Biological treatment of indoor air for VOC removal: Potential and challenges

The impact of greening systems on building energy performance: A literature review

“…Therefore, the importance of indoor air quality (IAQ) is growing due to its direct influence on human's health and productivity. Around 25% of US citizens suffer from poor IAQ either in their workplace or at home [66]. In Australia, unhealthy indoor air have been posed considerable finances around $12 billion annually due to workers absenteeism, less productivity and medical costs [67].…”

Toluene, Methanol and Benzaldehyde Removal from Gas Streams by Adsorption onto Natural Clay and Faujasite-Y type Zeolite

“…The percentages of sand, silt and clay in the FS clay sample were measured on bulk sediment, using a laser diffraction particle analyser. Samples were dispersed in 100 cm 3 of deionised water and disaggregated under stirring using ultrasonic waves output of 1000 kW, and a vibration giving time of 10 min. 36 Mineralogical composition of natural clay was determined by powder X-ray diffraction analysis (XRD) using X'Pert PRO Philips diffractometer (Philips Japan, Ltd, Japan), equipped with CuKá radiation (λ= 1.5406 Å) at 40 kV and 40 mA.…”

Preliminary Acclimation Strategies for Successful Startup in Conventional Biofilters

“…The preliminary experiments were performed by adding 1 L of toluene or acetone to the bottles with a syringe. Each bottle septum was perforated 8,10,12,14,18, and 20 times with the syringe and possible leakage was determined by weighing every 12 hr. During these experiments, the Mininert valve was in the open position and the bottles were placed on an orbital shaker (Selecta).…”
