What is the range of orp value in the domestic sewage treatment aerobic tank
By Zhao from Onlyzone,a manufacturer of water treatment bio ceramic ball filter media in China.
The orp value should be above +400mv in the domestic sewage treatment aerobic tank. (The aerobic unit generally uses a dissolved oxygen meter with a value of 2~3mg/L)
ORP:
Oxidation-reduction potential, referred to as ORP (abbreviation of Oxidation-Reduction Potential in English) or Eh. ORP has been used for a long time as a comprehensive indicator of the environmental conditions of the medium (including soil, natural water, medium, etc.), and it characterizes the relative degree of oxidation or reduction of the medium.
definition:
ORP value (Oxidation-Reduction Potential) is an important indicator of water quality. Although it cannot independently reflect the quality of water quality, it can reflect the ecological environment of the aquarium system in combination with other water quality indicators.
In water, each substance has its own redox properties. Simply, we can understand that: on the microscopic level, each different substance has a certain oxidation-reduction ability, and these substances with different oxidation-reduction properties can interact with each other, and finally constitute a certain macro-oxidation-reduction ability. The so-called oxidation-reduction potential is used to reflect the macroscopic oxidation-reduction properties of all substances in the aqueous solution. The higher the redox potential, the stronger the oxidation, and the lower the potential, the weaker the oxidation. A positive potential means that the solution shows a certain oxidation, and a negative potential means that the solution shows a reduction.
