Hazard and vulnerability evaluation of water distribution system in cases of contamination intrusion

Kunlun XIN, Tao TAO, Yong WANG, Suiqing LIU

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 6,   Pages 839-848 doi: 10.1007/s11783-012-0409-8

Abstract: In this paper, it proposed an index system for hazard and vulnerability evaluations of water distribution networks, based on the simulation of contamination events caused by pollutant injections at different junctions. It attempted to answer the following two questions in the case of contamination events: 1) Which are the most hazardous junctions? 2) Which are the most vulnerable junctions? With EPANET toolkit, it simulated the propagation of the contaminant, and calculated the peak concentration of the contaminant and mass delivered at different nodes. According to types of consumers, different weights were assigned to the consumer nodes for assessing the influence of the contaminant on the consumers. Using the method proposed herein, both the hazard index and vulnerability index were calculated for each node in the pipe network. The presented method was therefore applied to the water network of the city of Zhenjiang, which contains two water plants, two booster pump stations with storage tanks. In conclusion, the response time, the relationships between the peak concentration of contaminant and the total absorption are the most important factors in hazard and vulnerability evaluation of the water distribution network.

and bacteriophage MS2 disinfection by UV, ozone and the combined UV and ozone processes

Jingyun FANG,Huiling LIU,Chii SHANG,Minzhen ZENG,Mengling NI,Wei LIU

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 4,   Pages 547-552 doi: 10.1007/s11783-013-0620-2

Abstract: However, less is known about the disinfection performance of UV and ozone (UV/ozone) coexposure and sequentialUV-followed-by-ozone (UV-ozone) and ozone-followed-by-UV (ozone-UV) exposures.In this study, inactivation of and bacteriophage MS2 by UV, ozone, UV/ozone coexposure, and sequentialUV-ozone and ozone-UV exposures was investigated and compared.Little enhancement on inactivation was found after the sequential UV-ozone or ozone-UV exposures.

Photochemical indicators of ozone sensitivity: application in the Pearl River Delta, China

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 6, doi: 10.1007/s11783-016-0887-1

Abstract: Six popular ratios indicating ozone-precursor sensitivity, HCHO/NO , H O /HNO , O /NO , O /NO , O /HNOWRF-Chem was used to study a serious ozone episode in fall over the Pearl River Delta (PRD).All indicators produced good representations of the elevated ozone hours in the episode on 6 NovemberThe ozone episode on 16 November 16 2008 was used to independently verify the results, and it was foundthat only H O /HNO and H O /NO were able to differentiate the ozone sensitivity regime well.

Combined process of biofiltration and ozone oxidation as an advanced treatment process for wastewater

Xinwei LI,Hanchang SHI,Kuixiao LI,Liang ZHANG

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 6,   Pages 1076-1083 doi: 10.1007/s11783-015-0770-5

Abstract: The effluent of a wastewater treatment plant was treated in a pilot plant for reclaimed water production through the denitrification biofilter (DNBF) process, ozonation (O ), and biologic aerated filtration (BAF). The combined process demonstrated good removal performance of conventional pollutants, including concentrations of chemical oxygen demand (27.8 mg·L ) and total nitrogen (9.9 mg·L ) in the final effluent, which met the local discharge standards and water reuse purposes. Micropollutants (e.g., antibiotics and endocrine-disrupting chemicals) were also significantly removed during the proposed process. Ozonation exhibited high antibiotic removal efficiencies, especially for tetracycline (94%). However, micropollutant removal efficiency was negatively affected by the nitrite produced by DNBF. Acute toxicity variations of the combined process were estimated by utilizing luminescent bacteria. Inhibition rate increased from 9% to 15% during ozonation. Carbonyl compound concentrations (e.g., aldehydes and ketones) also increased by 58% as by-products, which consequently increased toxicity. However, toxicity eventually became as low as that of the influent because the by-products were effectively removed by BAF. The combined DNBF/O /BAF process is suitable for the advanced treatment of reclaimed water because it can thoroughly remove pollutants and toxicity.
