Germ-free drinking water – safe with certified UV-C technology

oxytec systems for effective disinfection of drinking water – without chemicals, without residues

Drinking water is a hygiene-critical resource in both production and buildings. Even with regularly tested supplies, germs, bacteria, and viruses can multiply in pipes, tanks, or taps – especially in stagnant water, warm temperatures, or backflows. This can lead to hygiene problems, system contamination, or health hazards.

With oxytec’s certified UV-C systems, drinking water becomes 99.999% germ-free – without chemicals, taste changes, or environmental impact. The technology is durable, low-maintenance, and safe for use in flow-through operation.

Common sources of contamination in drinking water systems

Source Potential for pollution Special features
Piping systems Biofilm, Legionella, Pseudomonas Stagnation, dead ends, irregular use
Storage tanks & containers Germ proliferation in heat, sediments, algae Especially in stainless steel or plastic tanks
Backflows / foreign matter Germs from systems, fittings, or tank trucks Hazard due to inadequate backflow or filter protection
Final delivery points Hygiene problems at taps, vending machines, devices Contaminated outlets, invisible sources of germs

Why disinfecting drinking water with UV-C makes sense

Bacteria and viruses can multiply uncontrollably despite standard values in the system.

Chlorination or ozonation leave residues, alter taste, and are not always permitted.

UV-C acts directly and physically—without additives or reaction byproducts.

The effect is sustainable, certifiable, and reliably documentable.

The systems are also suitable for drinking water used in operations and sensitive applications.

Legal requirements & hygiene standards

  • Drinking Water Ordinance (TrinkwV): mandatory microbiological requirements
  • DVGW W 294-1: Guideline for UV systems in drinking water technology
  • HACCP integration: safe water quality as CCP or oPRP
  • Verification for health and food authorities

oxytec supplies certified systems with test reports, calibration, and documentation.

FAQ – Frequently Asked Questions

Which germs are safely inactivated by UV-C?

oxytec UV-C systems reliably eliminate:

  • Bacteria (e.g., Escherichia coli, Pseudomonas, Legionella)
  • Viruses (e.g., norovirus, adenovirus, rotavirus)
  • Parasitic pathogens (e.g., Cryptosporidium, Giardia)
  • Spore-forming bacteria (e.g., Clostridium)

Germ reduction is up to 99.999% (5 log levels) – scientifically proven and certified.

How does disinfection without chemicals work?

The water is passed through a UV-C chamber in a flow-through process.

The radiation at 254 nm destroys the genetic material of germs.

The process is physical, immediately effective, and leaves no residue.

No aftertaste, no dosing agents, no reaction products.

How much maintenance do UV systems require?

The systems are very low-maintenance:

  • UV-C lamps have a service life of 8,000–10,000 operating hours
  • Regular lamp replacement once a year, depending on operation
  • The quartz protective cover should be inspected regularly and cleaned if necessary
  • Optional automatic runtime monitoring and replacement indicator

Are the systems certified for use in drinking water pipes?

Yes – Oxytec offers:

  • DVGW-approved models in accordance with W 294-1

  • Devices tested in accordance with DIN EN 14897 / EN ISO 9001

  • Systems with validated germ reduction and calibration protocol

  • Approval documents for drinking water authorities or health departments

Can UV-C disinfection be integrated into existing drinking water pipes?

Yes – the systems are:

  • compact and modular, for pipes from DN 20 to DN 100+,
  • can be installed horizontally or vertically, even in confined spaces
  • retrofittable to central feed or in partial circuits
  • can be integrated into existing water filters, softeners, tank systems, or extraction points

How much energy does a UV-C drinking water system consume?

Very low:

  • Typical power consumption: 20–80 watts, depending on flow rate
  • Electricity costs usually < 1 €/month in continuous operation
  • No additional costs for chemicals, storage, or dosing pumps

How is effectiveness proven and documented?

Oxytec provides the following upon request:

  • Proof of germ reduction (log levels) for specific pathogens
  • Certificates, calibration protocols, and maintenance records
  • Support with registration as oPRP or CCP in the HACCP system
  • Audit-ready documentation for authorities, certifiers, and food inspectors

Can it also be used in sensitive areas such as food production or hospitals?

Yes – UV-C disinfection is ideal for:

  • Food processing (washing water, ice machines, process water)
  • Beverage production (brewing water, mixing circuits, tank rinsing)
  • Hospitals, care facilities, commercial kitchens, schools
  • All facilities with increased hygiene requirements or mandatory testing

Is UV-C safe for the piping system?

Yes – UV-C only affects the water load inside the reactor:

  • No corrosion, no material degradation, as no oxidizing agents are used
  • Suitable for stainless steel, plastic, and composite systems
  • No pressure loss if correctly dimensioned
