Ultrasonic Disinfection of Wastewater Effluents for High-quality Reuse
Cavitation, induced by ultrasound at low frequencies, is an effective means for the disintegration of bacterial cells. Two effects can be observed: At low ultrasound doses bacteria flocs can be declumped by mechanical shear stresses, and at increased doses ultrasound cavitation has an impact on the cell walls such that they are broken. In lab scale experiments a horn sonotrode operated at 20 kH...
متن کاملEffect of UV light disinfection on antibiotic-resistant coliforms in wastewater effluents.
Total coliforms and total coliforms resistant to streptomycin, tetracycline, or chloramphenicol were isolated from filtered activated sludge effluents before and after UV light irradiation. Although the UV irradiation effectively disinfected the wastewater effluent, the percentage of the total surviving coliform population resistant to tetracycline or chloramphenicol was significantly higher th...
متن کاملDisinfection of Primary Municipal Wastewater Effluents Using Continuous UV and Ozone Treatment
UV radiation and ozonation were investigated as disinfection alternatives for the wastewater treatment plant. The inactivation of total and fecal coliforms using ozone and ultraviolet radiation as separate treatments was evaluated. Different ozone concentrations (3 to 40 mg O3/L) were applied and UV fluencies ranging from 8.5 to 12 mJ/cm at different pH values (from 5 to 9) were tested. Best re...
متن کاملinfluence of physical quality changes on uv disinfection of wastewater
ultraviolet radiation (uvr) has been accepted as an attractive alternative to chlorination for the disinfection of wastewater. in this study the effluent from sahebgaranieh treatment plant was subjected to changes in uv transmission and turbidity in order to correlate these commonly measured parameters with the performance of a submerged -uv- reactor employed in disinfecting the effluent. studi...
متن کاملEndodontic disinfection – tsunami irrigation
XX There are enormous differences in opinion regarding the potential to three-dimensionally clean a root canal system. Elimination of pulpal tissue, bacteria when present, and their related breakdown products is directly influenced by a series of procedural steps that comprise start-to-finish endodontics. Regrettably, there is no single beacon of light to brightly illuminate the most proven cli...
