Zinc oxide nanoparticles (ZnO NPs) production and usage might lead to a large discharge of ZnO NPs into the natural environment, raising concerns of pollution and ecological security. The effects of ZnO NPs on waste activated sludge hydrolytic acidification and microbial communities were studied in semi-continuous fermentation systems. The fermentation performance of eight ZnO NPs concentrations including ZnO NPs normal [0.

Salinity enhanced soluble protein and polysaccharide (SB-EPS) release which was 4.04 times (protein) and 1.

- * They used a special chemical called Potassium Monopersulfate (PMS) that helped to make the fermentation process better by increasing important substances in the sludge.
- * As a result, they produced a lot more short-chain fatty acids (which are good for energy), and the activity of certain useful enzymes increased significantly compared to natural fermentation.
