Transportable wastewater treatment systems and methods

Abstract

Transportable wastewater treatment systems and wastewater treatment methods are provided, which employ a clarification unit to treat highly polluted wastewater (e.g., with BODs over 400 mg/l and up to 1500 mg/l) with a small footprint and without elaborate infrastructure or even without grid-based energy sources. The clarification unit comprises an anaerobic digestion unit configured to receive influent and reduce an organic load thereof to yield a first stream, an aerobic anoxic air lift reactor configured to treat the first stream and further reduce the organic load thereof to yield a second stream, and an aerobic unit configured to clarify the second stream and deliver effluent, the aerobic unit comprising a plurality of vertical sheets configured to support growth of algae on biofilm, a sprinkling system configured to sprinkle the second stream onto the vertical sheets, and an organic matter removal unit configured to collect organic mass falling off the vertical sheets.
