Single factorial experimental design for decolorizing anaerobically treated distillery spent wash using cladosporium cladosporioides
International Journal of Environmental Science and Technology - Tập 8 - Trang 97-106 - 2010
R. Ravikumar, N. S. Vasanthi, K. Saravanan
This study presents the standardization of nutrient concentration, pH and temperature required to decolorize the anerobically treated distillery spent wash using the fungus Cladosporium cladosporioides. Experiments were carried out to measure the decolorization of distillery spent wash effluent and it was found to be effective in acidic environment. From the results it was observed that a maximum ...... hiện toàn bộ
Interactive behavior of cadmium ions onto polyethylene microplastics in aquatic system
International Journal of Environmental Science and Technology - - 2024
D. M. Reddy Prasad, B. S. Naveen Prasad, R. Senthilkumar, K. Saravana Kumar, S. Manickkam
Microplastics and heavy metals are two different classes of pollutants that are often present in aquatic systems. However, the interaction between these two pollutants is poorly understood in freshwater systems. This research has examined the sorption of cadmium(II) ions onto polyethylene microplastic (PEMP) under freshwater conditions. The scanning electron microscope, X-ray diffraction, and Four...... hiện toàn bộ
Effect of soil amendments on phytoextraction potential of Brassica juncea growing on sewage sludge
International Journal of Environmental Science and Technology - Tập 9 - Trang 559-564 - 2012
G. Dede, S. Ozdemir, O. Hulusi Dede
A pot experiment was conducted to investigate the influence of elemental sulfur, gypsum and chelating agent (Ethylenediaminetetraacetic acid) on copper, zinc, nickel, cadmium, chromium and lead uptake by Brassica juncea from sewage sludge. Addition of sulphur acidified the sludge, which caused the pH decrease to 5.4 with an initial pH 6.7. The shoot and root biomass were increased with sulfur addi...... hiện toàn bộ

Kiểm soát tiềm năng hình thành sản phẩm phụ khử trùng bằng phương pháp đông tụ nâng cao Dịch bởi AI
International Journal of Environmental Science and Technology - Tập 2 - Trang 335-342 - 2005
A. Mesdaghinia, M. T. Rafiee, F. Vaezi, A. Mahvi, A. Torabian, A. Ghasri
Các thí nghiệm jar-test đã được tiến hành để nghiên cứu hiệu quả của quá trình đông tụ nâng cao trong việc loại bỏ các sản phẩm phụ khử trùng (DBPs) từ sông Zayandehrud tại tỉnh Isfahan - khu vực trung tâm của Iran - vào năm 2004. Trong nghiên cứu này, việc loại bỏ các hạt lơ lửng và keo cũng như chất hữu cơ tự nhiên (NOM) với các liều lượng đông tụ và pH đông tụ khác nhau đã được đánh giá thông q...... hiện toàn bộ

Application of raw Vigna subterranean husks as novel sorbent for abstraction of petroleum from contaminated waters
International Journal of Environmental Science and Technology - Tập 19 - Trang 4869-4882 - 2021
I. C. Ogbu, C. N. Ibeto, C. O. B. Okoye
The potential of raw V. subterranean husks (RVSH) as a novel natural sorbent, and an environmentally friendly and low-cost product for the cleanup of petroleum from contaminated waters was investigated. Characterization of the sorbent was accomplished with scanning electron microscope (SEM), Fourier transform infrared (FTIR), Brunauer–Emmett–Teller (BET) surface area analysis and thermogravimetric...... hiện toàn bộ
Comparison between continuous and intermittent ozonation for remediation of soils contaminated with polycyclic aromatic hydrocarbons
International Journal of Environmental Science and Technology - Tập 12 - Trang 3457-3462 - 2015
J. Wu, Y. Jiang, Z. Ye, M. Prabhakar, R. Yu, H. Zhou
Continuous ozonation can inactivate indigenous microbes due to the disinfection capability of ozone, which may affect subsequent bioremediation of soils. This study investigated the efficiency of removing polycyclic aromatic hydrocarbons from soils using intermittent ozonation technique, where ozone was sparged through the soil column every alternate day, resulting in shorter ozonation time for e...... hiện toàn bộ
Groundwater potential mapping with geographical information techniques for a sustainable environment in Haliliye Basin, Turkey
International Journal of Environmental Science and Technology - Tập 19 - Trang 10337-10352 - 2021
V. Aslan, M. F. Dilekoğlu
In order to develop and manage groundwater resources sustainably, it is necessary to make precise quantitative assessments based on scientific principles as well as modern techniques. Groundwater feeding is an important process for the management of surface water resources as well as underground water resources. In this study, the application of analytical hierarchy process on geographical–spatial...... hiện toàn bộ

Anaerobic production of valeric acid from crude glycerol via chain elongation
International Journal of Environmental Science and Technology - Tập 17 - Trang 1847-1858 - 2019
S. T. S. Veras, W. A. Cavalcante, T. A. Gehring, A. R. Ribeiro, T. J. T. Ferreira, M. T. Kato, P. Rojas-Ojeda, J. L. Sanz-Martin, R. C. Leitão
Glycerol from biodiesel production was used as a substrate for valerate production in a 13.1-L anaerobic filter with an open microbiome. Ethanol at 15% of the influent chemical oxygen demand was supplemented as an additional electron donor source. The 114-day experimental period was divided in three phases which included initial adaptation phase, external sludge addition from a caproic acid produc...... hiện toàn bộ
