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.")

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)

Bulk Water-Hauling System

A public water system that provides water piped into a carrier vehicle and withdrawn by a similar means into the user's storage facility or vessel. The term includes, but is not limited to, the source of water, treatment, storage or distribution facilities. The term does not include a public water system that provides only a source of water supply for a bulk water hauling system.

Buffering Capacity

The ability of a solution to neutralize acids without a significant change in pH. Buffering capacity is also known as alkalinity and is measured in mg/L of equivalent CaCO3, a common buffer.
