This research examines whether ultrasonic waves can enhance the hydrolysis, stability, and dewatering of activated sludge from raw urban wastewater. Sampling physical examination that was returned to aeration pond were carried out using guided at frequencies 30 50 kHz for periods 0.5, 1, 3, 5, 10, 15, min. Various tests, including volatile suspended solids, inorganic resistant time, capillary suction total soluble advance further processes stabilization, dehydration samples. According observations, solids a frequency t=15 min raised by 72%. The time in 1 demonstrated drop 29 22%, respectively. It is crucial consider that, 10 kHz, greatest efficiency found. yielded optimum conditions. Finally, artificial neural networks (ANN) are utilized propose predictive models concentration, results also very accurate (MAE=1.37%). Regarding computational costs, ANN took approximately 5% spent on experiments.

The concentration of amoxicillin, one the most prescribed antibiotics, has increased in water sources. This investigation aimed to explore enzymatic biodegradation amoxicillin (AMX) from wastewater through H2O2 stimulation catalase-positive bacteria a 5-liter sequential batch reactor (SBR). bacterial consortium was first adapted by slowly increasing for 12 days. results showed that biomass well acclimatized degradation AMX wastewater. Real with TDS and COD concentrations 20,000 mg/L 300 mg/L, respectively, nutrient solution C/N/P ratio 1/10/100 provided as feed SBR. After 22 h reaction, removal rate 98.9% finally reached 99.6% on 25th day operation. When content suddenly 700 decomposition efficiency decreased 90.3%, next operation cycle, 98.1%. key species involved system were Pseudomonas spp., Bacillus Klebsiella oxytoca. sludge volume index total solid produced SBR analyzed be 71 mL/g 10.2 g/L, respectively. According findings, is best systems high-content
