PBR type | Cyanobacterial species used | Advantage | Disadvantage | References |
---|---|---|---|---|
Vertical Column | Spirulina platensi | 1. Simple and cost effective design 2. Greater rate of mass transfer in bubble columns | 1. Lack of control on irradiant light. 2. Wide fluctuations in productivity. | 57, 58, 64 |
Flat Pannel | Spirulina platensi | 1. Greater control of incident light. 2. Effective control of gas pressure. | 1. Cost for production is high. 2. Complicated design and more maintenance | 59, 61 |
Tubular | Arthrospira platensis, Anabaena variabilis PK84, Anabaena variabilis ATCC 29413, Anabaena variabilis PK84 | 1. Flexibility in volume to surface area ratio. 2. Flexibility in shifting the place receiving light. 3. Give higher biomass with internal static mixture. | 1. While provides flexibility to irradiant light but creates pockets of poor mass transfer 2. Mixing time is longer in internal static mixture TPBR | 42, 60, 61, 63, 65, 66 |
