Problem Statement
Using Aquaponic Towers such as in the Aquaponic Greenhouse - how many of these towers - functioning as worm towers - would be required to process household blackwater?
Chemical Oxygen Demand per day per person is 100g - from Biodigester#Technical_Design_.2B_Calculations. About 1 lb wet feces per day.
Feces is 75% water. [1]. It requires only 100 Whr to evaporate the water in feces. But, feces will be in a larger volume of water, such as 1 gallon - making it 0.6 kWhr for evaporation. Not bad. This would be an incinerating toilet.
For worms - vermiposting works at approximately 1kg worm biomass per 1 kg feedstock per day - [2].
