What is ORP in the wastewater treatment process? Please, 3Q

ORP** monitoring can reflect the relative amount of oxidizing substances or reducing substances in the pool, ORP** monitoring can also reflect the quality of redox progress, and the use of ORP indicators to adjust the process flow can play a role in half the effort.

Summary. For a water body, there are often multiple redox potentials, constituting a complex redox system. The redox potential is the comprehensive result of the redox reaction between a variety of oxidizing substances and reducing substances.

Although this index cannot be used as an index of the concentration of certain oxidizing substances and reducing substances, it is helpful to understand the electrochemical characteristics of water bodies and analyze the properties of water bodies, and is a comprehensive index.

What is Water Treatment ORP?

Water treatment ORP refers to redox potential, which is used to reflect the macroscopic redox properties of all substances in aqueous solution. The higher the redox potential, the stronger the oxidation, and the lower the redox potential, the stronger the reduction. A positive potential indicates that the solution shows some oxidation, and a negative potential indicates that the solution shows some reduction.

The daily processing capacity is 25000m3 d, using the A2O process, the ORP value of the anaerobic section is about -350mV, and the ORP value of the anoxic section is about -150mV. Is the ORP curve an indication of possible potential problems?

ORP refers to redox potential, oxidation-reduction potential, redox potential Regardless of the form of reaction, the so-called oxidation is the loss of electrons, and the so-called reduction is the acquisition of electrons, which must be accompanied by the electron acceptance process. When a platinum electrode is inserted into a reversible redox system AH2A2E 2H, electrons are donated to the electrode and become a half-cell with a potential corresponding to the reduction power of the system. The potential measured by combining it with a standard hydrogen electrode is the redox potential of the system.

The redox potential value EH is determined by the free energy (or equilibrium constant) of the reduced oxidized H2, pH, and the ratio of oxidized to reduced amounts [OX] [RED].

To put it bluntly, it is the degree of oxygen isolation, which can be measured by potentiometer.

In swim water treatment, ORP refers to the redox potential, mainly: reflecting the strength of the redox potential of chemicals in the water, the level of the redox potential depends on the type and concentration of oxidized substances and reduced substances in the water, and its unit is: MV

What is Wastewater Treatment Process ORP?

ORP is the abbreviation of dissolved oxygen reduction site pH, which can provide information about redox reactions, which is of great significance for wastewater treatment. Generally speaking, the higher the pH value and the higher the ORP value for better dissolved oxygen quality, which represents the water with stronger antibacterial and purification capabilities, contributing to more stable water production and lower pollution.

ORP (redox potential) is an important indicator of water quality, although it cannot independently reflect the quality of water quality, but it can reflect the ecological environment in the aquarium system in combination with other water quality indicators.

ORP in Industrial Wastewater Treatment:

The redox system used in water treatment is mainly the reduction of chromic acid and the oxidation of cyanide. If sodium disulfide or sulfur dioxide is added to the wastewater, hexavalent chromium ions can be turned into trivalent chromium ions. If chlorine or sodium hypochlorite is added, cyanide can be oxidized, followed by the hydrolysis of cyanide to form cyanate.

This chemical reaction process is called a redox reaction system. Redox potential is the measurement of electron activity, which is very similar to the measurement of hydrogen ion activity.

In water, each substance has its own redox properties. Simplely, we can understand that at the micro level, each different substance has a certain redox-reduction ability, and these redox substances can affect each other, and finally constitute a certain macroscopic redox property.

The so-called redox potential is used to reflect the macroscopic redox-reduction of all substances in an aqueous solution. The higher the redox potential, the stronger the oxidation, and the lower the potential, the weaker the oxidation. A positive potential indicates that the solution shows some oxidation, while a negative potential indicates that the solution shows reductivity.
