In a study conducted by Eurofins Ecotoxicologie France, FINEAMIN 06 has proved to be readily biodegradable, with a biodegradability rate of 90% after 28 days of test. To be considered as ready biodegradable, a product (mainly, a pure substance) must show a biodegradation rate of at least 70% in the 10-day interval which has to fall within the 28 (firsts) days of the test.
FINEAMIN 06, our well-known for its efficiency, industrial water treatment mixture of filming amines and cleaning polymers, passed the ready biodegradable level in the first 7 days, the degradation percentage stabilizing itself to a 90% rate towards the end of the testing period.
EVALUATION OF READY BIODEGRADABILITY: DISSOLVED ORGANIC CARBON DIE-AWAY FOLLOWING THE OECD 301 A GUIDELINE Test report n° 20FER6-1175 – 2020/12/09
The assay was conducted by including these following preparations:
- The tested sample with a concentration of 15 mg/L of DOC (2 flasks),
- A control assay of the seeding (blank) (2 flasks),
- An assay with reference substance with a biodegradability rate superior to 90% (sodium acetate at 15 mg/L of DOC),
- An assay with the control of inhibition containing the tested sample and the reference substance at tested concentrations.
Several assays were under aeration stirring at 22 +/- 2°C.
A mineral medium was prepared using ultra-pure water. Reference substance: sodium acetate.
A bacterial inoculum was prepared using pretreated and exactly quantified activated sludge from Maxeville’s water treatment plant (France) dealing primarily with domestic waste water (98%).
FINEAMIN 06 was added directly in assay bottles containing 1L mineral medium and activated sludge with a pH of 7.4.
