Bad Hersfeld Hospital
Use of the WFF vortex fine filter
Bad Hersfeld, Germany | 2008
The hospital in Bad Hersfeld has long experience in rainwater utilisation - an ecological commitment that saved about € 13,500 in 2007.
For 2008, pond and irrigation were estimated at 40 m³ and toilet flushing at 1,801 m³ per year. In addition, 1,107 m³ of softened drinking water could be saved for cooling vacuum pumps. Thus, the rainwater utilisation had a volume of 2,948 m³.
The rainwater storage tank built in 1995 is made of steel, the additional battery installed in 2001 consists of eight plastic tanks. Both cisterns are connected to each other and are fed with rainwater in parallel. A vortex fine filter from Wisy AG is installed in front of each storage tank. Particles are automatically flushed into the wastewater pipe without clogging the filter or having to be disposed of. This results in high efficiency and a long service life, i.e. safe and effective operation.
- Savings: As of 2007: € 5,436 for drinking water plus € 450 saved precipitation fee, together € 5,886 per year.
