Abstract: Described are wastewater treatment systems comprising a biologically active conduit defining a single, confined serpentine flow path twisting from top to bottom portions. The system establishes sequential aerobic, anoxic, and anaerobic treatment zones populated with zone-specific biological chips containing dominant biologically active media. Mesh separators prevent biological chip displacement between zones while allowing wastewater flow. The system receives influent wastewater through a bottom opening and dispenses treated effluent from the same opening following simultaneous batch treatment across all zones. Methods include wastewater treatment processes, modular assembly techniques, and attribute management systems using adjustable bypass valves and venturi-based air introduction for precise dissolved oxygen control. The systems achieve enhanced PFAS removal by reducing organic matter competition for granular activated carbon (GAC) adsorption sites, extending GAC operational life by at least 25%.

Abstract: A method for producing a plant life enhancing product is described. The method includes: (i) anaerobically digesting agricultural residue to produce an anaerobically activated organic residue and an ammonia-enriched water; (ii) aerobically digesting the ammonia-enriched water to produce an aerobically activated organic residue; and (iii) blending the anaerobically activated organic residue with the aerobically activated organic residue to produce the plant life enhancing product.
