Water disinection is o great importance in all buildings

with drinking water consumption, and particularly in

buildings that supply shower and bathing acilities. Water

disinection is also essential in applications where water

mist is sprayed into the air, or instance cooling towers

and evaporative condensers.

Grundos Oxiperm Pro system ensures sae, clean water

to all its end users in buildings such as:

Hotels Hospitals

Sportsandswimmingfacilities

Fitnesscentres

Wellnessresorts

Residentialbuildings

The problemNaturally,thewaterwedrinkandshowerinhastobe

cleanifwearetostayhealthy.Unfortunately,oneof

the most widespread health hazards in drinking water

installations worldwide is connected to exceptionally

resistantbacterialegionella.

Legionella exist mainly in hot water systems with a

lowowrate,areasofstagnationorbadlyserviced

hot water tanks. A layer o slime in the water pipes

OXIPERM PROtHe Benefits

The chemistry o great benetsThe Oxiperm Pro system uses chlorine dioxide or

the disinection o water. This particular chemical

compoundpresentsanumberofadvantagesthat

Example o calculation o maximum hourly

fow rate in a 200-bed hotel

Annual water consumption: Qyear=180m3/bed/year

Consumptionperiod:365days/year

Averagedailyconsumption:Qavg=180/365=0,5m3/bed/day

Dayfactor:fd = 1,5

Maximum daily fow rate: Q max = 0,5 x 1,5 = 0,75 m3/bed/day

Peak actor: p = 4

Maximum hourly fow rate per unit: Qpeak=0,75x4/24=0,125m3/bed/hNumberofbeds:n=200

Maximum hourly fow rate or the whole hotel: Qpeak = 200 x 0,125 = 25

m3/h(hotandcoldwater)

Maximum hourly fow rate or the whole hotel: Qpeak = 25 x 0,4 = 10 m3/h
