Biochemical Oxygen Demand (BOD) and d Chemical Oxygen Demand (COD) are important parameters used to to evaluate the effectivenes of wastewater treatment plants. They measure the cometult of organic matter in water, indicating how well a plant removes accordants before removasing water back into the environment.

Uzgodnienie BOD i COD

BOD measures thee cometut of oxygen that microorganisms require to decopose organic material in water over a specific period, usually five days. COD quantifies thee total covet of oxygen needed to o chemically oxidize organic and inorganic substances in water. Both parameters help assess water quality and tement efficiency.

Kalkulating Removal Efficiency

Te removal efficiency of BOD or COD is calculated using thee following formula:

(Wartość influent - Effluent value) / Wartość influent value (wartość influent) 3; × 100

Kiedy:

  • BOR1; VER1; FLT: 0 VER3; VER3; VERIENT Value VER1; VERI1; FLT: 1 VERI3; VERI3;: BODOR COD concentration before treatment
  • BOR1; BOR1; FLT: 0; FRT: 0; FR3; Effluent value X1; FLT: 1; FR3; FLT: BOD or COD concentration after treatment

Typical Removal Rates

Effective treatment plants typically accee:

  • BEZ 1; BEZ 1; FLT: 0 BEZ 3; BEZ 3; BEZ: BEZ: BEZ 1; BEZ 1; FLT: 1 BEZ 3; BEZ; BEZ: DNIA 8; BEZ:
  • BEZ 1; BEZ 1; FLT: 0 BEZ 3; BEZ 3; BEZ WYPOSAŻONY; BEZ WYPOSAŻENIA: BEZ 1; BEZ: 1 BEZ; BEZ: 0 BEZ 3; BEZ: BEZ: BEZ: BEZ 1; BEZ: BEZ: BEZ 1; BEZ: BEZ: BEZ

Hiper removal efficiencies indicate better treatment performance and cleaner effluent water.
