What exactly is the ORP of water treatment?

ORP is the redox potential, and the redox potential often has a variety of redox pairs for a water body, constituting a complex redox system, and its redox potential is the comprehensive result of the redox reaction between a variety of oxidizing substances and reducing substances.

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 process of electron acceptance. When a platinum electrode is inserted into a reversible redox system, electrons are donned 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.

For a water body, there are often multiple redox potentials, constituting a complex redox system. Its 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.

METTLER TOLEDO has refillable pH and redox electrodes, hygienic pH probes for sterile applications, rugged pH probes for harsh applications, pH probes for pure and ultrapure water, and refillable pH probes that give you the ability to select a specific reference electrolyte that fits your application needs. KCl electrolyte provides high exudation for improved diaphragm cleaning. Viscolyt has a lower exudation and therefore prolongs the refill interval.

Calcolyt can be used in applications where there is a risk of calcium carbonate precipitation. The right electrolyte means better accuracy and reliability in pH measurements.

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.
