Nowadays, synthetic diamond has been studied for its application in wastewater treatment, electroanalysis, organic synthesis and sensor areas; however, its use in the water disinfection/purification is its most relevant application. The new electrochemistry applications of diamond electrodes open new perspectives for an easy, effective, and chemical free water treatment. This article highlights...

High-efficiency, affordable, and low energy water disinfection methods are in great need to prevent diarrheal illness, which is one of the top five leading causes of death over the world. Traditional water disinfection methods have drawbacks including carcinogenic disinfection byproducts formation, energy and time intensiveness, and pathogen recovery. Here, we report an innovative method that a...

Disinfection of drinking water is commonly carried out by chlorination, however research has shown this method to be ineffective against certain rotozoan, viral and biofilm forming microorganisms. Furthermore, chlorination can result in the formation of mutagenic disinfection by-products. emiconductor photocatalysis may be a possible alternative to chlorination for point-of-use drinking water d...

background: the goal of this study was to survey the total residual chlorine and chloroform in the water distribution system of isfahan, iran, and zoning of obtained results using gis. methods: in this cross-sectional study, total residual chlorine was tested in the sampling points of the water distribution system of isfahan and chloroform was measured with standard methods and after transferri...

The potential for generation of disinfection byproducts (DBPs) in swimming pools is high due to the concentrations of chlorine required to maintain adequate disinfection, and the presence of organics introduced by the swimmers. Health Canada set guidelines for trihalomethanes (THMs) in drinking water; however, no such guideline exists for swimming pool waters. Exposure occurs through ingestion,...

Decentralized, energy-efficient waste water treatment technologies enabling water reuse are needed to sustainably address sanitation needs in water- and energy-scarce environments. Here, we describe the effects of repeated recycling of disinfected blackwater (as flush liquid) on the energy required to achieve full disinfection with an electrochemical process in a prototype toilet system. The re...

production. Quarantine measures are necessary to avoid spread of disease to disease-free areas. R. solanacearum has been shown to contaminate watercourses from which crop irrigation is then prohibited causing further potential losses in yield and quality. The bacteria also spread via surfaces that diseased seed potatoes come into contact with. This study showed bactericidal activity of chlorine...

Biological invasions through ships’ ballast water create threats to the environment and to the human health and thus, need to treat prior to the discharge. In this study, an innovative electro-disinfection reactor system is developed and optimized for disinfection of E. coli in ballast water to achieve the International Maritime Organization’s (IMO) guideline, 250 CFU/100ml. Optimized hydraulic...

We evaluated the eficacy of povidone-iodine treatments in preventing vertical transmission of Flavobacterium psychrophilum in the eggs of masu salmon Oncorhynchus masou, Japanese char Salvelinus pluvius, coho salmon O. kisutch and rainbow trout O. mykiss. When newly spawned eggs were immersion-chalenged with F. psychrophilum (> 10 CFU/mL) and subsequently disinfected with povidone-iodine (50 pp...

The failure to reduce the Campylobacter contamination of intensively reared poultry may be partially due to Campylobacter resisting disinfection in water after their internalization by waterborne protozoa. Campylobacter jejuni and a variety of waterborne protozoa, including ciliates, flagellates, and alveolates, were detected in the drinking water of intensively reared poultry by a combination ...
