Variation of the Gravimetric Composition of Landfilled Municipal Solid Waste Over the Time in a Developing CountrySpringer Science and Business Media LLC - Tập 16 - Trang 1-15 - 2022
Cíntia Minori Takeda, Mariane Alves de Godoy Leme, Diego Costa Romeiro, Kennedy Gabriel Silva, Miriam Gonçalves Miguel
In Brazil, information related to the physical and chemical characteristics of landfilled municipal solid waste (MSW) to evaluate their potential uses as a secondary raw material or source of energy is lacking. Thus, this study aims to determine the gravimetric composition of landfilled MSW aged 24 years (MSW-24), which were excavated from Delta A Sanitary Landfill, located in the municipality of ...... hiện toàn bộ
Investigating the Effects of Copper Slag and Silica Fume on Durability, Strength, and Workability of ConcreteSpringer Science and Business Media LLC - - 2019
Ravanbakhsh Shirdam, Mahdiyeh Amini, Nematollah Bakhshi
Workability, strength, durability, economic considerations, and attention to sustainable development issues are some crucial factors in designing an appropriate mix. The use of copper slag as a partial replacement of cement is an effective method of pollution reduction and conservation of resources, since it reduces cement use. In addition, silica fume is used in combination with copper slag to ma...... hiện toàn bộ
Decadal Changes in Atmospheric Methane Emissions in the Eastern Himalayan Region: Source Apportionment and Impact AssessmentSpringer Science and Business Media LLC - Tập 17 - Trang 1-23 - 2022

Methane (CH4), the second-largest greenhouse gas in terms of radiative forcing, is on the rise in the Eastern Himalayan region (EHR), as indicated by multiple datasets (CAMS ~ 0.087 Tg Yr−1, EDGAR v4.3.2 ~ 0.11 Tg Yr−1, and RCP8.5 ~ 0.16 Tg Yr−1). We found that the CH4 trend over the EHR is stronger than the global trend due to increased emissions from anthropogenic sources. From 1990 to 2016, CH4...... hiện toàn bộ
Decomposition of a High-Concentration Hydrazine in Wastewater from A Chemical Decontamination Process of A Nuclear FacilitySpringer Science and Business Media LLC - Tập 14 - Trang 385-391 - 2020

Hydrazine (N2H4) can injure lungs, liver, kidney, and central nervous system, and it may be carcinogenic to humans. It is used for a chemical decontamination process (HyBRID) of a nuclear facility. After the decontamination process, wastewater containing a high concentration of hydrazine is generated. Thus, it is necessary to remove hydrazine from the wastewater by a safe level. The decomposition ...... hiện toàn bộ
Challenges and Operational Strategies to Achieve Partial Nitrification in Biological Wastewater Treatment: A ReviewSpringer Science and Business Media LLC - - 2024
Alice Chiapetti Bolsan, Camila Ester Hollas, Heloisa Campeão Rodrigues, Jadiane Paola Cavaler, Ana Claudia Lazaroto, Naiana Cristine Gabiatti, Marcelo Bortoli, Gracielle Johann, Fabiane Goldschimidt Antes, Airton Kunz, Thiago Edwiges, Marina Celant De Prá
Partial nitritation is a promising technology for wastewater treatment systems and, in symbiosis with other nitrogen removal approaches (i.e., Anammox bacteria), is attractive for reducing costs compared to conventional technologies. However, the intrinsic problems related to the different characteristics of the effluent induce unstable process conditions, including the subsequent accumulation of ...... hiện toàn bộ
Biodegradation of Triphenylmethane Dyes by Non-white Rot Fungus Penicillium simplicissimum: Enzymatic and Toxicity StudiesSpringer Science and Business Media LLC - Tập 13 - Trang 273-282 - 2019
Si Hui Chen, Yuen Lin Cheow, Si Ling Ng, Adeline Su Yien Ting
A non-white rot fungus, Penicillium simplicissimum (isolate 10), was investigated for its biodegradation activities towards toxic triphenylmethane (TPM) dyes such as Crystal Violet (CV), Methyl Violet (MV), Malachite Green (MG), and Cotton Blue (CB). High decolorization efficiencies of 98.7, 97.5, 97.1, and 96.1% were observed for CV, MV, MG, and CB, respectively, within 2 h of incubation in the d...... hiện toàn bộ
