Wastewater Treatment Process Flow Diagram - Biological & Chemical Stages #308882 (License: Personal Use)

The diagram depicts a multi-stage wastewater treatment system combining chemical pretreatment (Chemieabwasser), carbon-based biological treatment (C-Biologie), nitrification (Nitrifikation), and denitrification (Ablauf zur Denitrifikation). Key control elements include two PLC units (PLC 1 and PLC 2), overflow management, and sludge handling via ÜSS ZKB and ÜSS NKB units, all feeding into a final effluent (EFFL) discharge point. The system integrates process tanks, splitters, and sensor-driven automation for optimized performance.

Used in technical documentation, engineering presentations, or municipal utility websites to explain treatment workflows; targets environmental engineers, plant operators, and regulatory compliance teams seeking process transparency.
