Apparatus 101 for producing a continuous stream of biohydrogen includes a continuous flow stirred tank reactor (CSTR) 12, lighting arrangement 13; ports 14; peristaltic pumps 16; and gas chromatograph (GC) 18. The CSTR 12 includes internal bioreactor chamber 20; a photosynthesizing microorganism inlet stream 22.1 for delivering Chlorella vulgaris; an organic waste inlet stream 22.2 for delivering wastewater activated sludge (WWAS); and a nutrient inlet stream 22.3 for delivering nutrients into the chamber 20; an outlet stream 24; and stirrers for stirring the contents of the chamber. The lighting 13 is provided by lamps 26 for transmitting light through a transparent sidewall of the chamber 20. The ports 14 and CG 18 are for taking measurements from the chamber 20. The pumps 16 control flowrate of the streams 22.1, 22.2, 22.3 and 24 for regulating biohydrogen production from fermentation while Chlorella vulgaris consumes oxygen to avoid biohydrogen conversion into methane.
An apparatus for producing a stream of biohydrogen, the apparatus including:
The apparatus as claimed in 10, wherein the fluid flow controlling means is operable for controlling one or more of the hydraulic retention time;
The apparatus as claimed in 11, wherein the photosynthesizing microorganism inlet stream controller;
The apparatus as claimed in 1, wherein the lighting means is provided by a light transmittable sidewall defining the bioreactor chamber, and through which light may enter the bioreactor chamber.
The apparatus as claimed in 13, wherein the lighting means further includes one or more light source arranged for transmitting light via the light transmittable sidewall into the interior of the bioreactor chamber.
The apparatus as claimed in 14, wherein said one or more light source is in the form of a lamp.
