slugStudy of Efficacy of Riser and Downcomer Plates as Light Receivers: For microalgae Culture in a Vertical Flat Plate Airlift Photobioreactor
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 7
Abstract
Photobioreactor are considered to have high productivity in a controlled condition for microalgae cultivation. Among different types of photobioreactor, tubular and vertical airlift systems were evaluated to be effective for scale up cultures. Further, limitation arose in scale up of tubular systems are thought to be overcome by using flat plate reactors. Vertical plate system has advantage over tubular system as they could be tilted towards light source or sun, absorbing maximum incident energy. In case of vertical flat plate airlift photobioreactor, as both of its plates (i.e. downcomer and riser plate) could be used as light receiver, it is important to identify effectiveness of these plates for outdoor culture. In our study downcomer plate was found to be better light receiver compared to riser plate as specific growth rate was increased from 0. 332 ± .01 day-1 to 0.514 ± 0.06 day-1.
