“…The coagulation-flocculation process is the conventional means of removing color and turbidity, and has been shown to outperform other wastewater treatment processes, despite using a simple and economic operation to achieve a high removal efficiency. The process involves the separation of solids and liquids using metal salts (coagulants) to destabilize the dissolved particles and polymeric materials (flocculants) to aggregate particles (Ashrafi et al 2015;Ciputra et al 2010;Hameed et al 2018;Lee et al 2014;Teh et al 2016). Given the demonstrated ability of coagulation-flocculation to remove color and turbidity from water, it is reasonable to expect that this process can be potentially used for lignin removal.…”

This study assesses the application of iron (III) trimesic (Fe-BTC) as a coagulant-flocculant to remove lignin from pulp and paper (P&P) wastewater. In this research, Fe-BTC was characterized by X-ray diffraction (XRD), while the functional groups of Fe-BTC and lignin were analyzed by Fourier transform infrared (FT-IR) spectroscopy. Scanning electron microscopy (SEM) determined the surface morphology of the material. The influential parameters affecting lignin removal included the initial lignin concentration, the quantity of Fe-BTC, and the pH which were investigated using a single batch mixing system. The experimental and optimum operational conditions were determined using Box-Behnken design (BBD). Fe-BTC dosage plays a major role in efficiently removing lignin, while the pH and initial lignin concentration had no significant effect. Greater than 80% removal efficiency could be achieved with a Fe-BTC dosage as low as 2 g/L. The proposed mechanism of lignin aggregation was that Fe molecules were released from unsaturated sites of Fe-BTC and then formed new bonds with O in the methoxy lignin group. The interaction between Fe-BTC and lignin was π-π stacking (benzene ring), which explains the formation of F-O bonds in the lignin sludge. ABSTRAK Kajian ini menilai penggunaan besi (III) trimesik (Fe-BTC) sebagai bahan penggumpal untuk menyingkirkan lignin daripada air sisa pulpa dan kertas (P&P). Dalam kajian ini, Fe-BTC dicirikan oleh pembelauan sinar-x (XRD) manakala kumpulan fungsian Fe-BTC dan lignin dianalisis melalui spektroskopi transformasi Fourier inframerah (FT-IR). MikroskopElektron Imbasan (SEM) menentukan morfologi permukaan untuk bahan. Parameter penting yang menyebabkan penyingkiran lignin adalah termasuk kepekatan pemula lignin, kuantiti Fe-BTC dan pH yang dikaji menggunakan sistem campuran kelompok tunggal. Syarat uji kaji dan pengoperasian optimum telah ditentukan dengan menggunakan reka bentuk Box-Behnken (BBD). Dos Fe-BTC memainkan peranan penting dalam menyingkirkan lignin dengan cekap, manakala pH dan kepekatan pemula lignin tidak menunjukkan kesan yang ketara. Lebih daripada 80% kecekapan penyingkiran boleh dicapai dengan dos Fe-BTC serendah 2 g/L. Mekanisme cadangan daripada pengagregatan lignin adalah bahawa Fe molekul dibebaskan dari unsatured tapak Fe-BTC dan kemudian membentuk ikatan baharu dengan O dalam kumpulan lignin metoksi. Interaksi antara Fe-BTC dan lignin ialah susunan π-π (gelang benzena) yang menjelaskan pembentukan ikatan F-O dalam enap-cemar lignin.Kata kunci: Fe-BTC; lignin; MOFs; pulpa dan kertas; rangka kerja logam-organik; reka bentuk Box-Behnken

“…[59,60] Tanfloc has been largely used as a natural coagulant and flocculant for treatment of domestic wastewater to enhance the performance of clarification in biological treatment units. [61][62][63] Improvement in the nitrification process was observed by increasing the percentage of ammonia-oxidizing bacteria and nitrite-oxidizing bacteria as a consequence of the favorable environment due to the application of tanfloc. [63] In recent work proposing the use of tanfloc as a biomaterial, tanfloc-based polyelectrolyte multilayers were shown to promote stem cell adhesion and proliferation, to improve hemocompatibility through interactions with platelets and serum proteins, and to possess antibacterial activity as well.…”

Electrospinning has emerged as a versatile and accessible technology for fabricating polymer fibers, particularly for biological applications. Natural polymers or biopolymers (including synthetically derivatized natural polymers) represent a promising alternative to synthetic polymers, as materials for electrospinning. Many biopolymers are obtained from abundant renewable sources, are biodegradable, and possess inherent biological functions. This review surveys recent literature reporting new fibers produced from emerging biopolymers, highlighting recent developments in the use of sulfated polymers (including carrageenans and glycosaminoglycans), tannin derivatives (condensed and hydrolyzed tannins, tannic acid), modified collagen, and extracellular matrix extracts. The proposed advantages of these biopolymer-based fibers, focusing on their biomedical applications, are also discussed to highlight the use of new and emerging biopolymers (or new modifications to well-established ones) to enhance or achieve new properties for electrospun fiber materials.

“…Therefore, so many studies have been done in order to effectively treat POME such as coagulation-flocculation (Hameed et al, 2018), Electrocoagulation (Nasrullah et al, 2020 andBashir et al, 2017), Electro-oxidation (Bashir et al, 2017), Adsorption and photo catalytic oxidation (Ng, 2021). Natural coagulants have recently received much attention for POME treatment application.…”

“…It is found naturally in plants, especially pulses that have the ability to bind to and precipitate proteins and other macromolecules. Commercially speaking, it is known as modified condensed tannin which is an organic coagulant extracted from Acacia tree (Hameed et al, 2018). Accordingly, the performance of simultaneous oxidation and natural coagulant for POME treatment was not documented.…”

<p>The current research was aimed to investigate the performance of combined persulfate oxidation process and tannin via coagulation-flocculation processes as a post treatment of anaerobically treated palm oil mill effluent (AnT-POME). Different dosages of sodium persulfate (Na2S2O8, 238 g/mol) 0.1 (w/v) and modified tannin were combined as a simultaneous reaction to treat AnT-POME. Different dosages of tannin ranged between 0.02g and 0.12g with pH variation ranged between 3 and 11 retention and retention time of (30, 90, 120 and 180) were evaluated. The performance of the treatment processes was evaluated based on the removal of three different parameters namely; chemical oxygen demand (COD), ammoniacal nitrogen (NH3-N) and color under the following operational conditions: persulfate dosage, tannin dosage, pH and retention time (min). Using persulfate alone, the maximum removal efficiency of COD, color, and NH3-N were 50%, 60% and 22%, respectively by using 4 mL of 0.1 (w/v) persulfate dosage at pH 7 and 60 min retention time. While, the performance of simultaneous reaction improve the removal efficiencies of COD, color, and NH3-N to 90%, 96% and 44%, respectively using 4 mL of 0.1 (w/v) persulfate and 0.06 g of tannin during 120 min retention time at pH 7. However, the maximum removal of NH3-N (59%) was achieved at pH 11. The study revealed that the simultaneous persulfate/tannin reaction is a promising treatment method for industrial wastewater treatment.</p>
