Conventional disinfection techniques, relying on a single step, often fail to directly eliminate microorganisms, instead causing them enter viable but nonculturable (VBNC) state. However, microorganisms in the VBNC state retain metabolic activity and can reactivate under suitable conditions, representing “hidden source of contamination” that threatens drinking water safety. This study fundamentally assessed feasibility combined methods by integrating UV254 with disinfectant (NaClO, PAA, PDS) for inactivating Pseudomonas aeruginosa (P. aeruginosa), an opportunistic pathogen has been widely detected supply systems. The number culturable cells was determined using heterotrophic plate counting (HPC) method, quantified our recently developed qPCR approach. Quantitative analyses showed effectively reduce both several orders magnitude compared step. Notably, P. aeruginosa, after 30 min UV/NaCIO treatment, below detection limit (3.191 log CFU/mL) PMA-qPCR. reactivation experiment also confirmed did not 16 h UV/NaClO treatment controlled laboratory conditions. higher capacity be attributed generation reactive radicals. highlighted as promising approach inactivation bacteria state, yet further studies are needed before application considered minimizing city utility processing or high-risk building distribution

Abstract This study integrates multi-effect distillation (MED), multi-stage flash (MSF) evaporation, and solar interface evaporation technologies to enhance water purification processes. We evaluate the material performance of evaporators, with a particular focus on managing energy balance in evaporation. The research further develops thermal regulation photothermal materials maximize light absorption, minimize heat loss, speed up steam conversion. employ novel approach using corn starch ionic liquid-modified silica hydrogels, noted for their hydrophilicity broad-spectrum absorption. goal is assess these hydrogels conversion efficiency salt resistance, examining across various media—pure water, highly saline oily wastewater—and effectiveness purifying industrial sewage. Monomer [VEIm]Br cross-linking agent polymerization occurred prepare obtained SiO 2 – PILs.Ag / PPy PILs surface polypyrrole Ag particles presenting three-dimensional porous structure able absorption performance, between 200-2500 nm range rate as high 90%. Experiments proved introduction liquid grafted mechanism improve insulation resistance actual wastewater provide strategy.
