CoMeTas CoMex - Cross-flow SiC ceramic membranes with permeate conduits
Silicon Carbide (SiC) ceramic membrane elements utilizing cross-flow filtration principle.
The ceramic membranes are available for MF and UF. The membrane elements show superior flux, filtration properties and energy/construction savings compared to traditional ceramic membranes. An increase of five (5) times the flux of traditional SiC cross-flow membrane elements has been recorded. The membranes are suitable in a vast variety of applications where cross-flow is applied today, i.e. produced water, waste water, industrial processes, ballast water etc. Description including main features/advantages The membrane elements provide high filtration capacity per unit volume. One element (Ų144mm x L865mm with 0,04 micron pore size) yields 23 m3/h permeate flux at 0.2 bar TMP (water at 20◦C). SiC allows for harsh operating conditions: chemically resistant in pH 0-14, temperature resistant +1000◦C and mechanical robust with TMP up to 10 bar. Innovative aspects The ceramic membrane is a further development of existing cross-flow membrane elements. The new improved design with permeate conduits excel with higher energy efficiency compared to traditional cross-flow systems due to higher flux rates, while maintaining the robust filtration properties. The membrane elements are an ideal alternative to traditional cross-flow membranes in existing and new installations. Installed Comex membranes elements will potentially reduce power consumption in membrane installations worldwide. Current and potential industrial users/domains of application The membranes are currently installed at operating sites in Canada (oil sand) and The Netherlands (surface water). Potential industrial fields of application are: Oil and gas, waste water treatment, industrial processes, water supply, etc. Current state of development The membrane elements are manufactured in varying geometries with different pore sizes according to the application. The membrane elements have been tested in-house and externally. The membranes still need to be tested on a number of applications like sea/surface water and industrial waste waters.
