<p class="JIPIAbstrakKeywords">A number of diseases have been stigmatized as a side effect smoking and its smoke. Reducing the dangers by capturing radioactive substances from cigarette smoke is one way to reduce or level danger. This study aims make filter made bidara leaf powder bind free radicals in Bidara with PEG solution was mixed stirred until homogeneous variations mass 0.7 grams,...

Biodegradation of methyl tert-butyl ether (MTBE) vapors by cometabolism with gaseous hexane (n-hexane > 95%) was investigated using Pseudomonas aeruginosa utilizing short chain aliphatic hydrocarbon (C(5)-C(8)). Kinetic batch experiments showed that MTBE was degraded even when hexane was completely exhausted with a cometabolic coefficient of 1.06 ± 0.16 mg MTBE mg hexane(-1). Intermediate tert-...

The purpose of this research was to neutralize livestock-generated ammonia by using biofilters packed with inexpensive inorganic and organic packing material combined with multicultural microbial load at typical ambient temperatures. Peat and inorganic supporting materials were used as biofiltration matrix packed in a perfusion column through which gas was transfused. Results show the ammonia r...

In this study, a mathematical model is proposed which incorporates mass transfer process and biofilm reactions in trickle bed air biofilter (TBAB). The model consists of a set of mass balance equations for isopropyl alcohol (IPA), acetone (ACE) and oxygen within the bulk gas phase and within the biofilm. These set of ordinary differential equations are converted into non-dimensionalised form an...

Abstract The physical/chemical abatement of gas pollutants creates many technical problems, is costly and entails significant environmental impacts. Biological purification off-gases a cheap ecologically safe way neutralization pollutants. Despite the recent advances, main technological challenge nowadays volatile organic compounds (VOCs) hydrophobic character due to their low solubility in wat...

Reducing the pressure drop in biofilters is important for reduction of energy consumption these devices. Usually, increases with time due to biomass growth within packing material. The aim this study was evaluate aerodynamic processes a laboratory-scale wavy lamellar (WL) plate-type biofilter equipped capillary system humidifying material designed consisted polymer plates (WPP) vertically arran...
