biostream® ZERO in the food industry

Reliably fighting biofilms and drinking water bacteria such as E. coli, Legionella and Pseudomonas: with the active substance chlorine dioxide, listed under Section 20 of the German Drinking Water Ordinance.

In food processing, water is both an ingredient and a cleaning agent. biostream® ZERO supports consistently high hygiene, from the wash bath to process water.

Food production is an application of biostream® ZERO, in which process and washing water in the food industry is disinfected with chlorine dioxide.

Disinfection of process water in the food industry with biostream® ZERO

Disinfection in processing with biostream® ZERO

Pathogenic germs are fought by the active substance chlorine dioxide, which is listed under Section 20 of the German Drinking Water Ordinance, including pseudomonads (Pseudomonas), E. coli and Legionella.

Our products are used in many areas of the food processing industry:

  • Fresh food is washed in baths dosed with biostream® ZERO
  • In industrial sausage and dough production, "stream ice" is used, to which biostream® ZERO is added to reduce microbial contamination that has already occurred
  • Disinfection of process and utility water in production

From fresh food to production

Killing naturally occurring germs effectively.

Disinfecting fresh fruit and vegetables in a wash bath with biostream® ZERO

Washing fresh food

Fruit, vegetables and herbs straight from nature are washed in baths dosed with biostream® ZERO. This effectively kills naturally occurring germs, for longer freshness and greater safety.

Hand holding crushed ice: "stream ice" with biostream® ZERO for sausage and dough production

Industrial production & "stream ice"

"Stream ice" is used in sausage and dough production: biostream® ZERO is added to the ice to reduce microbial contamination that has already occurred and to support process hygiene.

Your advantages

  • Ready to use within just 3 hours
  • Effective across the entire drinking water pH range
  • Suitable for aluminium tanks
  • 25 times lower dosage requirement than hydrogen peroxide (6 instead of 150 mg/l for disinfecting installations, DVGW code of practice W 291)
  • Highly effective against Pseudomonas aeruginosa, E. coli & coliform bacteria as well as Legionella (Legionella pneumophila)
  • No silver or copper as active substance
  • Oxidative action on cell membrane, proteins and genetic material at the same time, not at a single point of attack

Rules and standards for chlorine dioxide

  • Drinking Water Ordinance (TrinkwV), Section 20: chlorine dioxide is included in the list of permitted treatment substances for disinfection
  • DIN EN 12671: chlorine dioxide generated on site for the treatment of drinking water
  • DVGW W 224: methods for the disinfection of drinking water with chlorine dioxide
  • DVGW W 291 and W 551-3: chlorine dioxide as a proven chemical for cleaning and disinfecting installations
  • Guideline No. 5 of the working group of the German coastal states on ship hygiene: chlorine dioxide for drinking water on board
  • DIN 2001-2: drinking water supply from non-stationary installations such as motorhomes and boats

What each rule means ›

Use & dosage

biostream® ZERO is a two-component concentrate. Once combined, the highly effective chlorine dioxide solution is ready within around 3 hours and is then added to the water being treated, either manually or with a dosing pump. The water's pH value should be between 4 and 10. The concentration required depends on the application and the quality of the source water.

Basic dosage: 10 ml biostream® ZERO per 1 litre of water (equivalent to 10 ml/l)

Non-binding guidance. The product label, operating instructions and the applicable codes of practice are authoritative. Use biocides safely. Material compatibility applies when the recommended dosage and contact time are observed.

Efficacy: study and practice

A study commissioned by biostream® GmbH and decades of practical use demonstrate the performance of the active substance.

Study at Leibniz University Hannover

A study commissioned by biostream® GmbH at the Institute of Food Science and Human Nutrition of Leibniz University Hannover (led by Dr. rer. nat. H.-D. Werlein) confirms in 1,620 individual tests an efficacy of 99.9 % of biostream® ZERO against germs occurring in drinking water, at contact times of only 5 minutes.

biostream® products have been used successfully since 2001 in rail vehicles, on ships, in hospitals and clinics and by well-known beverage manufacturers.

Biofilm study at the University of Hannover

Fighting Legionella and biofilms for good

Legionella (e.g. Legionella pneumophila) are an often underestimated water hygiene problem and the cause of Legionnaires' disease.

They settle in biofilms. The active substance of biostream® ZERO, chlorine dioxide, is included in the list of permitted treatment substances under Section 20 of the Drinking Water Ordinance.

Use biocides safely. Always read the label and product information before use. All statements on efficacy are based on biostream® GmbH's many years of experience as well as information from specialist literature, legislation, codes of practice and positive customer references. Material compatibility applies when the recommended dosage and contact time are observed.

What it is not

Food production is an application, not a separate product: biostream® ZERO is used; quantities and contact times are given in the dosing instructions, not on this page.
