Silver Peroxide Clean & Disinfection

WHAT IS ‘SILVER PEROXIDE’ (MICROCHEM M381)?

Silver peroxide (MICROCHEM M381) is an eco-friendly, multi-component, oxidising biocide.  A highly effective sanitising solution is formed utilising a stable combination of Hydrogen Peroxide and Silver ions.  This combination is so effective that it creates a biocide 20 times more powerful than that of hydrogen peroxide.  Other benefits include:-

  • It is odourless
  • It will not alter the taste, smell or colour of food
  • It is effective in water temperatures ranging from 0 to 95°C
  • No neutralisation is required after disinfection
  • It is biodegradable

WHEN SHOULD IT BE USED?

MICROCHEM M381 can be used routinely for the disinfection of water storage tanks, cooling towers and mains systems.

During clean and disinfection, MICROCHEM M381 is dosed to achieve 100 ppm with a contact time of one hour.  At this concentration, it does not require neutralising and is drinking water safe.  We recommend the disinfectant is pulled through to all working outlets, but any that cannot be accessed during the process will be reached next time they are in use.  This includes showers and taps and can be especially beneficial when time constraints for the tank ‘downtime’ are an issue.  It is also less reactive than other biocides such as Chlorine or Ozone, which stay in the water for a significantly shorter period of time.  By using solutions of MICROCHEM M381, protective levels of biocide can be maintained in water systems for 14 days or more and therefore provide protection during "Shut downs".

It should not be used in Healthcare environments if water is feeding instruments (such as dialysis) or direct patient care.

IS IT SAFE TO DRINK?

MICROCHEM M381 is approved by the Drinking Water Inspectorate for correct dosage to drinking water systems for up to 90 days per year.  It is not therefore suitable for continuous dosing to drinking water systems, but is suitable for disinfections.

APPLICATIONS INCLUDE

Situations in which MICROCHEM M381 could be used, include:-

  • If there are time constraints for tank isolation (hotels, leisure centres, etc.)
  • If access to outlets is restricted (secure areas, multi tenant buildings, etc.)
  • If the use of chlorine disinfectant would be an issue (with chlorine altering the taste of food)
