“…Furthermore, the polyvalent phage isolated from a WWTP succeeded in the removal of different Gordonia and Nocardia species [46]. Excessive sludge-forming caused by filamentous bacteria and EPS secreted by Zoogloea and Thauerea genera is the other problem to tackle in activated sludge systems [47]. The high abundance of EPS prevents the dehydration of sludge through retaining water and subsequently results in the reduction of the sedimentation capacity and biofilm formation.…”

In wastewater treatment plants, the stability of the related microbiota is pivotal for a steady and appropriate operation in biological wastewater treatment (BWT). The interactions between phages, which are high in amounts and diversity, and their particular hosts are significant due to their specificity in this microbial community. As drivers of diversity, phages are capable of changing the microbial structure by affecting host cells. This study aimed to enhance the stability of the functional microbiota, a primary concern of BWT, by evaluating the influence of bioaugmentation with bacteriophage cocktails. The sequencing data revealed significant alterations in the entire microbiome, including microeukaryotes, induced by the bacteriophages. These alterations led to a reduction in opportunistic microorganisms while preserving the beneficial ones. The genus Proteobacteria was found unaffected by three antibiotics in the bioreactor due to its antibiotic-resistant members, leading to its further growth, while the antibiotic-sensitive genus decreased in quantity. Furthermore, the phages notably influenced the metabolic pathway such as nitrogen, carbohydrate, and amino acid metabolisms by eliminating opportunistic microbes and providing improved growth conditions to bacterial species that are essential for effective reactor performance and wastewater treatment.

“…Optimizing the reaction conditions achieved 70% of CIP removal. Luo, Ge, et al (2019) applied a combination of potassium permanganate (KMnO 4 ) and peroxymonosulfate (PMS) for the dewatering of waste activated sludge. This combined technique enhanced sludge dewaterability with capillary suction time decreasing from 73.65 to 24.65 s and water content from 78.96% to 70.47%.…”
