Water treatment

Activated Lignite HOK is produced from Rhenish lignite by activation in a rotary hearth furnace, which has given the product its name, viz. HOK. Production, distributionand logistics are based on a consistently implementedquality system in compliance with DIN-ISO 9001.

HOK – the low-cost adsorbent and catalyst for environmental technology

What is HOK about?

Activated Lignite HOK is produced on the basis of Rhenish lignite in the so-called rotary hearth furnace process. The special properties of Rhenish lignite, coupled with the activation conditions in the rotary hearth furnace, yield Activated Lignite HOK which has been used for many years as low-cost adsorption and filter agent in the most varied of applications in waste gas and effluent treatment.
