1. A method for achieving advanced treatment of wastewater comprising:
removing from water to be treated at least some organic compounds and solids in a first module;
at least intermittently exposing the water to be treated to oxygen in the first module;
achieving at least partial denitrification of the water to be treated in the first module;
channeling the water from the first module to a second module comprising an aerated hydroponic reactor; and
channeling water exiting the hydroponic reactor to a top of a third module comprising a vertical-flow wetland adapted to maintain
a population of aquatic invertebrates therein, for achieving BOD removal, nitrification, denitrification, and removal of TSS.
