Latar belakang: BOD, minyak dan lemak dalam air limbah domestik berbahaya bagi lingkungan. Polutan tersebut dapat dihilangkan dengan teknik adsorpsi menggunakan karbon aktif kulit pisang dengan efisiensi mencapai 70%. Tujuan penelitian yaitu mengkaji pengaruh dosis karbon aktif dan waktu kontak terhadap penyisihan BOD, minyak dan lemak, serta kinetika adsorpsinya, morfologi permukaan dan unsur kimia karbon aktif kulit pisang.Metode: Penelitian ini menggunakan Rancangan Acak Lengkap Faktorial. Faktor pertama dosis karbon (1,5 g, 3 g, 4,5 g) dan faktor kedua waktu kontak (30, 60, dan 90 menit), dengan 2 ulangan. Percobaan adsorpsi menggunakan sistem batch dengan gelas beker. Parameter penelitian meliputi BOD yang dianalisis dengan titrasi iodometri (SNI-6989.72:2009), serta minyak dan lemak dengan metode gravimetri (SNI-6989.10:2011). Analisis data menggunakan analisis deskriptif yang meliputi efisiensi penyisihan, kinetika adsorpsi, morfologi permukaan dan elemen karbon aktif. Hasil: : Dosis karbon aktif dan waktu kontak mampu menyisihkan BOD, minyak dan lemak hingga 24% dan 97%. Kinetika adsorpsi pseudo-second-order dengan R2 0,98 dan 0,99 menggambarkan adsorpsi BOD, minyak dan lemak. Karbon aktif sebelum adsorpsi pori-porinya terbuka dan permukaannya bersih, sedangkan setelah adsorpsi pori-porinya tertutup, permukaan padat, dan bergelombang. Elemen karbon sebelum adsorpsi terdiri dari C, O, K sebesar 76,53%, 19,46%, 2,24%, dan setelah adsorpsi terdiri dari C 78,94% dan O 19,87%.Simpulan: Dosis karbon dan waktu kontak berpengaruh terhadap penyisihan BOD, minyak dan lemak. Kinetika adsorpsi pseudo-second-order menggambarkan adsorpsi BOD, minyak dan lemak. Morfologi permukaan dan unsur karbon aktif sebelum dan sesudah adsorpsi berbeda. Title: Removal of BOD, Oil and Grease in Domestic Wastewater Using Activated Carbon from Banana PeelsBackground: BOD, oil and grease in domestic wastewater are harmful to the environment. These pollutants can be removed with adsorption techniques by activated carbons using banana peels with an efficiency up to 70%. The aim of the study was to analyze the impact of activated carbon doses and the contact time on BOD, oil and grease removal, as well as the kinetics of adsorption, surface morphology and chemical elements from banana peel activated carbon.Method: This experiment used a factorial completely randomized design. The first factor was carbon dosage (1.5 g, 3 g, 4.5 g) and the second was contact time (30, 60, and 90 minutes), with 2 replications. The adsorption experiment used a batch system with a glass beaker. The research parameters included BOD analyzed by iodometric titration (SNI-6989.72:2009), and oil and grease by gravimetric method (SNI-6989.10:2011). Data analysis using descriptive analysis which includes removal efficiency, adsorption kinetics, surface morphology and activated carbon elements.Result: The activated carbon dosage and contact time removed BOD, oil and grease up to 24% and 97%, respectively. Pseudo-second-order adsorption kinetics with R2 0.98 and 0.99 described the adsorption of BOD, oil and grease. Activated carbon before adsorption had open pores and a clean surface, while after adsorption the pores were closed, and the surface was solid and ridged. The carbon element before adsorption consists of C, O, and K at 76.53%, 19.46%, and 2.24%, and after adsorption consists of C at 78.94% and O at 19.87%.Conclusion: Carbon dosage and contact time affected the removal of BOD, oil and grease. The pseudo-second-order adsorption kinetics described the adsorption of BOD, oil and grease. The surface morphologies and elements from activated carbon before and after adsorption as different.

The Dual Performance of Moringa Oleifera Seeds as Eco-Friendly Natural Coagulant and as an Antimicrobial for Wastewater Treatment: A Review

et al. 2023

In this review, collected information related to Moringa Oleifera seeds was evaluated, such as their properties and the main active components involved in their processes, as well as their dual efficiency as both antimicrobials and natural coagulants for treating contaminated effluents. Furthermore, discussions were completed about perspectives on progress related to this field of research to understand the bioactive properties of these seed compounds, including their antibacterial, antifungal, and antiviral activity. In addition to the coagulant properties that have been quantitatively assessed, studies have examined the underlying coagulating mechanism, and seed processing techniques. In addition, the challenges associated with the use of conventional coagulants (metals or polymers) have led to numerous research efforts towards the development of natural plant-based coagulants that are eco-friendly to treat wastewater and offer a large variety of other advantages, such as their wide availability, the reduction of by-product generation, the reduction of costs, and greater biodegradability. Based on the results of different researchers, and regarding the appraisals using Moringa Oleifera seeds for wastewater treatment processes, many studies encourage their use for those operations. Due to their extensive and potent properties as an antibacterial and a coagulant, Moringa Oleifera seeds are still used today as a promising wastewater treatment method. Finally, this paper provides suggestions and comments, as well as identifies the knowledge gaps, and makes recommendations for future research development strategies, such as studying the contents of Moringa Oleifera seeds, their interactions with colloids present in wastewater, understanding their stability and behavior, assessing the performance of seed-derived flocculants according to pH values, isolating and characterizing the active compounds to determine the toxicity and optimum dose to be used as effective antimicrobials, and removing heavy metals.
