Neutral and acidic anolyte | The disinfectant

The production of acidic anolyte water with a pH value of pH2 to pH3,5 (redox: -+1000mV to +1200mV) and also the production of basic catolyte water with a pH value of pH10 to pH13 (redox: -900mV up to -950mV) is also possible reliably and highly efficiently with our systems.

The special feature of the ECO systems is that all the water first passes through the anode and then through the cathode and can therefore produce a unique alkaline water in the flow, which certainly cannot contain pathogenic germs and chemicals, as these are caused by reduction reactions first and then eliminated or converted into a harmless form through oxidation reactions.

The ECO ionizers are therefore not only a flow-through electrolysis device but also the most effective and safest filter that has yet to find its equal.

DESCRIPTION:

Our Envirolyte systems (except ECO series) and the ECA Plus water tractor produce two different activated solutions through electrolysis from salt (brine) and water with polymer or ceramic membranes through a chemical reaction. Depending on the device, between 5 – 7 g salt / liter dosed into the fed water. That's not a little, it's a 5%-7% salt brine! An alternative semi-professional system ECA Plus water tractor However, it requires less salt.

ACIDIC ANOLYTE:

The acidic anolyte solution can be used wherever effective disinfection and sterilization are important, the pH value is not that important and where there is no risk of corrosion. Acid anolyte is a very powerful and fast-acting disinfectant against all bacteria, viruses, spores, mold, fungi and algae, even when diluted with water or sprayed into the air as an aerosol.

NEUTRAL ANOLYTE:

ANK-Neutral anolyte solution is used wherever the pH value is important, for example to avoid corrosion and where possible evaporation of active chlorine is undesirable. Neutral anolyte is highly effective against a wide range of pathogens such as bacteria, viruses, spores, mold and fungi.

CATHOLYTE SOLUTION:

The catholyte solution is alkaline and serves as an excellent washing liquid.

It also removes heavy metals from the water.

FUNCTIONALITY:

In a typical way an Envirolyte device works, the anolyte is collected in a container and then dosed into the water flowing through it.

The dosage depends on the setting regarding the amount of water and the quality (properties) of the water and is controlled by a flow meter connected to a dosing pump.

The devices can be stand-alone, e.g. for spraying, cleaning, CIP disinfection, etc. or they can be used as part of a continuous process in more complex systems.

Special customer-specific functions can be integrated.

INFORMATION ABOUT ANOLYTE:

In general, the anolyte refers to that part of the electrolyte that is directly influenced by the anode during electrolysis. The catholyte is defined analogously.
Technically, the term is broader in that the entire electrolyte in the anode space of a flow-through electrolysis reactor separated by a membrane is referred to as anolyte.

For example, in sodium chloride electrolysis, the chloride anions would be oxidized to chlorine at the anode, and water would be reduced to hydrogen and hydroxide ions at the cathode.

Due to the strongly negative deposition potential of sodium, no deposition of the metal occurs. The chlorine partially reacts with water to form hypochlorous acid.

Such an electrolytically created solution of chlorine and hypochlorous acid can be used in other processes under the name anolyte, e.g. B. can be used as an oxidizing agent or disinfectant.

The caustic soda created at the cathode in this example process represents the catholyte and can also be reused.

Overview of the cathode reactions, the solution that is created at the cathode is called a catholyte:

The solution formed at the cathode is an effective cleaning and degreasing agent.

Development of hydrogen:

2H2O + 2e- = H2 + 2OH- (E0 = -0.828 V)
2H2O = H2 + 2•OH

Formation of hydrogen and caustic soda:

2Na+ + 2H2O + 2e- = H2 + 2NaOH
2Na + 2H2O = H2 + 2NaOH Na+ + OH- = NaOH

Sodium dissociation and formation of hydroxyl ions:

Na+ + e- = Na
2•OH + 2e- = 2OH-
O2 + 2H2O + 4e- = 4OH-

Anolyt N, a mixture of these two solutions, is an extremely effective cleaning and disinfectant.

Overview of the anode reactions, the solution that is created at the anode is called anolyte:

Development of hypochlorous acid (one of the best disinfectants):

Cl2(aq) + H2O = HCl (=H+ + Cl-) + HOCl
Cl- + H2O = HOCl + H+ + 2e-
2Cl- + H2O = HOCl + HCl + 2e-
2Cl- + H2O2 = 2HOCl + 2e-
ClO- + H2O = HOCl + OH

Formation of hypochlorite ions:

Cl2(aq) + 2OH- = ClO- + Cl- + H2O
Cl2(aq) + H2O = ClO- + Cl- + 2H+
HOCl = ClO- + H+
2HOCl ClO- = ClO3- + 2Cl- + 2H+

Formation of free radicals, oxygen and hydrogen peroxide

H2O = H+ + •OH + e-
•OH + •OH = H2O2
H2O = •O + 2H+ + 2e
O2- = 2O + e-

Creation of ozone:

3H2O = O3 + 6H+ + 6e-
•O + O2 = O3
O2 + H2O = O3 + 2H+ +2e- (E0 = 2.07 V)

Formation of oxygen:

2H2O = O2 + 4H+ + 4e-
4OH- = O2 + 2H2O + 4e-
H2O2 = O2 + 2H+ + 2e-
2Cl2 + 2H2O = 4H+ + 4Cl- + O2

Oxygen and chlorine gas evolution:

4Cl- + 2O3 + 4H+ = 3O2 + 2Cl2 + 2H2
2Cl- + 2O3 = 3O2 + Cl2 + 2e-

Evolution of chlorine gas and dissolved chlorine

2Cl- = Cl2(g) + 2e- (E0 = 1.359V)
2HOCl + 2H+ + 2e- = Cl2 + 2H2O (E0 = 1.63V)
Cl2(g) = Cl2(aq)
