The transformation of solutions with a low content of mineral salts into an activated metastable state, by unipolar electrochemical action, generates two separate and distinct compounds, generically called anolyte and catholyte that correspond to their derived electrode chambers:
- The anodic (positively charged) solution contains a variety of oxidants, including hypochlorous acid, singlet oxygen, peroxide anion, superoxide, ozone, monoatomic oxygen and free radicals, which are known to possess antimicrobial properties. Analytes have strong oxidizing properties with a pH between 2.5 and 8.5 and a redox potential (ORP) of +600 to +1200 mV.
- The cathodic (negatively charged) solution develops detergent properties, contains sodium hydroxide in a highly excited state. The catholyte solutions are antioxidants with a pH between 10.5 and 12.0 and an ORP between -600 and -900 mV.ù
The application of this innovative system also in agriculture is interesting, in particular in hydroponics systems.
In both agriculture and horticulture, yield is related to the quality of pest control or the prevention and effectiveness of treatments.
Anolyte is a natural disinfectant and sterilizing product, very powerful against all types of bacteria and also algae and fungi. It can be used pure, diluted with water or sprayed in the air. It is generally used in agriculture for maintaining sanitary cleanliness and fighting fungi and other germs that decimate crops.
The special technology allows the production of a risk-free biocide product (fungicide, germicide, bactericide).
Anolyte is an excellent natural biocide product to reduce the number of germs and good disinfection greatly increases the yield. The use of electrolysis for the production of reducing-oxidizing solutions is used in water purification and decontamination processes, as well as to transform water or diluted electrolyte solutions into antimicrobial, washing, extractive and other useful solutions. Maintaining clean water in hydroponics systems is essential to ensure product quality.
This is largely due to the high activity of electrochemical activation, the use of low-cost raw materials and ease of production. The system produces a liquid, degradable and non-toxic disinfectant, capable of destroying bacteria, spores, moulds, viruses, fungi, yeasts, biofilms on pipes and removing odours. Its operation requires only water, sodium or potassium chloride (salt) and electricity. THE SYSTEM IN DETAIL It consists of an electrolysis cell containing two electrodes, a cathode and an anode, separated by a diaphragmatic membrane. An aqueous solution consisting of filtered and softened water and, depending on the application, sodium chloride (NaCl, salt) or potassium chloride (KCl) is inserted into the cell. Using electricity with predefined and controlled amperage and voltage values, the cell produces an electrically activated liquid. This unipolar electrochemical activation created by potential gradients of millions of volts per cm2 between the anode and cathode terminals leads to the creation of solutions whose pH, redox potentials and other physicochemical properties lie outside the range that can be achieved by conventional chemical means.
The neutral anolyte is produced from water and salt thanks to a membrane electrolysis technique. An electric current circulates in the saturated saline solution between two metal elements (anode and cathode). The mixture breaks down into two products, acid anolyte (pH between 2 and 5) and catholyte (pH between 11 and 13). The mixture of both solutions is transformed into a neutral anolyte, i.e. water whose pH is neutral but provides a redox potential greater than 750 mV (that of water with chlorine is 400 mV). The neutral anolyte acts by contact with fungi and bacteria without altering the physiology of the plant material.
