Resumen

MENENDEZ GUTIERREZ, Carlos  y  DUENAS MORENO, Jaime. The Biological processes of wastewater treatment from a non-conventional vision. riha [online]. 2018, vol.39, n.3, pp.97-107. ISSN 1680-0338.

The biochemical oxygen demand (BOD) is very frequently used in wastewaters characterization. It allows to know the amount of organic matter that can be degraded by microorganisms in a biological wastewater treatment. However with the chemical oxygen demand (COD) it is possible to know the biodegradable and non-biodegradable fractions including those inorganic compounds that can be chemically oxidized. The COD is commonly used as a variable to define the carbonic material (biodegradable or non-biodegradable), present in wastewaters. The objective of this paper is to show a non-conventional vision from an actual perspective in the wastewater treatment by biological processes.

Palabras clave : biodegradable; biochemical oxygen demand; chemical oxygen demand; non-biodegradable; biological processes.
