In the current work, rice husk (RH) biomass was pyrolyzed using tartaric acid as an activating agent to produce activated carbon (AC). For 60 min, procedure run at 700 °C and 5 L/min of nitrogen (N2) flow rate. The study used response surface methodology (RSM) a 3-level Box-Behnken design (BBD) optimize extraction efficiency (RHAC) in eliminating reactive orange 16 (RO16) dye from aqueous solution. Different process parameters, such pH (2–12), RHAC dose (0.04 – 0.14 g), time (60-240 min), were chosen part optimization method. When solution's 2, adsorbent dosage 0.09 g, contact 240 maximum amount removal (53%) achieved. This work demonstrates ability use abundant create carbon, which can be effectively remove organic dyes.

Advancements in application of modified biochar as a green and low-cost adsorbent for wastewater remediation from organic dyes

Royal Society Open Science, Год журнала: 2024, Номер 11(5)

Опубликована: Май 1, 2024

Synthetic organic dyes, which are resistant to biodegradation, pose a notable health risk, potentially leading cancer and respiratory infections. Researchers have addressed this concern by exploring physicochemical methods remove dyes from wastewater. A particularly promising solution involves modified biochar adsorbents, demonstrate high efficiency in dye removal. Biochar, charcoal-like material derived biomass pyrolysis, offers advantages such as low cost, eco-friendliness, reusability. Beyond its role sustainable soil remediation, proves effective removing wastewater after undergoing physical or chemical modification. Acid–base activation metal–heteroatom impregnation enhances biochar's adsorption capacity. This comprehensive review examines the attributes of biochar, common for production modification, impacts raw materials, pyrolysis temperature, heating rate residence time. It further elucidates mechanism removal assessing factors influencing efficiency, including feedstock, pH, particle size, initial concentration, dosage reaction explores challenges, opportunities, reusability regeneration treating also discusses recent advances using adsorption-based biochar. The ultimately advocates enhancing performance through post-modification.

Treatment of water from the textile industry contaminated with indigo dye: A hybrid approach combining bioremediation and nanofiltration for sustainable reuse

Case Studies in Chemical and Environmental Engineering, Год журнала: 2023, Номер 8, С. 100498 - 100498

Опубликована: Сен. 26, 2023

In recent decades, the extensive use of synthetic dyes in dye-based industries, particularly textile sector, has led to environmental contamination, raising concerns about water quality and human health. This study aimed develop a sustainable approach for treating wastewater contaminated with indigo dye through hybrid combining bioremediation nanofiltration reuse. first stage, two bioaugmentation strategies were compared: using native microorganisms (R-1) activated sludge from municipal treatment plant (R-2). Both effectively reduced chemical oxygen demand (COD) 200 mg/L eliminated over 90% color. Statistical analysis showed no significant difference COD removal efficiencies between R-1 R-2. Correlation revealed strong association (>99%) COD, suspended solids (SS) concentration, color reactors, providing insights into monitoring treatment, potential cost reductions benefits. second (NF) organic membranes was employed obtain high-quality permeate reuse denim washing. Permeability measurements demonstrated similar membrane behavior (NF 270 Alfa Laval NF) at various transmembrane pressures (TMPs). achieved rejection rates exceeding 96% efficiency 80% all TMPs. NF tests R-2 effluent higher flux 23.71 L·h−1·m−2 TMP 5 bar, exhibiting superior compared membrane. The techno-economic biological treatment/NF have mean unit 0.97 USD/m3, indicating economic feasibility competitiveness against commercial purification processes
