Abstract: Ab α-shape tubular photobioreactor was designed and constructed based on knowledge of algal growth physiology using sunlight. The algal culture is lifted 5 m by air to a receiver tank. From the receiver tank, the culture flows down parallel polyvinyl-chloride tubes of 25 m length and 2.5 cm internal diameter, placed at an angle of 25 ° with the horizontal to reach another set of air riser tubes. Again the culture is lifted 5 m to another receiver tank, then flows down parallel tubes connected to the base of the first set of riser tubes. Thus, the bioreactor system looks like the symbol α. As there is no change in the direction of the liquid flow, high liquid flow rate and Reynolds Number can be achieved at relatively low air flow rate in the riser tubes. Due to the high area-volume ratio of the bioreactor, and equable photosynthetically available radiance and culture temperature, biomass density of exceeding 10 g dry weight L -1 and daily output rate of 72 g dry weight m -2 land d -1 were achieved. © 1995 Kluwer Academic Publishers.
