Topic Information

Dear Colleagues,

With the global population on the rise and industrial activities expanding, the issue of wastewater pollution has escalated, posing threats to both the environment and human health. Pollutants such as heavy metals, antibiotics, microplastics, and others not only contaminate water sources but also present risks to human health through the food chain. It is imperative that we take urgent action to effectively treat wastewater and mitigate the harm it poses to both the environment and public health. In response to these challenges, our focus is on effective approaches for removing pollutants from wastewater.

This Topic serves as a vital platform for sharing recent advancements in the removal of toxic substances such as heavy metals, radionuclides, microplastics, PFAS, and antibiotics. We aim to explore methods such as membrane separation, adsorption, and advanced oxidation technologies, offering both a venue for comprehensive reviews and a space for original research contributions. Insights into the economic aspects of green or clean technology for water treatment are also highly encouraged.

A membrane system was applied for ultrapure water production from the treatment of saline effluent from the canned food industry. The industrial effluent presented a high saline concentration, including sodium chloride, calcium carbonate, calcium sulfates, and magnesium. The effluent was treated using a system of reverse osmosis (RO) and a post-treatment process consisting of ion exchange resins (IEXRs). The RO was accompanied by the addition of a hexametaphosphate dose (2, 6, and 10 mg/L) as an antiscalant to avoid the RO membrane scaling by minerals. In turn, IEXRs were used for water deionization to produce ultrapure water with a reduced concentration of monovalent ions. The antiscalant dose was 6 mg/L, producing clean water from RO permeates with an efficiency of 65–70%. The brine from RO was projected for its reuse in food industry processes. The clean water quality from RO showed 20% total dissolved solids (TDS) removal (equivalent to salts). The antiscalant inhibited the formation of calcium salt incrustation > 200 mg/L, showing low fouling. In turn, anionic resins removed 99.8% of chloride ions, whereas the monovalent salts were removed by a mix of cationic–anionic resin, producing ultrapure water with electrical conductivity < 3.3 µS/cm. The cost of ultrapure water production was 2.62 USD/m3. Full article

Industrial CO2 emissions contribute to pollution and greenhouse effects, highlighting the importance of carbon capture. Potassium carbonate (K2CO3) is an effective CO2 absorbent, yet its liquid-phase absorption faces issues like diffusion resistance and corrosion risks. In this work, the solid adsorbents were developed with K2CO3 immobilized on the selected porous supports. Al2O3 had an optimum CO2 adsorption capacity of 0.82 mmol g−1. After further optimization of its pore structure, the self-prepared support Al2O3-2, which has an average pore diameter of 11.89 nm and a pore volume of 0.59 cm3 g−1, achieved a maximum CO2 adsorption capacity of 1.12 mmol g−1 following K2CO3 impregnation. Additionally, the relationship between support structure and CO2 adsorption efficiency was also analyzed. The connectivity of the pores and the large pore diameter of the support may play a key role in enhancing CO2 adsorption performance. During 10 cycles of testing, the K2CO3-based adsorbents demonstrated consistent high CO2 adsorption capacity with negligible degradation. Full article
