Resumen de Particularities of indoor air biotreatment
Cécile Hort, Angela Tatiana Luengas Muñoz
Conventional techniques in the treatment of gaseous effluents that have been developed in recent years for the industry are not suitable for the problem of indoor air purification. The indoor air is characterized by the presence of a wide variety of contaminants, with different physicochemical properties, at very low concentrations that sometimes are higher than the limits or guideline values corresponding to an acceptable health risk. The phenomena involved in the existing treatment processes today are affected by these specificities of the indoor air. Accordingly, nowadays, coupling the biotreatments for the reduction of the indoor air chemical pollution with conventional technologies has emerged as a promising technological option for treating air in indoor environments. In fact, botanical biofiltration is easy to implement and has a high removal efficiency for a large range of chemical compounds. Botanical purification by potted plants on the other hand, involves a more complex process where plant’s root system, leaves, and microorganisms in the growth medium play a major role in the removal of contaminants from the gaseous phase.
