An anaerobic process tank (12) receives the concentrated wastewater (CWW) from the solar still (11) and produces digested waste sludge and a process liquid (PL) therefrom through anaerobic digestion. A membrane tank (20) receives the process liquid (PL) from the anaerobic process tank (12), and also receives the condensed water (CW) from the solar still (11). Through membrane filtration, the membrane tank (20) produces purified water (PW) and retained wastewater (RWW). The retained wastewater (RWW) is recirculated back to the anaerobic process tank (12).
