Aquious - PCI manufactures open-channel tubular polymeric membranes, and several different types of module housing into which they fit. In addition, we supply spiral-wound membranes and their pressure vessels.

Membranes are available for Microfiltration* (MF), Ultrafiltration (UF), Nanofiltration (NF) and Reverse Omosis (RO). The various modules and the types of membrane available for each are shown below.

*Microfiltration Open UF membranes in Aquious' tubular membrane range are often found to give suitable performance at the tighter end of what  might normally be considered classic microfiltration duties, and can be a more economic solution than ceramic (MF).

Spiral Modules

Aquious - PCI also supplies a wide range of spiral-wound membranes for applications with low levels of suspended solids in the dairy, food, pharmaceutical and chemical markets. They are available in a range of sizes, and with different housings to suit sanitary and non-sanitary applications.

Test Modules

Aquious - PCI supplies test modules with small membrane area to allow pilot scale trials to be conducted to develop design information. Three different devices are available for tubular membranes, the “Single-tube-Tester” and the “MIC-RO 240” which are both used for testing 12.5mm diameter membranes and the “A5 Mini Module” which is used for testing 6mm diameter membranes. Small spiral membrane elements are also available.

Membrane Development

Where it may be economically viable, our specialist membrane research and development team is able to work closely with our customers to modify an existing commercial membrane, or to produce a new membrane, should the commercial range fail to solve a particular problem.

New membranes have been developed and site tested in less than 3 months. This can prove highly beneficial where short process development times are the key to commercial success.

New developments include hydrophylic membranes for lower fouling, improved selectivity, increased solvent, acid and base resistance, and strengthened.
