The B2 and B3 level Grease Trap Rooms at the JEM shopping centre in Jurong Singapore had terrible odour problems. The smell was so bad, you would walk inside, and immediately have to leave.
JEM (and their owner, Lendlease retail) had tried many solutions, the latest being a chemical spray / mister. Nothing was successful.
We installed just 1 unit of our Model UV SG7000T36 PRO Ozone Generators inside each of the Grease Trap Rooms, suspended from the ceiling in a custom built cage.
When they were turned on, within 8 hours, the odours were almost gone.
