Improving air quality through photocatalytic oxidation (PCO)
Air pollution has become a major problem worldwide. Not only outdoors, also the indoor quality in buildings is becoming rather poor. LMDC is studying degradation by photocatalysis, a more natural way of preventing air pollution, of some primal indoor air pollutants like nitrogen oxides (NOx) and certain volatile organic compounds (VOCs) such as formaldehyde (CH2O), benzene, toluene, ethylbenzene and xylenes (BTEX).
By donating instruments and knowledge for this innovating project, Bronkhorst will contribute in LMDCs research towards a cleaner indoor environment. The Bronkhorst mass flow meters and controllers will be used in the reseach set-up to inject polluted and humidified air into a reactor containing photocatalytic material. Because of the low pollution levels, the mass flow controllers have to be very accurate. For this experimental set-up LMDC will use a Bronkhorst mini CORI-FLOW ML120 Coriolis flow meter, a CEM (Controlled Evaporation and Mixing system), an E-8000 read-out and control unit and a LOW-dP-FLOW thermal mass flow meter.
