For more than 12 months, the exhaust air around the pump house at Wilhelm-Henze-Weg in Laatzen as well as the sewer shaft are enriched with our active substance SinoAir®. The measurement results and the interview with the residents raise hope that with the use of SinoAir® an effective and permanent solution is found. The measurements show that with consequent follow-up care the malodor is not smellable for the residents anymore and therefore does not cause any further nuisance.
Furthermore, the amount of sulphuric acid in the waste water shafts could be significantly reduced.
During the remaining testing period, the needed dosage has to be determined and the concentration of the active substance needs to be adjusted to the pollution ratio.
