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
Combined advanced oxidation and biological treatment of tannery effluentSpringer Science and Business Media LLC - - 2011

During leather processing in tanneries, considerable amount of wastes with organic and inorganic pollutants are generated. For removal of these pollutants and recovery of water, biological treatment methods and reverse osmosis (RO) based membrane technologies are adopted. While recovering water from treated tannery effluent using RO membranes, presence of residual organics, dye molecules, and othe...... 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
Process Intensification and Integration: an assessmentSpringer Science and Business Media LLC - Tập 15 - Trang 417-422 - 2013
Jiří Jaromír Klemeš, Petar Sabev Varbanov
A considerable number of studies have been performed for improving the efficiency of production processes, of energy supply and utilisation, while reducing emissions of greenhouse gases, volatile organic compounds and other pollutants. This has been a very important task which this journal has been targeting. As a response to these industrial and societal requirements considerable research effort ...... 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
