Harvesting algal biomass for biofuels using ultrafiltration membranes.
TL;DR: The results showed that the buildup of the algal cake layer and adsorption of algogenic organic matter (AOM) on the membrane caused membrane fouling, and anti-fouling strategies were established, such as using air-assisted backwash with air scouring, and optimizing operational conditions.
