Slightly acidic (pH 5.1) waste sludge with 4.7 % Total Solids (TS) was treated on a laboratory scale pined disc rotary generator of hydrodynamic cavitation (PD RGHC). Influence four rotor discs different number generation units (CGUs) investigated: 8-pins, 12-pins, 16-pins and 8-prism elements. The effect (HC) investigated by analyzing rheological properties, surface tension, dewaterability, particle size distribution. After subjecting the to 30 passes, dewatering ability significantly decreased, resulting in more than two-fold increase Capillary Suction Time (CST). All regimes were successful disintegrating particles smaller sizes. A slight tension measured post cavitation. Cavitated samples displayed zero-shear viscosity, contrast untreated sample, where viscosity noticeably increased as shear stress decreased. HC did not improve methane yield. Statistically significant correlations between physio-chemical properties apparent at low identified. Although there no discernible statistical differences characteristics, some trends are visible among CGU designs warrant further research.

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.

Abstract The land application of sewage sludge from wastewater treatment plants has been recognized as a major source microplastic contamination in soil. Nevertheless, the fate and behavior microplastics soil remain uncertain, particularly their distribution transport, which are poorly understood. This study does bibliometric analysis visualization relevant research publications using CiteSpace software. It explores limited available on topic, highlighting potential for it to emerge hotspot future. Chinese researchers institutions paying great attention this field promoting close academic cooperation among international organizations. Current hot topics mainly involve pollution caused by sludge, well detection, environmental fate, removal presence typically ranging tens thousands hundreds particles (p)/kg, inevitably leads introduction into upon application. In China, estimated annual accumulation due use is approximately 1.7 × 10 13 p.

Future should focus expanding theoretical understanding these soils, enabling development comprehensive risk assessments informed decision‐making management practices.
