Although our systems clean up to 99.9% of bacteria in the waste water, a danger of remaining bacteria concentrations may persist.

Regulatory requirements for sensitive areas are usually that emissions should contain less than 1,000 TCB/100 ml cleaned waste water (TCB: thermo-tolerant coliform bacteria). As the amount of bacteria may vary significantly from house to house, this may be difficult to guarantee when using traditional solutions such as UV radiation or Leca filters. Some of the traditional technologies also require a high level of maintenance.

Hydrogen peroxide (H2O2)

In order to meet regulatory requirements for the maximum amount of bacteria we use hydrogen peroxide (H2O2) as a disinfection agent in a native hygienising tank which is fitted to the outflow of the treatment system.

Hydrogen peroxide in the concentration we use is an environmentally friendly agent which decomposes spontaneously into water and oxygen. The free oxygen radicals which are created oxidise the bacteria and the cleaned waste water is thereby disinfected in a controlled way.
