Sanitary landfill odor control experience using organic biocatalysts and field olfactometry measurement

le .

Quintero   The sanitary landfill, located in the city of Pereira, Risaralda, Colombia, is operated by the company Atesa de Occidente S.A ESP, here the disposal of waste from department of Risaralda, some municipalities of Caldas and Norte del Valle del Cauda is carried out, it´s receiving 800 Tons/day, causing impacts to the environment by the emission of offensive gases and odors, causing problems to community.

   In Colombia, the offensive odour problem, is regulated with the Resolution 1541 of 2013, define the levels of inmission, according to the generating activities, carry to landfill to take measures to reduce, and to quantify odors too.

Analysis of odour episodes through dispersion modelling, field olfactometry and citizens’ complaints near a paper-mill

le .

Valdenebro   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.

Scentroid launches an annual re-calibration service for SM100 and SM100i olfactometers

le .

scentroid sm100 kit   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:
