Abstract: System and method for a urine and wastewater treatment are described. The urine and wastewater treatment system can include a tank configured to receive liquid waste (102), an air blower (114) configured to blow air into the liquid waste to reduce the density of the liquid waste and to generate crossflow, and a filtration unit comprising an ultra-filtration stage (104) comprising a first permeate outlet and a first concentrate outlet and a reverse osmosis stage (112) comprising a second permeate outlet and a second concentrate outlet. The reverse osmosis stage is configured to receive a first permeate from the ultra-filtration stage.

Abstract: System and method for volume reduction solids treatment for fecal waste are described. The system can include a pasteurizer (102) configured to receive a slurry batch and heat the slurry batch at an elevated temperature for a time period to produce a pathogen free slurry. The system can also include a mechanical dewatering press (104) configured to compress the pathogen free slurry to separate a liquid phase from a volume reduced solid waste. The volume reduced solid waste being formed into a feces cake. The system can also include a means to remove the liquid phase and a drying tunnel (106) comprising a conveyor housed and an air duct system. The air duct system configured to propel forced air over the feces cake.
