Reviewing Improved Anaerobic Digestion by Combined Pre-Treatment of Waste-Activated Sludge (WAS)

Sustainability, Journal Year: 2024, Volume and Issue: 16(15), P. 6419 - 6419

Published: July 26, 2024

The anaerobic digestion of wastewater treatment sludge (WAS) produces a “green” biogas while reducing the amount residual sludge. To increase yield biogas, several individual or combined pre-treatment methods WAS can be used. These substantially reduce volatile suspended solids (VSSs) and their associated total chemical oxygen demand (TCOD). Pre-treating will methane by 15 to 30%. Although have been dealt with in research large-scale operations, (hybrid) not previously reviewed. Here, different hybrid are reviewed, including (1) thermochemical hydrolysis pre-treatment, using an alkaline acid addition enhance solubilization cells production; (2) high-pressure homogenizer combining mechanical treatment; (3) ultrasound capable solubilizing organic compounds mechanisms, such as fast effective disruption increasing effect (NaOH) (4) microwave which enhances at least 20% comparison performance each separate process; (5) (MW) peroxidation (SSs), quickly (<5 min) disintegrated MW irradiation 80 °C; (6) ozone peroxides powerful oxidizing agents; (7) pulsed electric field (PEF) pretreatment. All literature findings assessed, discussing relevant operation conditions results achieved.

Effect of different biomass on properties of slurry fuel based on petroleum coke and municipal sludge

Petroleum Science and Technology, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 19

Published: Jan. 5, 2025

To produce high-quality slurry fuel from petroleum coke and municipal sludge, the effects of various biomass materials on characteristics were investigated experimentally. The used in this experiment classified into three categories: monosaccharides (e.g., glucose), starch-based potato residue), cellulose-based corn straw, water hyacinth, rice husk, kelp). results revealed significant variations properties influenced by different types their respective proportions. Increasing content led to a decrease solid concentration bubble sludge (bubble-PCSS). However, reduction was moderate with biomass, whereas it pronounced especially kelp. addition significantly improved pseudoplastic rheological slurry. Specifically, when incorporated, flow characteristic index approached 0.7. Optimal stability bubble-PCSS achieved at 2% level biomass. In contrast, using such as kelp, husks, they required 3-4% reach optimal stability, which somewhat less favorable than that
