20.500.12556/RUL-146365 A review on rotary generators of hydrodynamic cavitation for wastewater treatment and enhancement of anaerobic digestion process Pregled rotacijskih generatorjev hidrodinamične kavitacije za čiščenje odpadne vode in izboljšanje procesa anaerobne presnove The issue of ever-increasing amounts of waste activated sludge (WAS) produced from biological wastewater treatment plants (WWTPs) is pointed out. WAS can be effectively reduced in the anaerobic digestion (AD) process, where methanogens break down organic matter and simultaneously produce biogas in the absence of oxygen, mainly methane and CO2 . Biomethane can then be effectively used in gas turbines to produce electricity and power a part of WWTPs. Hydrodynamic cavitation (HC) has been identified as a potential technique that can improve the AD process and enhance biogas yield. Rotary generators of hydrodynamic cavitation (RGHCs) that have gained considerable popularity due to their promising results and scalability are presented. Operation, their underlying mechanisms, parameters for performance evaluation, and their division based on geometry of cavitation generation units (CGUs) are presented. Their current use in the field of wastewater treatment is presented, with the focus on WAS pre/treatment. In addition, comparison of achieved results with RGHCs relevant to the enhancement of AD process is presented. wastewater treatment waste activated sludge anaerobic digestion biomethane rotary generator of hydrodynamic cavitation hidrodinamska kavitacija odpadna voda aktivno blato anaerobna presnova biometan rotacijski generator hidrodinamske kavitacije true false true Angleški jezik Slovenski jezik Članek v reviji 2023-05-25 09:55:55 2023-05-25 09:56:00 2025-05-14 14:04:27 0000-00-00 00:00:00 2023 0 0 27 str. iss. 2, art. 514 Vol. 11 2023 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 628.3 2227-9717 10.3390/pr11020514 141131011 processes-11-00514.pdf processes-11-00514.pdf 1 1962098A220544145F2AC458D28990C4 838ef27490e6a0f2323aa16c459794dd8fc65356545714e273b3e98289bd538a 4ef659aa-fadc-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169539 https://www.mdpi.com/2227-9717/11/2/514 1 4f34307e-fad1-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169537 Fakulteta za gradbeništvo in geodezijo Fakulteta za strojništvo 0 0 0
