What bacteria is used to purify water?

BioVolt uses strains of Geobacter and another microbe called Shewanella oneidensis to process the sludge. Its proprietary mix of organisms has one key advantage – the bacteria liberate some electrons as they respire, effectively turning the whole set-up into a battery.

What bacteria can purify water?

Purifying bacteria, protozoa, and rotifers must either be mixed throughout the water or have the water circulated past them to be effective.

The range of protozoan species found is very wide but may include species of the following genera:

  • Arcella.
  • Blepharisma.
  • Didinium.
