It might be tricky to make a biofilter that will generally purify all pollutants/toxins/infectious agents from water, but there is definitely work to use biofilters to remove particular pollutants or toxins. I'm sure there are many others, but one group (Larry Wackett's group) I've worked with has done quite a bit in this direction.
A couple of their papers.
Using encapsulated bacteria to break down hydrocarbons: here
Using encapsulated bacteria to break down cyanuric acid (a pollutant that builds up in pools) here

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.-SG--On Sat, Feb 17, 2018 at 7:41 AM John Griessen <john@industromatic.com> wrote:On 02/16/2018 05:05 AM, Fatima wrote:

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.
