Project Background

This feasibility study was focused on algae harvesting with submerged IPC® membranes as a pre-concentration step prior to centrifugation.

The use of backwashing as fouling control was compared to standard relaxation with other flat panel membranes. The PVDF IPC® ultrafiltration membranes showed better fouling resistance showing that the back washable IPC® membranes achieved up to 300% higher fluxes compared to commercial benchmark.

The energy consumption for membrane filtration followed by centrifugation was estimated at 0.17 kWh/kg of dry weight of algae when IPC® technology was used compared to 0.5 kWh/kg for algae harvesting via centrifugation.

Integrated Permeate Channel (IPCÒ) membrane modules

The IPC® membrane modules are flat sheet membrane modules, which are constructed by many parallel-arranged membrane envelopes with defined distances between these envelopes. The individual envelopes are comprised of a 3D spacer fabric and coated with a PVDF ultrafiltration (UF) membrane which is anchored within the spacer. This anchoring allows for the unique high pressure backwash of the IPC® membranes. As a result, these membranes are operated at a much higher flux rates than other flat panel submerged membranes. The full-scale membrane bioreactor system delivers a higher capacity per footprint at a significantly lower operational expense compared to competitors.
