Apparatus and method for biological purification of waste

An apparatus for delivering a pre-conditioned bacterial culture to an environment containing wastes including wastes which are substrates for metabolism of the bacterial culture, the apparatus comprising:

• a) a first container having a bioreactor chamber containing a bacterial culture;
• b) a second container having a second chamber containing an aqueous solution containing inorganic nutrients;
• c) a third container having a third chamber containing a supply of organic nutrients which are soluble in an aqueous solution, the third chamber being operably connected in one-way fluid communication between the bioreactor chamber and the second chamber;
• d) a controller comprising:
• i) means for introducing a predetermined supply of aqueous solution from the second chamber to the third chamber and from the third chamber to the bioreactor chamber;
• ii) means for removing a predetermined volume of bacterial culture from the bioreactor chamber thereby enabling maintenance of the bacterial culture in substantially exponential growth in the bioreactor chamber;
• and
• iii) means for delivering the predetermined supply of bacterial culture from the bioreactor chamber to the environment containing wastes including wastes which are substrates for metabolism of the bacterial culture.
