Algae cultivation Using Flue gas

[phyco]

Hi,
Your question may need another research program similar to ASP to answer...We actually can calculate the rate of bioaccumulation of a specific species of algae say chlorella to a specific heavy metal. So you better choose your algae first , Some algae accumulate metals slowly and continuously but some algae accumulate metals for the first few days only.

The rate of bioaccumulation varies with the type of algae and metals...

bye,

I actually trying to figure out the possibility of growing algae and at the same time bio leaching the heavy metals using bacteria. Is it possible to remove the heavy metals using bacteria before they gets accumulated in algal cells?

Any research attempts made to solve this?

If we add both algae and bacteria to sewage at the same time... what happens to the heavy metals? are they removed by bacteria? or Will they bioaccumulate in algae? Or both happens?

You guys have any idea about the rate of bio-accumulation of heavy metals in algal cells..

Bioaccumulation rate differs widely and depend on the strain/species used. The next thing you should not is the heavy metal profile - which metals exactly and if they are toxic for the chosen strain. There are a lot of scientific articles about this topic, unfortunately you have to double check it in your own experiment, before using it.

In Pond Harvesting, How much CO2 escapes to the atm when you pipe up the flue gas from a power plant and bubble it through ponds? That is how much of it is actually captured and how much carbon escapes.

Cat Crackers have finned pipes that cool down from 1300 F. Cooling occurs fairly quickly short runs of pipe to get it to a safe temperatures for operators working within the units. At really hot temps, it radiates more than you would think.

I would envision a long interconnecting piping run to get to the harvesting facility. Uninsulated pipe will cool to ambient in 1000 to 2000 ft, if it is a large pipe, say 16" - 24".
