Membrane Photobioreactor as a Culture Device of Microalgae

Membrane photobioreactor is a term that is used to describe a membrane contactor that is integrated with a photobioreactor to enhance CO2 mitigation by microalgae. The membrane module can be externally or internally integrated with the culture vessel of microalgae. The membrane photobioreactor can be considered as a new development in the research field, since it was first mentioned in […]

Design Considerations for a Membrane-Integrated Photobioreactor

The basic feature of a membrane-integrated photobioreactor for CO2 utilization by microalgae culture consists of CO2 supply set, a membrane set, and photobioreactor system. The CO2 supply set consists of an air compressor, gas mixer, gas filter (optional), and a CO2 tank. The membrane set consists of a peristaltic pump and one or more mem­brane contactor modules. The photobioreactor system […]

Analysis and Method to Supply CO2 Through the Membrane Contactor

The most important part of a membrane photobioreactor set up is the connection of the membrane device to the photobioreactor, because it affects the CO2 supply and microalgae productivity. The CO2 gas can be saturated using a water column (Ferreira et al. 1998) or a gas mixer (Cheng et al. 2006; Fan et al. 2007). Each open­ing between the CO2 […]

Cultivation Technique to Improve the CO2 Uptake by Microalgae in the Photobioreactor

A cultivation technique is important because it affects the CO2 utilization and bio­mass productivity of the microalgae. Thus, the choice of a batch, continuous, or semi-continuous mode of culture has a significant effect on the microalgae photosyn­thesis process. A batch culture of microalgae is defined as a culture period, whereas the cultivated microalgae cell is harvested at once. The batch […]
