The design of PBR must have the following parameters. 1. Larger surface area to grow. 2. Closed PBR to prevent contamination 3. Proper supply of co2 4. Enough nutrients for algae 5. Ph regulation 6. Temperature maintenance 7. Even sunlight 8. Horizontal design 9. polyethylene bags 10.Automated flow system The closed PBR has many advantages than open PBR. 1.Less contamination in closed PBR 2.Monoculture cultivation 3.Ph, temperature & co2 are maintained easily 4.Prevents water evaporation 5.lower carbon dioxide losses 6.Higher cell concentration 7.Less water supply |
