Unlike dangerous chlorine, the GREENOX biocide does not form toxic carcinogens, trihalomethanes, ketones, or chloramines, and is a harmless eco-friendly agent for humans, animals, and the environment.
How the GREENOX disinfectant works

Versatility
GREENOX chlorine dioxide (ClO₂) is a broad-spectrum disinfectant:
- Disinfection of air and water (drinking water, pool purification, wastewater)
- Sterilization of instruments, premises, and equipment in medicine
- Disinfection of surfaces, technological equipment, food products, and containers
- Elimination of odors and removal of biofilms where chlorine and sodium hypochlorite fail

Bacteria
GREENOX destroys the cell envelope and nucleus of bacteria through chemical oxidation rather than chlorination[cite: 6]. The bactericidal mechanism of action precludes the development of resistance: microorganisms are completely destroyed and cannot develop immunity, which allows the use of chlorine dioxide on a continuous basis without the need for alternative biocides[cite: 6].

Viruses
Due to its high oxidative capacity, GREENOX destroys the protein envelope of viruses and their genetic material (RNA/DNA), rendering them non-viable[cite: 6]. The virucidal effect is achieved through oxidation, not chlorination[cite: 6]. It is effective even at low concentrations that are absolutely safe for humans[cite: 6].

Biofilms
Chlorine dioxide remains a gas in solution; its molecules penetrate deep into layers of mucus and destroy the polysaccharide matrix that holds the biofilm together, whereas traditional disinfectants only affect the surface of the deposits[cite: 6]. This makes GREENOX the No. 1 agent for combating slime, biofouling, and Legionella in water circulation systems[cite: 6].

GREENOX chlorine dioxide — a modern replacement for chlorine and hypochlorite
GREENOX, based on chlorine dioxide, is used for water disinfection, biofilm removal, and the decontamination of premises, equipment, and water supply systems. It provides safer, more effective, and environmentally friendly disinfection compared to traditional chlorination.
GREENOX is more effective than chlorine and traditional disinfectants
GREENOX is particularly valued for its ability to destroy resistant pathogens (anthrax, botulism spores) and highly lethal viruses (COVID-19, rabies, ASF/ASFV, Ebola), as well as parasites resistant to chlorination.
Chlorine

GREENOX

Pungent chlorine odor
No color or pungent odor
Reacts with amines and nitrogen-containing organic matter to form chloramines, which produce a characteristic smell and taste. The smell of chlorine is not 'cleanliness,' but a by-product of chlorination.
GREENOX does not form significant amounts of chloramines, ensuring clean water without eye irritation, smell, or taste.
Does not remove biofilms
Completely removes biofilms
The chlorine molecule does not penetrate the polysaccharide matrix of a biofilm. Even at high doses, it only suppresses surface bacteria without eliminating the colony from within.
The chlorine dioxide molecule remains a gas in solution and penetrates the polysaccharide matrix of the biofilm, destroying it from within. GREENOX is an effective biofilm remover.
pH dependent
Not pH dependent
Chlorination efficiency drops sharply at pH > 7.5. In concrete pipes and DHW systems, where pH is usually alkaline, sodium hypochlorite performs poorly.
GREENOX biocidal activity is stable in the pH range of 4–10. Effective water disinfection in concrete pipes, pools, and wells without pH adjustment before treatment.
Not applicable for air disinfection
Effective for air disinfection
Air disinfection with chlorine is impossible due to rapid evaporation and high risk to the respiratory tract even at low concentrations.
Air disinfection in rooms, air ducts, and ventilation systems is one of the key advantages of GREENOX.
Forms trihalomethanes and carcinogens
Does not form trihalomethanes — eco-friendly
Leads to the formation of toxic by-products (chlorophenols, trihalomethanes, haloacetic acids, etc.) when reacting with organic matter present in water.
GREENOX produces almost no organochlorine by-products, including trihalomethanes. Chlorine dioxide's environmental safety is confirmed by the EPA (USA) and the WHO: it is approved for drinking water disinfection instead of chlorine.
Weak algaecide
Strong algaecide
Chlorine kills algae in pools and open reservoirs only at very high doses, which create unpleasant odors and are harmful to eyes and skin.
A strong algaecide at the ultra-low doses used for water disinfection, 0.1 – 0.5 mg/l.
High corrosivity
Low corrosivity
Actively reacts with metals and degrades organic materials, plastics, and rubber seals, significantly reducing equipment service life.
GREENOX (ClO₂), at working concentrations, does not damage metals, plastic components, or most materials, unlike chlorine-based disinfectants.

