Green remediation of As and Pb contaminated soil using cement-free clay-based stabilization/solidification

Autor: Lei Wang, Dong-Wan Cho, Daniel C.W. Tsang, Xinde Cao, Deyi Hou, Zhengtao Shen, Daniel S. Alessi, Yong Sik Ok, Chi Sun Poon

Publikováno v: Environment International, Vol 126, Iss , Pp 336-345 (2019)

Stabilization/solidification (S/S) is a low-cost and high-efficiency remediation method for contaminated soils, however, conventional cement-based S/S method has environmental constraints and sustainability concerns. This study proposes a low-carbon,

Co-thermochemical conversion of coffee grounds and nano Fe(III) oxides to fabricate metal-biochar for the simultaneous removal of Sb(V), Cd(II), and Ni(II) from water

Autor: Dong-Wan Cho, Jeong-Yun Jang, Youngwook Cheong, Gil-Jae Yim

Nano Fe(III) oxide (FO) was employed as an additive material for CO2-aided pyrolysis of spent coffee grounds (SCG) and its impacts on the syngas (H2 & CO) generation and biochar adsorption characteristics were examined. Amendment of FO led to 153 and

Evaluation of water quality change and sludge generation according to hydrogen peroxide treatment during lime neutralization

Autor: YoungWook Cheong, Dong-Wan Cho, Giljae Yim, Jeong-Yun Jang

This study investigated the effect of hydrogen peroxide treatment on the removal pH for Fe, Al, and Mn and sludge production in the lime neutralization process. In the laboratory, the AMD collected from the coal mine was oxidized with 5% H2O2, and th

Fabrication of PAC sludge-valorized biochars and their practical application to the remediation of methyl arsenic in wetlands

Autor: Jungho Ryu, Young-Soo Han, Dong-Wan Cho, So-Jeong Kim, Yong-Chan Cho, Chul-Min Chon, Joo Sung Ahn, In-Hyun Nam

This study aims to mitigate As pollution in wetlands by using biochar composites, which are a byproduct of valorizing drinking water treatment sludge (i.e., polyaluminum chloride (PAC) sludge). PAC sludge produced when PAC is used as a coagulant cont
