“…BESs operate with zero or minimal external energy consumption, generate very little sludge and require minimal reactor maintenance [15][16][17][18]. Multiple metals including V(V), Cr(VI), As(III), Tl (I), Cd(II), Mn(II), Co(II), Ni(II) and Cu(II) [11][12]16,[19][20][21][22][23][24][25][26][27] and Cu(II), Co(II) and Li(I) [28][29][30][31][32]. The concept of using optimized MFC and MEC stacked BESs for the efficient deposition and separation of W(VI) and Mo(VI) from mixed aqueous solutions with simultaneous hydrogen production has been demonstrated in our recent study [10] using an initial pH of 2.0, a W(VI)/Mo(VI) molar ratio of 1 : 1 and a stainless steel sheet cathode electrode.…”

The deposition and separation of W and Mo from aqueous solutions with simultaneous hydrogen production was investigated in stacked bioelectrochemical systems (BESs) composed of microbial electrolysis cell (1#) serially connected with parallel connected microbial fuel cell (2#). The impact of W/Mo molar ratio (in the range 0.01 mM : 1 mM and vice-versa), initial pH (1.5 to 4.0) and cathode material (stainless steel mesh (SSM), carbon rod (CR) and titanium sheet (TS)) on the BES performance was systematically investigated. The concentration of Mo(VI) was more influential than W(VI) in determining the rate of deposition of both metals and the rate of hydrogen production. Complete metal recovery was achieved at equimolar W/Mo ratio of 0.05 mM : 0.05 mM. The rates of metal deposition and hydrogen production increased at acidic pH, with the fastest rates at pH 1.5. The morphology of the metal deposits and the valence of the Mo were correlated with W/Mo ratio and pH. CR cathodes (2#) coupled with SSM cathodes (1#) achieved a significant rate of hydrogen production (0.82 ± 0.04 m/m/d) with W and Mo deposition (0.049 ± 0.003 mmol/L/h and 0.140 ± 0.004 mmol/L/h (1#); 0.025 ± 0.001 mmol/L/h and 0.090 ± 0.006 mmol/L/h (2#)).

“…At present, several methods have been developed to reduce pollution from liquid waste in the form of physicochemical technology including ion exchange, coagulation, flocculation, chemical oxidation, electrochemical techniques, membrane separation, adsorption, and photocatalysis which have been applied for the purpose of removing dyes and metal ions from waste water [3][4][5][6][7][8][9][10][11]. From some of these technologies, the adsorption method is more often used for the treatment of liquid waste containing heavy metals or hazardous dyes.…”

Biomass of algae is a very potent adsorbent for absorbing liquid waste containing heavy metals and organic dyes. This study purposes to confirm the ability of adsorbents from green algae Nannochloropsis sp. modified with silica (ASN) and followed by coating magnetite particles (ASN-MPs) to absorb simultaneously the mixture of methylene blue (ME) and Cu(II) cations in aqueous solution. Simultaneous sorption of ME and Cu(II) cations to ASN and ASN-MPs was carried out by the Batch method with the interaction pH condition 7, contact time (15–120 minutes), and initial concentrations of ME and Cu(II) cations (0.1–1.0 mmol·L− 1). The simultaneous sorption parameters of ME and Cu(II) cations by ASN-MPs trend to comply the pseudo-second-order kinetics model by rate constant values for pseudo-second-order (k2), respectively 8.98 × 10− 3 and 9.78 × 10− 3 (g·mmol− 1·min− 1). The ME adsorption pattern and Cu(II) cations in the competition on ASN-MPs adsorbents, each tends to follow the Freundlich and Langmuir adsorption isotherms. Based on adsorption data, Cu(II) cations have a greater adsorption rate and capacity (qexp) compared to ME at the same contact time and initial concentration. Modified adsorbent from algae Nannochloropsis sp. with silica matrix and magnetite particle coating, is an adsorbent that has a high effectiveness in the collective sorption of ME and Cu(II) cations. Therefore, these adsorbents can be used for the adsorption of cation mixtures of heavy metals and organic dyes that are cationic in solution.

“…Effective copper removal from wastewater has always been of great interest to researchers around the world. Cementation [14][15][16][17], adsorption [5,9,10,18,19], membrane filtration [20][21][22], electrodialysis [20,23], and photocatalysis [19,24] are the most common methods and techniques for the extraction of copper from wastewater. Each method and/or technology has its own advantages and disadvantages [25][26][27][28][29].…”

The circular economy for sustainable economic deployment is strongly based on the re-use of secondary products and waste utilization. In the present study, a new effective cementation method for recovering valuable metallic copper from industrial wastewater using Fe0 powders is reported. A high-speed mixer-disperser (HSMD) capable of providing a cavitation effect was used for the rapid intake, dispersion, and mixing of Fe0 powder in an acidic wastewater solution (pH ≈ 2.9) containing copper ions mainly in the form of CuSO4. Three iron powders/particles were tested as the cementation agent: particles collected from industrial dust filters (CMS), water-atomized iron-based powder AHC100.29, and sponge-iron powder NC100.24. The effects of mixing regimes and related mixing conditions on the effectiveness of the Cu cementation process were evaluated by comparison between the HSMD and a laboratory paddle mixer. It was observed that the use of cavitation provided more efficient copper removal during the copper cementation process in comparison to the standard experiments with the propeller mixer. Under the cavitation regime, about 90% of copper was cemented in the first five minutes and the final copper removal of 95% was achieved using all three Fe0 powders after seven minutes of cementation. In comparison, only around 55% of copper was cemented in the first seven minutes of cementation using the traditional mixing method.
