Claim 18:
19. A method for processing wastewater comprising:
directing a wastewater stream to a processing unit;
using said processing unit to perform on said wastewater stream a separation process to separate a solid phase from a liquid phase of said wastewater stream, wherein said processing unit comprises a mesh bag comprising a non-porous plastic material;
using one or more processing units to perform (i) one or more anaerobic digestion processes to reduce a concentration of anaerobic species from said wastewater stream, and/or (ii) one or more aerobic digestion processes to reduce a concentration of aerobic species from said wastewater stream; and
using one or more disinfection units to perform one or more disinfection processes to reduce a concentration of bacteria and/or viruses from said wastewater stream, thereby producing a product stream having drinking-water quality,
wherein said separation process is upstream of any one of said one or more anaerobic digestion processes and said one or more aerobic digestion processes; wherein said separation process comprises sedimentation, flotation, and/or precipitation; wherein said one or more anaerobic digestion processes and said one or more aerobic digestion processes are upstream of any one of said one or more disinfection processes.
