Abstract

Textile industry wastewater is a very complex pollutant-containing waste with high dye intensity, requiring proper and appropriate treatment. Membrane technology is one of the appropriate methods for treating textile wastewater due to several advantages such as environmentally friendly and biopolymer-based processing. Therefore, this review aimed to determine the effectiveness of membrane technology and provide information regarding the appropriate treatment of textile wastewater. The articles subjected to review were obtained from several journal sources such as ScienceDirect, Elsevier, Springer, Google Scholar, and national journals. The results showed that several membranes had been used in textile wastewater treatment, such as PTFE (Polytetrafluoroethylene), PES (Polyethersulfone), Polysulfone-Polyvinyl Pyrrolidone Blend Polymer Composite Membrane, CA (Cellulose Acetate), Cellulose Membrane of Sargassum Sp., polysulfone (PSF), Bacterial Cellulose Membrane, and cellulose acetate propionate (CAP). Furthermore, membrane technology was found to reduce dye pollutants in textile wastewater with the highest coefficient value of approximately 97%.

Abstract

The rapid rise in urbanization and waste production has significantly impacted the environment. Therefore, community-based waste management is a crucial approach for reducing the environmental impact of domestic and household waste. This community service project aims to promote environmental sustainability through community-based education on waste management. This initiative was carried out in Dech Charoen Village, Thailand, aiming to increase community awareness about the importance of sustainable waste management practices. This paper discusses the community service activities conducted in Dech Charoen Village and their impact on community empowerment and environmental sustainability. The activities included a sharing session on community-based waste management, outreach on the reduce, reuse, and recycle (3R) principle for inorganic waste, and practical outreach on processing organic waste using a composting machine. Results showed a considerable rise in awareness of waste management methods, with more than 90% of participants achieving a better understanding of waste segregation, recycling, composting practices, and the importance of community involvement.

Abstract

Pencemaran ion sulfat menjadi masalah serius dalam lingkungan, terutama akibat aktivitas industri seperti pertambangan dan pengolahan mineral. Tingginya konsentrasi sulfat dapat merusak kualitas air dan kesehatan manusia. Tujuan dari artikel ini adalah untuk mengevaluasi efektivitas material maju dalam menghilangkan ion sulfat dari air limbah. Metode yang digunakan mencakup studi literatur yang komprehensif, dengan fokus pada berbagai material seperti nanomaterial, komposit, dan resin penukar ion yang telah terbukti efektif dalam penghilangan sulfat. Hasil penelitian menunjukkan bahwa penggunaan ettringit dan polialuminum chloride (PAC) dapat mencapai efisiensi penghapusan sulfat hingga 90%. Selain itu, material seperti hidrokalumite dan resin penukar ion juga menunjukkan potensi yang signifikan. Kesimpulan dari penelitian ini menegaskan bahwa pemilihan material yang tepat dan pengaturan kondisi operasional, seperti pH dan waktu kontak, sangat berpengaruh terhadap efisiensi penghilangan sulfat. Oleh karena itu, penggunaan material maju menawarkan solusi yang lebih berkelanjutan untuk mengatasi pencemaran sulfat dalam industri, sekaligus mendukung pengelolaan air limbah yang lebih efektif dan ramah lingkungan. Artikel ini diharapkan dapat memberikan wawasan baru untuk praktik pengolahan air yang lebih baik di masa depan.

Abstract

Industrial wastewater generally contains heavy metalssuch as lead, cadmium, arsenic, nickel, chromium and mercury. Contamination of water with these elements is very dangerous and will pollute the environment, so a suitable waste water treatment is required. This review aims to find out the efficient methods of handling industrial wastewater and the benefits of biomass. Many scientific methods are used in this regard, including adsorption, chemical precipitation, ion exchange, electrochemical treatment, membrane filtration, coagulation and flocculation. However, some of these techniques have drawbacks such aswill produce a large amount of metal sludge, making it difficult to recycle metal, and the formation of toxic sludge or other wastes. Of all these techniques, adsorption with adsorbent biomasshas been widely known because it is an economical, effective and environmentally friendly processing technique, so this method is suitable for treating industrial wastewater. The use of biomass as an adsorbent is intendedto help reduce dependence on fossil raw materials and greenhouse gas emissions that contribute to climate change.

Abstract

Industrial and biological wastes are major contributors to environmental pollution and contain high levels of organic matter that can generate short-chain fatty acids (SCFA) through microbial fermentation. SCFAs are important not only as bioenergy precursors in industrial waste management but also as key biomarkers of gut microbiota activity in biological samples. This review provides a comparative analysis of analytical methods used to detect SCFAs in both industrial and biological matrices, focusing on High-Performance Liquid Chromatography (HPLC), Gas Chromatography with Flame Ionization Detection (GC-FID), and Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS). The findings reveal that HPLC—particularly Ion-Exclusion HPLC—is most effective for analyzing complex industrial waste samples such as waste-activated sludge (WAS) and palm oil mill effluent (POME), whereas GC-FID is more suitable for volatile-rich wastes like vinasse. Meanwhile, LC-MS/MS demonstrates exceptional accuracy and sensitivity for biological matrices such as feces, serum, and urine, allowing detection at ultra-trace concentrations. These insights underscore the need for optimized, waste-specific detection techniques to enhance environmental monitoring, waste valorization, and health-related SCFA research. Future studies should focus on developing rapid, cost-effective, and IoT-integrated detection systems to support real-time monitoring of both industrial and biological wastes.

Abstract

Vinasse is a major liquid waste generated from the bioethanol industry and contains a high concentration of sulfate ions that may cause environmental problems if not properly managed. This study investigates sulfate adsorption from vinasse wastewater using a one-pot synthesized quaternary ammonium polymer, with a focus on functional group interactions analyzed by Fourier Transform Infrared Spectroscopy (FTIR). Quantitative adsorption experiments were conducted to confirm sulfate removal, while FTIR analysis was employed to examine changes in functional group characteristics before and after adsorption under various operating conditions. The quantitative results demonstrate that sulfate adsorption proceeds rapidly, achieving a removal efficiency of approximately 87.5534% with an adsorption capacity of 10.6800mg/g at a contact time of 20 minutes under the investigated conditions. FTIR spectra indicate that sulfate adsorption does not alter the main polymer structure and is primarily associated with changes in the intensity of bands related to quaternary ammonium groups and sulfate vibrations, suggesting non-covalent interactions dominated by electrostatic attraction, with possible contributions from hydrogen bonding. Overall, this study provides quantitative evidence of sulfate adsorption from real vinasse wastewater and demonstrates the usefulness of FTIR analysis in elucidating interaction behavior between sulfate ions and quaternary ammonium polymer functional groups.
