The RAMS-CALMET-CALPUFF modelling system has been used to simulate the odorous impacts from a paper-mill in an urban area located several kilometres away in a coastal mountainous area.

   Over the last years, episodes of citizens complaints due to malodours have been registered, with a potential origin in several pollution sources located inside and outside the city. A selection of episodes under anticyclonic conditions, with poor ventilation in general and continuous changes of stability and wind during the day, has been simulated.

   The SM100i uses fixed orifice dilution control and therefore requires minimal re-calibration. However standard, annual re calibration should be performed. As a new service for their clients, the company Scentroid offers their new maintenance Service that includes disassemble and ultrasonic cleaning, re-assembly and replacement of all tubing and seals and a final re-calibration.

   The parts that should be sent for calibration are the dilution System of SM100 (or the retrofit Kit for SM100i), the Face Mask, the carbon filter with the tank valve and all the plates. The annual service and recalibration includes the following:
