Re: [DIYbio] Biofilter

I'm a little confused on the idea of adding bacteria to produce clean water.

It's sort of like mixing our urine and feces with a bunch of water, so we can then try to purify the water from the waste. Common practice, but not necessarily the best possible solution.

Everyone here has had some great ideas and input, but I think the solution lies at the beginning of your problem - what exactly are you trying to remove, and can you do that in an aerobic environment.

Koi pond operators often build sand filters where the top layer is a bacterial mat.  They need constant flow, or at least
surges every so often to keep that ecosystem happy.  It's not ready to drink though -- you'd need further treatment for
heavy metals, something to take out smells, algae zones to oxygenate and have a different set of bacteria in that stage...

And to be safe it would have to have many stages in series with a big delay, and testing along the way for pathogens,
parasitic creatures, and making sure conditions are always wrong for bad bugs to grow, since it is all live ecosystems
working for you.  Seems like a good life goal -- no quick answers here.

[DIYbio] Legalities of GMO producing biolabs in the EU?

Is there a licensing process required in the EU for creating a biolab where microorganisms are genetically modified and fermented and what is this process like? I'm interested in starting such a laboratory.
