Abstract
The present study examined the biodegradation rate of benzene vapors in a two phase stirred tank bioreactor by a bacterial consortium obtained from wastewater of an oil industry refinery house. Initially, the ability of the microbial consortium for degrading benzene was evaluated before running the bioreactor. The gaseous samples from inlet and o...... hiện toàn bộ
Evaluation of iron and manganese-coated pumice application for the removal of as(v) from aqueous solutions Tập 9 - Trang 1-9 - 2012
Leila Babaie Far, Bubak Souri, Masoumeh Heidari, Roshan Khoshnavazi
Arsenic contamination of water has been recognized as a serious environmental issue and there are reports on its epidemiological problems to human health. The objective of this study was to evaluate the performances of iron-coated pumice and manganese-coated pumice as the adsorbents for removing arsenate from aqueous solutions. The effect of various parameters such as adsorbent dose, contact time,...... hiện toàn bộ
Influence of liquid and gas flow rates on sulfuric acid mist removal from air by packed bed tower Tập 9 - Trang 1-7 - 2012
Mohammad Javad Jafari, Roohollah Ghasemi, Yadollah Mehrabi, Reza Ahmad Yazdanbakhsh, Majid Hajibabaei
The possible emission of sulfuric acid mists from a laboratory scale, counter-current packed bed tower operated with a caustic scrubbing solution was studied. Acid mists were applied through a local exhaust hood. The emissions from the packed bed tower were monitored in three different categories of gas flow rate as well as three liquid flow rates, while other influencing parameters were kept almo...... hiện toàn bộ

Tea is one of the most common drinks in all over the world. Rapid urbanization and industrialization in recent decades has increased heavy metals in tea and other foods. In this research, heavy metal contents such as lead (Pb), cadmium (Cd) and arsenic (As) were determined in 105 black tea samples cultivated in Guilan and Mazandaran Provinces in north of Iran and their tea infusions. The amount of...... hiện toàn bộ
Preliminary study on optimization of pH, oxidant and catalyst dose for high COD content: solar parabolic trough collector Tập 10 - Trang 1-10 - 2013
Chandan Singh, Rubina Chaudhary, Kavita Gandhi
In the present study, solar photocatalytic oxidation has been investigated through laboratory experiments as an alternative to conventional secondary treatment for the organic content reduction of high COD wastewater. Experiments have been performed on synthetic high COD wastewater for solar photocatalytic oxidation using a parabolic trough reactor. Parameters affecting the oxidation of organics h...... hiện toàn bộ
