Urine and wastewater treatment system

A liquid waste treatment system, the system comprising:

• an ultra-filtration stage comprising:
• an ultra-filtration filter configured to separate the liquid waste into a first permeate and a first concentrate, and
• a diffuser positioned at an inlet to the ultra-filtration filter, the diffuser connected to an air blower and configured to introduce air into the liquid waste to reduce the density of the liquid waste and to generate a crossflow within the ultra-filtration filter;
• and
• a reverse osmosis stage configured to receive the first permeate from the ultra-filtration stage and separate the first permeate into a second permeate and a second concentrate, the second permeate being a non-potable water for use or re-use.
