple Xiga elements (up to four) installed in horizontally positionmembrane housings
- Vertical dead-end: with single Aquaflex modules mounted vertically in a skid
Process water treatment
- Alternatively, we offer the X-line rack: a pre-engineered, highly flexible UF concept including end caps with integrated headers
Process water in the pharmaceutical industry is divided into three different grades, with the lowest grade water being purified water (PW), the next is highly purified water (HPW) and water for injection (WFI) is the highest grade.
