Antimicrobial Contamination Removal from Environmentally Relevant Matrices: A Literature Review and a Comparison of Three Processes for Drinking Water Treatment

The effectiveness of conventional water treatment technology in preventing the dissemination of antimicrobial contamination has been questioned due to significant rates of antibiotic resistance elements found both in solid wastes and in effluents. This implies that preventive efforts must cover both solid waste quality and effluent quality monitoring. This article presents a review of the occurrence data for a number of antibiotics and antibiotic resistance carriers along with the effectiveness of conventional and advanced technologies in the removal of antimicrobial contamination from various matrices. Although the current literature suggests that the advanced oxidation processes are more promising, cost viable oxidant doses may not be sufficient to reach targeted removal efficiencies especially in biosolids and manure. As a result, antimicrobial contamination can inevitably reach natural waters and contaminate drinking water sources. In this context, a comparison of the effectiveness of three oxidation processes on the removal of a resistance carrier bacterial plasmid DNA was studied. The relative effectiveness of ozonation or heterogeneous photocatalysis over conventional chlorination was demonstrated.

Gold nanoparticles for cleaning contaminated water

Pollutants in the form of heavy metals, fertilizers, detergents, and pesticides have seriously reduced the supply of pure drinking water and usable water. Gold metal has intriguing potential to deal with the water pollution problem, as recent research on several fronts is advancing the concept of nanoscale gold as the basis for cost‐effective nanotechnology‐based water treatment. Nano‐gold has special properties, such as enhanced catalytic activity, visible surface plasmon resonance color changes, and chemical stability, that make it more useful than other materials. This Perspective article highlights the current use of gold nanoparticles for the efficient removal and the selective and sensitive detection of a variety of pollutants in water. The challenges in further developing nano‐gold to address water contamination are discussed, which should stimulate future research into improved removal and detection of undesirable chemical compounds. © 2013 Society of Chemical Industry     

Desalination in the gaza strip: drinking water supply and environmental impact

More than 90% of the population of the Gaza Strip depends on desalinated water for drinking purposes. About 90% of the groundwater is unacceptable for drinking as a result of contamination by nitrate and chloride. One of the major options for resolving the water problems is the utilization of desalination technology for both sea and brackish water. The objective of this article is to address desalination water management in its embryonic stage in the Gaza Strip. The sources of drinking water supply, distribution system and the environmental impact of brine water will be fingered in detail. Desalination facilities range from large seawater plants to small brackish desalination units on a home scale. Governmental, non-governmental and private desalination plants are common. The distribution system of desalinated water is a responsibility of governmental, non-governmental, private small community bodies and even individuals. Disposal of brine water is made either directly or indirectly into the sea, sewage system, poor land, channels, wadies, etc. Brine constituents have an adverse impacton the surrounding environment, e.g., sea life, soil, wastewater treatment plants and the groundwateraquifer. The lack of real environmental impact assessments, especially for mid- and home-scale units may lead to a deterioration of the environment. The fragmentation of the responsibilities of water desalination, distribution of desalinated water and the disposal of brine water suggest that urgent action should be taken (e.g., legislation or establishment of a supervisory body). In other words, strict policies and management actions are to be taken in order to alleviate the health and environmental impact of an important and uncontrolled new system.     

漏氯吸收液中氯化亚铁的两种检测方法的探讨

液氯泄露是自来水厂重大安全事故之一,因此,漏氯安全装置成为上级主管部门和水厂安全生产监查的主要项目。中山市稔益水厂安装的是氧化还原型漏氯安全吸收装置,装霞内的氯气吸收液主要成分是氯化亚铁。水厂规定对该装置的氯化亚铁浓度进行定期检测,频率为每月一次。因《生活饮用水标准检验方法》中没有氯化亚铁的测定方法,因此,氯化亚铁的检测需参考《生活饮用水标准检验方法》铁的检测方法以及《工业氯化铁国家标准》的检测方法,通过对两种氯化亚铁的检测方法进行对比分析,找出最适合的方法作为本水厂的日常检测方法。     

Arsenic removal by coagulation and filtration: comparison of groundwaters from the United States and Bangladesh

Arsenic contamination of drinking water is a concern in many parts of the world. In the United States, the Environmental Protection Agency recently reduced the maximum contaminant level of arsenic in drinking water from 50 to 10 μ/L (ppb). In Bangladesh the arsenic concentration in drinking water can be as high as hundreds of parts per billion while the maximum contaminant level is 50 ppb. Consequently, there is a great need for new cost-effective methods to remove arsenic from drinking water. Here arsenic removal by coagulation and filtration was investigated using groundwater from a city in southern Colorado in the United States and from Sonargaon in Bangladesh. The results of the bench-scale experiments conducted indicate that coagulation with ferric ions followed by filtration is effective in reducing arsenic concentration in the water tested. However, the actual efficiency of removal is highly dependent on the raw water quality. Further, addition of a polyelectrolyte coagulant aid may lead to improved permeate fluxes during tangential flow microfiltration but has little effect on the residual arsenic concentration.
