The Liquid Waste Processing Module
The latest version of the Liquid Disinfection Module is more compact and semi-automated. Solenoid valves and level detection switches control the flow of liquid from collection to process to holding tanks.
The liquid waste processing module uses electrodes to convert the natural salts found in urine into oxidants such as chlorine. The electrochemically generated oxidants disinfect the liquid by destroying the pathogens that come from mixing with the solid waste. The electrochemical process also breaks down the organics in the liquid as demonstrated in this video by the change in color during processing, using a green food coloring dye in a simulated urine solution.
Dr. Ethan Klem demonstrates the electrochemical disinfection module designed for manual control. The heat from combustion is used to dry the human feces applied to the cast-iron automated rotating plate inside the dryer apparatus.
