Wastewater from wastewater treatment plants (WWTPs) often requires further treatment before it can be safely reused. Lime is a common and affordable material used for this purpose, but its production can generate significant environmental impacts. This study developed an eco-friendly and effective lime substitute from eggshell waste for wastewater treatment. First, pre-treated wastewater effluent from WWTP El Jadida, Morocco, was collected and characterized. It was found that COD, BOD 5 , and TSS values showed non-conformity from Moroccan discharge standards, as well as high concentrations of heavy metals such as cadmium (Cd), zinc (Zn), aluminum (Al), chromium (Cr), manganese (Mn), lead (Pb), silver (Ag), beryllium (Be), copper (Cu) and cobalt (Co). These pollutants represent a potential risk to human health and the environmental ecosystem. To reduce this pollution, the optimal mass of lime powder obtained by thermal treatment of eggshell waste was determined by testing a concentration series of 6, 12, 18, 24, 30, and 36 g•L -1 . The findings confirmed that the addition of the optimal dose of prepared lime (24 g•L -1 ) resulted in a significant reduction in pollution parameters, with abatement rates of 77% for BOD 5 , 63% for COD and 66% for TSS, respectively. Furthermore, the eco-friendly lime substitute also showed promise in reducing the colorization rate for dyes by 84% and removing heavy metals through precipitation. However, the generated by-product loaded with toxic pollutants should be encapsulated in eco-materials to ensure safe operation and contribute to a sustainable management strategy for wastewater treatment.

“…Many techniques have been developed that can be used for removing dry matter from wastewater, such as adsorption [3], photocatalytic degradation [4,5], sonocatalytic degradation [6,7], electrochemical methods [8], electrocoagulation [9], reverse osmosis [10], ultrafiltration mixed matrix membranes [11] and electro-Fenton processes [12]. Out of all of these appro- aches, the adsorption is the one that is utilized rather frequently.…”

In this study, the optimum conditions for using activated carbon from Lepironia articulata (Retz.) Domin waste as an adsorbent were determined to remove dye pollutants from wastewater. The characteristics of the obtained activated carbon were assessed by performing energy dispersive X-ray (EDX), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopic (FTIR) techniques. The best optimum conditions for removing dye pollutants from wastewater were obtained at 30 mg/L methylene blue dye, 0.02 g of adsorbent and a contact time of 90 min. The maximum adsorption capacity of the activated carbon was 69.44 mg/g and the percentage removal achieved was more than 90%. The methylene blue dye adsorption data of the adsorbent were fitted to the Langmuir isotherm model. The prepared adsorbent was also applied for the removal of different colour dyes from real wastewater samples and found that the percentage removal was 71.3%, 62.7%, 66.3%, 68.4% and 72.0% for dark blue dye, red dye, pink dye, sky blue dye and yellow dye, respectively. These results indicated that the obtained activated carbon is highly effective and suitable adsorbent for removing different types of colour dyes and toxic organic substances from the wastewater.

“…The resulting MMM exhibited better operational performance in handling total suspended solids, chemical oxygen demands, total dissolved solids, and turbidity during textile wastewater filtration. 19 De et al directly impregnated zinc oxide (ZnO) nanoparticles (NPs) into polysulfone (PSF) to prepare a hollow fiber MMM. The resulting PSF MMM had the advantages of ZnO NPs, including better adsorption capacity, comparable porosity, and strong polar nature, which benefited the subsequent removal of copper(II) from aqueous solutions.…”

Modern industries usually require membrane separation technologies to perform well in organic solvent systems; however, typical commercialized reverse osmosis (RO) membranes often suffer from swelling and instability. Herein, we proposed a “CCC” post-treatment method to directly upgrade a traditional RO membrane and extend its potential application in the deep purification of integrated circuit materials. This method combines inorganic maifanite particles and organic polymer adamantane structures, benefiting from the merits of inorganic and organic materials, to successfully establish a stable mixed matrix membrane (MMM) structure on a thin-film nanocomposite (TFN) membrane surface after the CCC post-treatment, involving conditioning, cross-linking, and curing. The as-prepared TFN membrane was characterized using Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, energy-dispersive spectroscopy, scanning electron microscopy, and atomic force microscopy and evaluated using organic solvent RO. This study offers a new perspective and an effective solution for the separation of inorganic salts from organic solvents. The as-prepared TFN MMM was able to separate 99.1% of Li+, 96.8% of Ca2+, 96.9% of Zn2+, and 98.9% of Al3+ from an organic solvent through simple dead-end filtration with a stable performance and had a competitive capacity in the purification of lithium carbonate.