Pathogens destroyed by GREENOX
GREENOX has the broadest biocidal spectrum among disinfectants. It is especially valued for its ability to destroy resistant pathogens (anthrax), highly lethal viruses (COVID-19, rabies, ASF/ASFV, Ebola), helminth eggs and larvae, as well as protozoan parasites resistant to water chlorination. Here are just a few examples:
Viruses
Coronaviruses (COVID-19, SARS, MERS)
Destroys the lipid envelope and viral RNA through direct oxidation—without chlorination. Effective at concentrations safe for humans.
African Swine Fever (ASF/ASFV)
A highly contagious, fatal infection affecting pigs of all breeds and ages. GREENOX is a reliable bactericidal and virucidal agent for disinfecting livestock premises and equipment.
Influenza (Influenza A/B, Avian H5N1, Swine H1N1)
Destroys the influenza virus envelope and blocks its reproduction. Effective for sanitary treatment of premises and ventilation systems during epidemics.
Rotavirus and Norovirus
The main causative agents of intestinal infections transmitted via water and food contact. Destroyed at standard water disinfection doses.
Hepatitis A, B, C, E
Destroys the protein envelope and blocks reproduction. Used for disinfecting medical equipment and work surfaces in healthcare facilities.
Poliovirus (Polio)
One of the viruses most resistant to common disinfectants. GREENOX chlorine dioxide destroys it even at low concentrations.
Enteroviruses (ECHO, Coxsackie)
Causative agents of GI and nervous system infections transmitted through water. Effectively neutralized during bactericidal disinfection of tap water and pools.
Adenoviruses
Cause respiratory and eye infections. Especially relevant for pools and water parks—GREENOX eliminates them in water without the smell of chlorine.
Ebola virus
Studies confirm that chlorine dioxide destroys the Ebola virus in water and air during sanitary treatment of premises.
Herpes virus (HSV-1, HSV-2)
GREENOX reduces viral infectivity by destroying its envelope, rendering it unable to infect cells. Used for disinfecting surfaces and instruments in medical facilities.
Rabies virus
Deactivated during sanitary treatment of surfaces and equipment with GREENOX solution. Relevant for veterinary clinics and livestock farms.
HIV (Human Immunodeficiency Virus)
Not used for treatment, but is deactivated in laboratory conditions. Used as a virucidal agent for disinfecting medical equipment.
Bacteria and Spores
Salmonella (Salmonella spp.)
The main cause of food poisoning and typhoid fever. Destroyed by GREENOX during disinfection of food equipment, containers, and production surfaces.
Legionella (Legionella pneumophila)
The main problem in water supply systems, cooling towers, and air conditioners. GREENOX is the only bactericide that kills Legionella inside biofilms, where chlorine and sodium hypochlorite fail.
Anthrax (Bacillus anthracis)
Effective against the causative agent of anthrax and its spores—one of the most resistant biological agents. The sporicidal effect of GREENOX is confirmed by independent studies.
Tuberculosis (Mycobacterium tuberculosis)
Resistant to common bactericides and chlorination. GREENOX is effective even against resistant dormant forms of Mycobacterium tuberculosis during medical facility disinfection.
Cholera (Vibrio cholerae)
GREENOX kills the cholera vibrio and its biofilms even in murky, warm water—where disinfection with chlorine and bleach loses effectiveness.
Staphylococci (Staphylococcus aureus)
Including MRSA (methicillin-resistant S. aureus). Destroyed by GREENOX during bactericidal treatment of medical facilities and surfaces.
Listeria (Listeria monocytogenes)
Dangerous for pregnant women, can cause meningitis. Critically important to destroy in food production; GREENOX provides reliable disinfection of equipment and work surfaces without toxic residues.
Leptospirosis (Leptospira spp.)
Affects the liver, kidneys, and central nervous system. Bactericidal water disinfection in wells and supply systems with GREENOX prevents waterborne infection.
Bacillus spores (Bacillus subtilis, Bacillus cereus)
Spores are resistant to common water chlorination and sodium hypochlorite. GREENOX chlorine dioxide has a pronounced sporicidal effect and destroys them.
Clostridium botulinum spores
The causative agent of botulism. Spores are extremely resistant—not susceptible to standard doses of bleach or sodium hypochlorite. GREENOX destroys them due to its high oxidative capacity.
