Lantmännen Biorefineries offers Agrosustanol 100 made from biodegradable bioethanol as an external carbon source for the denitrification step of wastewater treatment plants' nitrogen removal.

Agrosustanol 100 has a high proportion of g COD/g ethanol and a high proportion of readily available carbon, resulting in a high denitrification rate and low anoxic volume. Agrosustanol 100 has a short adaptation period, does not contribute to heavy sludge production and has a marginal impact on the existing bacterial composition. Agrosustanol can be used in both the pre- and post-denitrification steps but also in the SBR step. The use of n-butanol as denaturant contributes positively to the COD content of the carbon source.

Agrosustanol 100 is sold in bulk by truck.
