LESSTEC SERVICES

Lesstec offers high-quality and complete disinfection of drinking water pipes. The treatment of the pipe with the L.E.S.S. disinfection system aims at the formation of a healthy, natural and unaffected biofilm, which remains stable when the pipe material is later used with clean drinking water and guarantees an inconspicuous microbiological finding.

GOAL AND MODE OF OPERATION PRINCIPLE

Three-stage, fully comprehensive disinfection of drinking water pipes:

  1. UV-C radiation (inactivation process of pathogens and germs by UV-C)
  2. disinfectant spray system (bactericidal effect of disinfectant (e.g. alcohol) in remote areas of the pipeline such as pipe joints)
  3. fumigation system with carbon dioxide or nitrogen (stunning of microorganisms and invertebrates by flushing out).

These three combinable processes sustainably remove germs and invertebrates

AREA OF APPLICATION

Any piping and piping materials, especially:

  • in stagnation areas
  • in pipes affected by microbial contamination
  • in pipes affected by (microbiologically) contaminated water (e.g. after floods)
  • in pipes in which thermal disinfection is not possible as a prophylactic alternative to chlorine disinfection for new installations
  • for domestic installations
  • for temporary installations
  • in hoses (fabric or plastic) used for the emergency supply of drinking water.

Field of application/ Key figures

  • DN 80 to DN 450
  • independent of pipe material
  • Pipe lengths of up to 500 m can be safely disinfected in a single pass
  • Pull-through speed from 1 to 6 m

LOGGING / TRANSPARENCY

The logging of each of the three procedures guarantees a complete record and allows the output of a disinfection protocol.

CONCLUSION

The bactericidal effect of UV-C radiation is based on the fact that it efficiently destroys the DNA of viruses, bacteria and germs. Multiplication of the pathogens is no longer possible, so that comprehensive disinfection is guaranteed and re-germination can be prevented. No chemicals are used and thus the environment is protected. During the disinfection process using UV-C radiation, no harmful by-products are produced and overdosing is ruled out.

The disinfection performance is fast and sustainable. This leads to a time and cost advantage compared to conventional disinfection methods. Sustainable disinfection can be guaranteed in just one pass.

TRIGGER POINTS

Treatment with the L.E.S.S. disinfection system stands for:

  • safe disinfection
  • sustainable removal of pathogens and germs through their inactivation: no post-contamination
  • no environmental pollution due to repeated chlorine disinfections
  • time and cost savings
  • Transparency through careful automatic logging
