<p>A treatment system for wastewater having a tank with a vertically disposed lower anaerobic treatment zone (21), a middle microaerophilic treatment zone (22) and an upper aerobic treatment zone (23). A baffle (101) extends vertically in the tank to define an influent section (I) and an effluent section (E). The heavier biosolids drop to the lower anaerobic zone and the lighter components rise through the effluent section through the microaerophilic and aerobic sections. A lift tube (91) lifts liquid and lighter solid components back into the influent section.</p> |
