Winning the confidence of customers with Downflow Anaerobic Carrier System DACS®

With innovative technology and tailor-made wastewater treatment plants, Aqana makes a difference in the industrial wastewater treatment market.

Aqana’s technology makes it possible to make the purification of wastewater a sustainable process. With the DACS® treatment, a relatively large amount of biomass is held inside of the carriers within the anaerobic system – resulting in the effective conversion of the organic material in the wastewater into biogas.

DACS® eliminates the expensive necessity of granular sludge and by that manages to provide a reliable anaerobic system that guarantees continuous operation regardless of changes in flow and organic load. Thanks to this innovation the retention of the biomass is no longer limited by the flow velocity inside the reactor!

Aqana DACS® works efficiently with other wastewater treatment configurations.

Tangible benefits for your company and the environment


Experience solutions that guarantee operational reliability even with fluctuating composition of the wastewater.


Reduce your OPEX with a system that consumes less chemicals and ensures uninterrupted green energy source at your WWTP.


Meet the most stringent environmental regulations with ease. Preserve water for future generations.
