Acute Toxicity Assessment of Textile Wastewater Treated with Pinus patula Biochar Using Daphnia pulex

Water, Journal Year: 2025, Volume and Issue: 17(8), P. 1143 - 1143

Published: April 11, 2025

The discharge of textile wastewater (TWW) into the environment releases multiple toxic substances that pose a significant threat to aquatic life. Most studies evaluating treatment efficiency focus on removal parameters, such as chemical oxygen demand (COD), total organic carbon (TOC), dissolved (DOC), biochemical (BOD), and colour. One processes has presented high efficiencies in TWW is use biochar (BC) an adsorbing material. BC shown ability remove complex from water since it able decrease content COD, TOC, DOC. However, toxicity treated effluents not been widely studied. In this regard, essential only treatments removing matter but also their reduce WW toxicity. This research evaluates acute real with Pinus patula by using Daphnia pulex sentinel species. For purpose, D. individuals were exposed BC-treated for 48 h, mortality defined absence movement limbs antennas. It was found although P. 120 min eliminated 72.8% initial DOC under optimal conditions (pH 3 13.5 g/L dose), effluent remained toxic, inducing 85.7% 71.4% rates 100% (v/v) 50% dilutions. Despite increase survival rate due protective effect achieved constituents contained reconstituted samples, these findings emphasize necessity conducting before considering after having treated.

A Study of the Feasibility of Pinus patula Biochar: The Regeneration of the Indigo Carmine-Loaded Biochar and Its Efficiency for Real Textile Wastewater Treatment

Processes, Journal Year: 2024, Volume and Issue: 12(5), P. 939 - 939

Published: May 5, 2024

The feasibility of an adsorbent material like biochar (BC) depends on its regeneration capacity and ability to achieve high removal efficiencies real wastewater (WW) effluents. In this study, the Pinus patula BC previously used in Indigo Carmine from water was evaluated. technique that resulted highest desorption efficiency a thermo-chemical method consisted heating spent stove at 160 °C for 45 min followed by with ethanol (C2H6O) concentration 75% 6 h. Through method, it found could be seven consecutive adsorption–desorption cycles. also assessed evaluating adsorbent’s textile WW. Under optimal operational conditions (solution pH = 3, dose 13.5 g/L, particle size 300–450 µm), terms colour dissolved organic carbon (DOC) were 81.3 76.8%, respectively, 120 treatment. results obtained studies treatment WW suggested use suitable scaled industrial level, contributing sustainable development circular bioeconomy using waste solve dye pollution problem another waste.

Malachite Green Dye Removal in Water by Using Biochar Produced from Pinus patula Pellet Gasification in a Reverse Downdraft Reactor

Sustainability, Journal Year: 2024, Volume and Issue: 16(24), P. 11043 - 11043

Published: Dec. 17, 2024

The efficiency of the elimination malachite green dye (MG) in water was investigated using biochar (BC) obtained from Pinus patula wood pellets (BC-WP). biomass gasified, reaching a temperature 391.07 °C near reactor wall. During adsorption tests, three independent factors were considered: solution pH, BC concentration, and particle size, which optimized different study ranges (4–10, 6–12 g/L, 150–600 μm, respectively) at 30 min contact time. response surface methodology used through face-centered central composite design for this purpose. experimental results analyzed to develop quadratic regression model that fitted data achieved. highest removal percentage MG by BC-WP (94.25%) attained under pH 10, concentration 12 an average size 225 μm. Furthermore, validated found explain 94.72% results, demonstrating ability remove target dye. Thus, new sustainable alternative conventional systems treating dye-polluted is proposed, utilizing solid by-product thermochemical process, contributing circular economy.
