We have been facing up to our own responsibility for some time now

"We can purify that best ourselves- our slogan for decades!"

is what we said with regard to our wastewater.

We have been operating our own process water treatment plant (PWA) since 1986. This enables us to feed water that has been subjected to chemical/physical pre-treatment into the Hof/Saale regional sewage treatment plant for complete biological treatment. The prepurification removes over 99% of hazardous substances and 90% of the polluting load from the water. This type of pre-treatment is characterised by great flexibility, even with heavy fluctuations in volume and quality of the wastewater.
