Optimization of Pyrolysis Parameters by Design of Experiment for the Production of Biochar from Sewage Sludge

Environments, Journal Year: 2024, Volume and Issue: 11(10), P. 210 - 210

Published: Sept. 24, 2024

Sewage sludge management is a key concern in today’s world. Improper disposal can lead to various environmental issues including air, water and soil pollution. Among the available technologies, thermal treatments, particularly pyrolysis, are gaining interest for their ability reduce sewage volume recover materials energy from it. This study explored influence of some relevant parameters pyrolysis process. The design experiment, named central composite design, was accounted optimize temperature, heating rate residence time order maximize biochar yield its CO2 adsorption capacity. A two-factor interaction model provided satisfactory interpretation results. Within studied ranges, maximum values 47.8 wt% 0.514 mol CO2/kg were obtained capacity, respectively. Two significant experiments repeated different system highlighting how other factors (e.g., reactor geometry, granulometry, etc.) quantity quality produced biochar. under best conditions characterized by surface area 124 m2/g an ash content 61 wt%. Lastly, theoretical balance showed that drying process main energy-intensive step sludge.

Plant-Based Flocculants as Sustainable Conditioners for Enhanced Sewage Sludge Dewatering

Water, Journal Year: 2024, Volume and Issue: 16(20), P. 2949 - 2949

Published: Oct. 16, 2024

With the aim to establish clean and sustainable sludge treatment, green conditioning using natural flocculants has recently gained a growing interest. In this study, variety of plant materials, namely Moringa (Moringa oleifera) seeds, Fenugreek (Trigonella foenum-graecum) Potato (Solanum tuberosum) peels, Aloe (Aloe vera) leaves, Cactus (Opuntia ficus indica) cladodes, Phragmites (Phragmites australis) stems, were evaluated for their potential bioflocculant activity in sewage sludge. They thoroughly characterized determine active flocculating compounds. Sludge dewaterability was by assessing various parameters, including specific resistance filtration (SRF), dryness cake (DC), total suspended solid removal (TSS) from filtrate. The collected results physicochemical characterizations materials suggest that main agents are carbohydrates proteins Moringa, Potato, Phragmites. Additionally, all tested plant-based demonstrated effective dewatering performance. Interestingly, compared chemical flocculant polyaluminum chloride, showed superior effects, yielding lowest SRF values highest DC. As result, use these improved filterability, leading significant solids properties can be attributed high protein sugar content, which facilitates separation bound water through charge neutralization bridging mechanisms. Thus, flocculants, particularly presents promising eco-friendly approach enhance safer disposal valorization.
