Rapid water disinfection over a Ag/AgBr/covalent triazine-based framework composite under visible light

26-May-2018 | Liuyi Li; Xiaofen Li; Zhi Cheng; Jinhong Bi; Shijing Liang; Zizhong Zhang; Yan Yu; Ling Wu, Dalton Transactions, 2018

Development of visible-light-induced and rapid water disinfection is of significant importance. Covalent triazine-based frameworks (CTFs) with pre-designable structures and favorable semiconductive behaviors hold great promise for photocatalytic water disinfection. Here, we report an Ag/AgBr/CTF ...

Demonstration of complete bacterial‐killing in water at a very high flow‐rate: Use of a surface‐enhanced hybrid of copper nanoparticle with activated carbon

24-Jul-2017 | Pritam Biswas, Rajdip Bandyopadhyaya, Journal of Chemical Technology & Biotechnology, 2017

Abstract BACKGROUND To address the objective of disinfecting water, copper nanoparticles (Cu‐NPs) have been synthesized and impregnated on activated carbon (AC). This material when packed in a continuous column can potentially satisfy the need of a household‐scale water disinfection ...

Silver nanoparticle impregnated rechargeable polyethersulfone (PES) membrane for biofouling prevention and water disinfection

09-Jun-2017 | Pritam Biswas, Rajdip Bandyopadhyaya, Journal of Chemical Technology & Biotechnology, 2017

Abstract BACKGROUND Biofouling severely limits membrane life and performance. To address the twin challenges of biofouling prevention and water disinfection, silver nanoparticle (Ag‐NP) impregnated, sulfonated polyethersulfone (SPES) membrane was chosen. RESULTS By tuning the degree ...

Sodium chlorate, a major water disinfection byproduct, alters brush border membrane enzymes, carbohydrate metabolism and impairs antioxidant system of Wistar rat intestine

13-Jan-2017 | Shaikh Nisar Ali, Fariheen Aisha Ansari, Aijaz Ahmed Khan, Riaz Mahmood, Environmental Toxicology, 2017

Abstract Sodium chlorate (NaClO3) is a widely used nonselective herbicide. It is also generated as a by‐product during disinfection of drinking water by chlorine dioxide. The purpose of this study was to evaluate the effect of NaClO3 on rat intestine. Adult male rats were randomly divided into ...

Bacterial inactivation of liquid food and water using high‐intensity alternate electric field

18-Nov-2016 | Peng Peng, Yanling Cheng, Hao Song, Tingting Zhang, Shaobo Deng, Erik Anderson, Min Addy, Xindi Zhu, Shiyu Liu, Raym ..., Journal of Food Process Engineering, 2016

Abstract Bacteria contaminated liquid food and water, along with the harmful byproducts from chemical disinfection methods, raise concerns to the public health. This article investigated the inactivation of bacteria in liquid food and water using the pilot‐scale concentrated high intensity ...

Functional Silver‐Silicone‐Nanofilament‐Composite Material for Water Disinfection

13-Sep-2016 | Margrith Meier, Angela Suppiger, Leo Eberl, Stefan Seeger, Small, 2016

The roughness of superhydrophobic silicone nanofilaments (SNFs) is exploited to enlarge the contact area of conventional filter material. As an efficient wetting of the filter material is crucial for water treatment, the wettability of SNFs is readily modified from superhydrophobic to ...

Accelerating the process of solar disinfection (SODIS) by using polymer bags

30-Apr-2016 | Sergio Gutiérrez‐Alfaro, Asunción Acevedo, Manuel Figueredo, Matthias Saladin, Manuel A. Manzano, Journal of Chemical Technology & Biotechnology, 2016

Abstract BACKGROUND Solar water disinfection (SODIS) is a point‐of‐use water treatment that consists of exposing microbiologically‐contaminated water in plastic bottles under sunlight. Replacing bottles with bags can accelerate SODIS process, reduce the costs of transport and distribution, ...

Energy of the Lowest Unoccupied Molecular Orbital, Thiol Reactivity, and Toxicity of Three Monobrominated Water Disinfection Byproducts

01-Mar-2016 | Justin A. Pals; Elizabeth D. Wagner; Michael J. Plewa, Environmental Science & Technology, 2016

Disinfection of drinking water protects public health against waterborne pathogens. However, during disinfection, toxic disinfection byproducts (DBPs) are formed. Exposure to DBPs was associated with increased risk of bladder cancer in humans. DBPs are generated at concentrations below their ...

Water Disinfection Byproducts Induce Antibiotic Resistance-Role of Environmental Pollutants in Resistance Phenomena

29-Feb-2016 | Dan Li; Siyu Zeng; Miao He; April Z. Gu, Environmental Science & Technology, 2016

The spread of antibiotic resistance represents a global threat to public health, and has been traditionally attributed to extensive antibiotic uses in clinical and agricultural applications. As a result, researchers have mostly focused on clinically relevant high-level resistance enriched by ...
