Absorption of a mixture of volatile organic compounds (VOCs) in aqueous solutions of soluble cutting oil

Effect of saponins on n-hexane removal in biotrickling filters

“…VOCs are harmful to human health, ecosystems, atmosphere, and have become a cause of concern worldwide (Balasubramanian et al, 2012). In response to the rising concerns about their harm and the increasingly strict government regulations, many VOCs treatment technologies have surfaced in recent years (Lalanne et al, 2008). Biological air treatment systems have emerged as effective low-cost alternatives to the more traditional and energy-intensive methods such as incineration, absorption, condensation, and adsorption (Santos et al, 2007).…”

Estimating the cellular maintenance coefficient and its use in the design of two-phase partitioning bioscrubbers

“…Recently, many other researchers have begun to apply the concept of the TPPB to the treatment of various VOCs and other contaminants [10][11][12][13][14][15]. Although this research has generally been successful, encouraging TPPBs to be applied to other target molecules, the approach has largely been heuristic with no general strategies being proposed to aid in, for example, solvent selection, specification of organic phase fraction, operating conditions, etc.…”

The effect of starvation periods on the performance of a two-liquid-phase mixed tank bioreactor for removal of n-hexane from air streams

“…Arriaga et al [5] reported large improvement in the elimination capacity of a biofilter after use of silicone oil. Lalanne et al [6] reported an improvement in elimination capacity of VOCS from 12% to 36% on adding soluble cutting oil to a bioreactor. In this research the effect of starvation periods on the performance of a silicone oil-containing bioreactor was compared with that of a control bioreactor.…”
