Modular system for waste treatment, water recycling, and resource recovery in a space environment

A modular system for waste treatment, water recycling, and resource recovery, the modular system comprising:

• a buffer tank configured to receive and pre-treat raw organic waste, the raw organic waste comprising at least one of solid fecal waste, complex polymers, carbohydrates, proteins, and fats;
• a first reactor tank configured to facilitate at least one of hydrolysis, acidogenesis, and acetogenesis to form organic acids and alcohols;
• a second reactor tank configured as an anaerobic digester that receives digested waste from the first reactor tank, wherein the second reactor tank is configured to facilitate methanogenesis;
• a membrane module having a membrane configured to filter waste from the digested waste from the second reactor tank to produce a permeate;
• a permeate collection tank is configured to collect and store the permeate generated by the membrane module;
• a pump system having a plurality of pumps to pump waste between the buffer tank, at least one of the first and second reactor tanks, the membrane module, and the permeate collection tank;
• and
• a control system configured to monitor a flow of waste and to control the pump system to control the flow of waste between the buffer tank, at least one of the first and second reactor tanks, the membrane module, and the permeate collection tank.
