Journal ArticleDOI
Recent Applications of Electrocoagulation in Treatment of Water and Wastewater—A Review
TL;DR: In this article, the authors present an overview of the optimum process conditions (treatment times, current densities, and initial pH) and removal efficiencies (mostly high) achieved for the EC applications discussed.
Journal ArticleDOI
Metakaolin geopolymer characterization and application for ammonium removal from model solutions and landfill leachate

TL;DR: In this paper, a metakaolin-based geopolymer was applied to remove ammonium (NH 4 + ) from model solutions and landfill leachate, achieving an NH 4 + removal capacity of 21.07mgg − 1 which was 46% higher than the capacity of the reference clinoptilolite-heulandite zeolite.
Journal ArticleDOI
Simultaneous removal of Ni(II), As(III), and Sb(III) from spiked mine effluent with metakaolin and blast-furnace-slag geopolymers.

TL;DR: The results indicate that geopolymer technology could offer a simple and effective way to turn blast-furnace slag to an effective sorbent with a specific utilization prospect in the mining industry.
Journal ArticleDOI
Sulphate removal over barium-modified blast-furnace-slag geopolymer
Hanna Runtti,Tero Luukkonen,Mikko Niskanen,Sari Tuomikoski,Teija Kangas,Pekka Tynjälä,Emma-Tuulia Tolonen,Emma-Tuulia Tolonen,Minna Sarkkinen,Kimmo Kemppainen,Jaakko Rämö,Ulla Lassi,Ulla Lassi +12 more
TL;DR: The novel modification method of geopolymer material proved to be technically suitable in achieving extremely low concentrations of SO4(2-) (<2mgL(-1)) in mine effluents and the Sips model showed the best fit.
Journal ArticleDOI
Comparison of organic peracids in wastewater treatment: Disinfection, oxidation and corrosion
TL;DR: Peracids synthesized, compared and compared in laboratory batch experiments for the inactivation of Escherichia coli and enterococci in tertiary wastewater, oxidation of bisphenol-A and for corrosive properties revealed PFA to be a more potent disinfectant than PAA or PPA.
