Introduction
Electrocoagulation-flotation
Currently I'm focussing on tubular coaxial electrocoagulation reactor. With it uniform electrical field it is highly suitable to be applied for electrochemical process to treat waste water and beyond.

Electrocoagulation (EC) is a promising compact alternative technology, despite its viability in municipal wastewater treatment (MWWT) is currently challenged by its energy-intensive and batch-mode operation. This study introduces an innovative continuous electrocoagulation flotation (ECF) design for MWWT. ECF shows promising pollutant removal effic...
The low energy requirements to grow microalgae combined with the very fast reproduction gives microalgae unique abilities to utilize them for industrial and environmental applications. However, harvesting these algae still remains energy consuming and, as a consequence, expensive. In this work a new electro-coagulation-flotation setup with a tubula...
Hydrophobic deep eutectic solvents were used for the first time for the removal of metal ions from non-buffered water. It was shown that the extraction occurs via an ion exchange mechanism in which all transition metal ions could be extracted with high distribution coefficients, even for high Co²⁺ concentrations and low DES/water mass ratios. Maxim...

Aqueous waste streams of the metallurgical industry often contain considerable concentrations of metal salts. Previous research showed that the metal chloride salts of zinc(ii), manganese(ii) and iron(iii) can be recovered by solvent extraction using a sustainable and renewable fatty acid based ionic liquid as the extractant. In this paper, the ext...
In this work a two coaxial nozzles configuration is used to investigate whether electro hydrodynamic atomization of an ionic liquid in combination with an aqueous metal salt solution could enhance the removal of metal salts. The technique was evaluated for the removal of manganese (II), cobalt (II) calcium and sodium chloride. Good metal salt extra...
This work describes for the first time a continuous process for selective metal extraction with an ionic liquid (IL) at room temperature. The hydrophobic fatty acid based IL tetraoctylphosphonium oleate ([P8888][oleate]) was specifically chosen for its low viscosity and high selectivity towards transition metals. Applying [P8888][oleate] for contin...
Ionic liquids (ILs) have been presented as suitable candidates for metal extraction in the hydrometallurgy. It has already been proven that they have an adjustable selectivity towardsmetal ions. However, industrial applications of ILs are often limited due to their high price. Therefore, regeneration and reuse of ILs is necessary. In this study the...
The solvent extraction behaviour of a series of metal ions (Li+, Na+, K+, Mg2+, Ca2+, Mn2+, Fe3+, Co2+, Ni2+, Cu2+, Zn2+, In3+, La3+, Nd3+, Sm3+, Dy3+, Er3+, Yb3+) from an aqueous chloride feed solution by the non-fluorinated fatty-acid-based ionic liquid (IL) tetraoctylphosphonium oleate [P8888][oleate] has been investigated as a function of the p...
In this paper new extractants, that have the potential to be sustainably regenerated, are proposed for metal removal from aqueous phases. These extractants are a novel class of ionic liquids (ILs) with unsaturated fatty acids as anions (oleate and linoleate). The advantages of using these ILs are their simple synthesis, their sustainability (fatty...
Water-soluble ionic liquids can be prepared from halide ionic liquids by a new anion exchange method. This new method for the anion exchange in ionic liquids takes advantage of the strong basicity of phenolate anions (also called phenate anions or phenoxide anions). The principle behind the method is to first prepare the 4-tert-butylphenolate salt...
Questions
Question (1)
We are a start-up company working around industrial waste water treatment via electrocoagulation-flotation. It is our believe that the implementation of this technology is necessary to reach the sustainable development goals. Recently, we developed a lab reactor of our industrial installations that got the attention of universities. As to our believe still a lot of fundamental research and experience is necessary to industrially accept this technology, we decided to commercialise our lab reactor. See our website www.noahlabreactor.com
Combined with our lab reactor we would like to start an academic online community around electrocoagulation or does such a community already exist?
Thank you for providing feedback to my question.
Yours sincerely,
Dr. Dries Parmentier
