Better PBR 10

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

    You are right, but the way to go is artificial light. Can be viewed on my website www.algalsolution.com

    Nice article Kumar.
    Am impressed with your profile.
    We are seemingly on the same page.
    I know nothing about PBRs. But i think there is a terrific opportunity to manufacture and sell in India, Europe, usa and australia.
    What is the chepest pbr you can think of !!

    The greatest advantage of using closed PBR's is that the incoming water can easily be sterilized. It follows that if the inoculum is axenic a monoculture is maintained.

    Regarding cost, a lot depends on what level of automation you desire.

    algalsolution.com we can use artificial light. But, it again consumes cost. So i am preferring controlled sunlight.

    reply to manohar: We have to use Polyrthylene bags with customized designs and materials. This could be cheap and degradable.

    Reply for mahesh: The algae has to be genetically re-engineered. The it has high immunity, high lipid content etc.,

    algalsolution.com has nice pbrs. I wish them for their success. But they have to think again about the artificial light. Again i am insisting pls try to avoid vertical designs. Horizontal will provide you more yield than vertical designs. It is experimentally proved.

    It has been about 1-1/2 years since the last posting about the horizontal PBR and low cost algae manufacturing. Has anyone drawn a conclusion on this? Is there now something new and improved? What is the latest and greatest?
