My PhD project was about decentralised anaerobic digestion of wastewater and food scraps.
Lights, camera and action, its time to turn things on and anaerobically digest wastewater and food scraps to make some methane and some recycled effluent.
Once the external plumbing and power was all fixed in things were ready to rock and roll.
You never realise how emotionally tied into a project you are until you see it hanging from four ‘flimsy’ chains underneath a crane.
This is the stairway to the roof of the shipping container. The continuous gas hot water system and the mains electrical control box were on the roof.
The system was very brightly coloured with wires everywhere. Once the insulation was sprayed on the assaul of colours was greatly reduced.
There was quite a complex system of reticulation to supply influent to the two reactors. I ‘built’ the entire system in 3D in AutoCAD first so as to ensure that I could fit everything into this rather tight space.
Here Rob Smith, a wonderful electrician from the Nambour (QLD) area is installing the wiring for the 240V supply. If you are in the Sunshine Coast, I highly recommend Rob. You can contact him here. Email firstname.lastname@example.org
This is looking into the membrane bioreactor. You can see the membrane cassettes at the bottom of the tank. The aeration was pumped in below the cassettes to provide agitation to scrub them.
This shot looks down into the bath and tube heat exchanger. The clean heated water would be in the bath and the wastewater was pumped through the tubes.
