Environmental Protection

The German Alpine Association (DAV) has been committed many years ago for the use of renewable energy - as a natural conversation organization.

 

The Section Neumarkt i. d. OPf. Of the DAV has taken the commitment to nature even further. 


With the nature of YOU and YOU

In the choice of building materials for the new Olpererhütte the values of the so-called grey energy and recyclability have been considered. 

 

So-called grey energy is that which is required for the production of the building material. 

  • Wood is as a renewable raw material CO2 neutral thus contribute to climate protection 
  • Photovoltaic systems and a rapeseed oil-powered block heating works are producing the necessary electricity and hot water 
  • The wastewater is treated in a fully biological sewage treatment plant with membrane filtration

Functional description of the wastewater treatment
 
The wastewater flows to the treatment plant of Olpererhütte and will screen in a first step by 6 mm. Thereafter, the screened wastewater runs into a lifting station, from where it will pump into the first fluidized bed reactor. Kitchen wastewater will pretreat in a grease trap and separate in floated grease and settled sludge.
 
The biological treatment consists of three fluidized bed reactors connected in a cascade with each other. The fluidized bed reactors contain growth bodies on which microorganisms colonize (immobilize). Oxygen will supply via membrane plate from the container bottom in the wastewater.


 


The biologically treated wastewater flows afterwards from the fluidized bed reactors into the secondary clarifier. Here the material from the biological stages will settle as secondary sludge. The sludge will feed via two pressure lines to a bag filter for storage. The floating sludge will pump also in the bag filter.


 


The treated effluent leaves the secondary clarification via a dip tube, which prevents the escape of the growth bodies, and runs into the infiltration system.
