C

Carbonaceous BOD (cBOD)

The stage of decomposition that occurs in biological treatment processes when aerobic bacteria, using DO, change carbon compounds to carbon dioxide; cBOD is sometimes referred to as "first-stage BOD" because the microorganisms attack organic or carbon compounds first. (Nitrogen compounds are targeted second, sometimes referred to as nBOD or "second stage BOD.")

Carbonate System

Major acid/base system that produces a chemical reaction in water distribution systems. The carbonate system is comprised of:

  • Carbonic acid (H2CO3),
  • Bicarbonate (HCO3), and
  • Carbonate (CO32)

cBOD

cBOD (Carbonaceous BOD)

The stage of decomposition that occurs in biological treatment processes when aerobic bacteria, using DO, change carbon compounds to carbon dioxide; cBOD is sometimes referred to as "first-stage BOD" because the microorganisms attack organic or carbon compounds first. (Nitrogen compounds are targeted second, sometimes referred to as nBOD or "second stage BOD.")

Critical Asset

Components of a water or waste water treatment system that are necessary to meet mission objectives (providing drinking water that meets or exceeds the National Drinking Water Standards, providing adequate water pressure to meet public safety needs, maintaining water service to critical users, maintaining wastewater collection system to protect public health, and providing wastewater treatment that meets the National Pollution Discharge Elimination System standards.
