As in most chemical plants, the greater part
of the water used is required for cooling. Except for a moderate
temperature increase, this water is returned to the river in a
nearly unpolluted condition.
Biological Waste Water Treatment
Billions of Micro-organisms Help us Treat Waste Water
This cleaning process, which constantly takes place in nature, occurs under optimised
conditions in our waste water treatment plant, which comprises
two BIOHOCH® reactors.
The waste water treatment occurs there via so-called
activated sludge, a naturally developed community of aquatic
organisms: bacteria, unicellular and multicellular organisms,
which are specialised on the respective nutrient supplies
(= pollutants) in industrial waste water.

A Real Power Pack
Despite their low space and energy requirements, the BIOHOCH®
reactors are real power packs. Their daily purification
capacity is approximately 110,000 population equivalents (PE).
The term PE describes the average, biologically degradable
pollutant quantity (BSB5) which is produced daily
by every member of the population.
