Hermanninsaari sewage plant

At a sewage plant in Porvoo, Desinfinator Aero 1000 air cleaning modules removed all hydrogen sulphide and the odour problems from the air.

At the installation location, the level of hydrogen sulphide was 81 ppm before installation of the units from Desinfinator. Some 24 hrs after the installation of the units from Desinfinator, the level of hydrogen sulphide was down to 0 ppm (measured with a measurement device from the company Dräger, type: Dräger 700 H2S) and the odour was almost completely removed as well.

The man in charge of the sewage plant, Mr Henry Åkerman, is very happy with the results.
