Treatment of electroplating wastewater using electrocoagulation and integrated membrane

Water Science & Technology, Journal Year: 2024, Volume and Issue: 89(9), P. 2538 - 2557

Published: April 26, 2024

ABSTRACT Electroplating wastewater contains heavy metal ions and organic matter. These contaminants not only endanger the environment but also pose risks to human health. Despite development of various treatment processes such as chemical precipitation MBR, electrocoagulation (EC) ceramic membrane (CM), coagulation ultrafiltration (UF) reverse osmosis (RO), CM RO. methods are effective for low concentrations metals struggle with high concentrations. To address challenge treating electroplating content, this study focuses on from Dongfang Aviation Machinery Processing Plant. It introduces an EC integrated (IM) process wastewater. The IM comprises microfiltration (MF) membrane, nanofiltration (NF) RO membrane. Results indicated that under specific conditions, a pH 8, current density 5 A/dm2, electrode plate spacing 2 cm, 35 min electrolysis time, influent 10 IM, removal rates Zn2+, Cu2+, Ni2+, TCr in exceeded 99%. oxygen demand (COD), suspended solids (SS), total phosphorus (TP), nitrogen (TN), petroleum exceed 97%. Following continuous cleaning process, flux can consistently recover over 94.3%.

Recent advances in the fixed-electrode capacitive deionization (CDI): Innovations in electrode materials and applications

Environmental Functional Materials, Journal Year: 2023, Volume and Issue: 2(3), P. 290 - 303

Published: Dec. 1, 2023

Conventional capacitive deionization (CDI), originally developed as a promising desalination technique based on the formation of electric double layers (EDLs) at surface porous electrodes, has recently shown significant advancements. Notably, utilization pseudocapacitive electrodes demonstrated capability to enhance salt adsorption capacity (SAC) and selectivity specific ions. This comprehensive review encapsulates latest research endeavored in CDI, with an emphasis electrode materials their role augmenting SAC. The development broadened scope CDI applications water wastewater treatment resource recovery. Hence, we also evaluated manifold including recovery (e.g., lithium, phosphate nitrate), anion removal fluoride, sulfate, chromium arsenic), softening, heavy metals nickel, cesium, lead, copper, cadmium chromium) addition desalination. Lastly, provide forward-looking perspective forthcoming directions potential developments within realm technology.

Development of a Concept for Closing the Water Cycle in the Surface Treatment of Ferrous and Non-Ferrous Metals

Sustainability, Journal Year: 2025, Volume and Issue: 17(5), P. 2212 - 2212

Published: March 4, 2025

This study examines the treatment of industrial wastewater generated during vibro-abrasive steel and Zn-Al alloy parts machining in a Polish metal-processing plant. The process uses grinding fluids, which are sent for disposal after becoming saturated with contaminants, incurring high costs. A two-stage filtration was investigated: an initial bag (pore size 5 µm) followed by low-pressure (4 bar) ultrafiltration polyacrylonitrile membranes (30 kDa cut-off). studies were carried out on laboratory scale cross-flow system using batch configuration. filtrate flux 0.116 mL min−1 cm−2 0.050 wastewater, respectively. Key physicochemical parameters, including turbidity, COD, TOC, analysed raw feed, retentate, permeate. Significant reductions contaminant concentrations achieved, comparable total efficiencies both wastewaters tested. anionic surfactants, phosphorus non-ionic surfactants ranged from 80% to almost 100%. complete removal suspended solids achieved. novelty this research lies applying flat-sheet treat vibratory ferrous non-ferrous materials recycle reclaimed water, has not been systematically explored previous studies. demonstrates potential membrane recycling, offering insights into environmentally friendly energy-efficient management wastewater.

Preparation of Thin-Film Composite Membranes for Magnesium–Lithium Separation by Interface Polymerization of Linear Diamines and Piperazine as Aqueous Monomers

ACS Applied Engineering Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 8, 2025

This study investigates the effectiveness of thin-film composite (TFC) membranes prepared through interfacial polymerization (IP) using various linear diamines (LD) in conjunction with piperazine (PIP) to mitigate magnesium ion permeation. Among tested LDs, 1,4-butylenediamine (BDA) was selected for further analysis due its superior performance TFC membrane fabrication. A systematic examination conducted on effects varying BDA PIP ratios and their concentrations separation efficiency membranes. Characterization techniques, including attenuated total reflectance Fourier-transform infrared (ATR-FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy-dispersive (EDS), atomic force (AFM), were employed elucidate structural characteristics surface morphology The results show that longer LD carbon chains aqueous phase lead higher molecular weight cutoff (MWCO) a looser structure Furthermore, increasing concentration slightly raises MWCO but significantly enhances salt rejection stronger charge effects. By simulating brine composition diluted 10 times from Yiliping Salt Lake Qinghai Province, China. typical feed high-magnesium (CMg2+ = 7500 mg/L) high-magnesium-to-lithium ratio (Mg2+/Li+ 28.42), an optimal additive achieved remarkable SLi,Mg 31.66 along Mg2+ rate 96.34%, coupled favorable water permeability properties. These findings underscore significant application potential this technology. Finally, we discuss mechanisms by which interact during IP process influence both properties
