Application of nanotechnology in removal of NAPLs from contaminated aquifers: a source clean-up experimental studySpringer Science and Business Media LLC - Tập 20 - Trang 427-433 - 2018
Tannaz Pak, Nathaly Lopes Archilha, Raaid Al-Imari
This work investigates the removal of non-aqueous phase liquids (NAPLs) from groundwater resources using nanotechnology. We present results of a series of multiphase fluid displacement experiments conducted in a naturally occurring sandstone rock. These experiments involve injection of an aqueous suspension of silica nanoparticles to remove a trapped NAPL phase. Specifically, the effect of nanopar...... hiện toàn bộ
Tanning performance and environmental effects of nanosized graphene oxide tanning agentSpringer Science and Business Media LLC - Tập 18 - Trang 1997-2006 - 2016
Shenghua Lv, Qingfang Zhou, Ying Li, Yaya He, Haoran Zhao, Shiyu Sun
Nanosized graphene oxide (GO) with multiple oxygen-containing groups was prepared as a leather tanning agent. Leather tanned with 0.4 % GO can meet the shrinkage temperature (T
s) and mechanical properties required for the commercial leather products. The GO nano-tanning effluent had much lower pollution indexes, such as total nitrogen, total organic carbon, chemical oxygen...... hiện toàn bộ
Marginal abatement costs for GHG emissions in Canada: a shadow cost approachSpringer Science and Business Media LLC - Tập 25 - Trang 1323-1337 - 2022
Samuel Gamtessa, Monika Çule
This study approximates the marginal abatement costs (MACs) of reducing GHG emissions in Canada using the shadow cost approach. Utilizing industry level data, we are the first to offer Canadian estimates based on a Hyperbolic Output Distance Function (HODF) and the stochastic frontier estimation. Accounting for GHG emissions caused by energy consumption, we obtain an average shadow MAC of $130/t a...... hiện toàn bộ
Fluoride removal on Fe–Al-impregnated granular ceramic adsorbent from aqueous solutionSpringer Science and Business Media LLC - Tập 16 - Trang 609-617 - 2013
Nan Chen, Chuanping Feng, Miao Li
A novel Fe–Al-impregnated granular ceramic adsorbent has been developed for fluoride removal from aqueous solution. Batch experiments were performed to investigate the effect of contact time, initial pH, adsorbent dose, and the presence of competing anions on the adsorption of fluoride. More than 96 % removal of fluoride was achieved within 48 h from 10 mg/L initial fluoride solution at neutral pH...... hiện toàn bộ
Benchmarking in wastewater treatment plants: a tool to save operational costsSpringer Science and Business Media LLC - Tập 16 - Trang 149-161 - 2013
M. Molinos-Senante, F. Hernandez-Sancho, R. Sala-Garrido
The economics of wastewater management and treatment is the subject of growing interest by water agencies and wastewater treatment plant (WWTP) operators. Benchmarking procedures are useful tools to assess the performance of these facilities and help identify best practices. To estimate the efficiency scores for each input involved in the operation of WWTPs, a non-radial data envelopment analysis ...... hiện toàn bộ

Use phase and end-of-life modeling of biobased biodegradable plastics in life cycle assessment: a reviewSpringer Science and Business Media LLC - Tập 24 - Trang 3253-3272 - 2022
Katrin Molina-Besch
Due to the negative environmental impacts along the life cycle of fossil-based plastics, there is an increased interest in the development of biobased and biodegradable plastics. Especially, biodegradable bioplastics possess different material characteristics than fossil-based plastics and can therefore be expected to perform differently during the product use and in end-of-life (EOL) phases. Thus...... hiện toàn bộ
Water global recourse management through the use of microalgae addressed to sustainable developmentSpringer Science and Business Media LLC - Tập 13 - Trang 431-445 - 2010
Armen B. Avagyan
Cost advantages are the primary drivers for water resource management friendly investments. Therefore, acceleration of sustainable development requires the implementation of new innovation approach. At present, preventative measures of algal bloom development are not achieving sustainable results and spread of the blue-green infection can reach catastrophic dimension. Our vision of water recourse ...... hiện toàn bộ
