How to clean your UV lamp

by Alpha Cure (UK)  (Aug. 24, 2015)

Cleaning Your UV Lamps and System It is extremely important to maintain your UV lamps and system to avoid problems which could prevent your UV lamp from curing. Firstly when handling a UV lamp we strongly recommend that you wear gloves, this will prevent contaminants such as fingerprints from sticking to the surface of the quartz body. To clean ...

Co‐exposure of ZnO nanoparticles and UV radiation to Daphnia magna and Danio rerio: Combined effects rather than protection

by John Wiley & Sons, Ltd.  (Aug. 15, 2015)

The application of nanoparticles (NPs) in consumer products has been increasing over the past few years. Their release to the environment is likely to happen at any stage of production or usage of NPs‐containing products. Zinc oxide nanoparticles (ZnO‐NP) are among the most used NPs in the market due to its intrinsic properties, such as UV ...

Photo‐induced toxicity of Deepwater Horizon slick oil to blue crab (Callinectes sapidus) larvae

by John Wiley & Sons, Ltd.  (Jul. 21, 2015)

The 2010 Deepwater Horizon oil spill resulted in the accidental release of approximately 700 million L of crude oil into the Gulf of Mexico. Photo‐induced toxicity after co‐exposure to ultraviolet (UV) radiation is 1 mechanism by which polycyclic aromatic hydrocarbons (PAHs) from oil spills may exert toxicity. Blue crab are an important ...

Effect of 10 different TiO2 and ZrO2 (nano)materials on the soil invertebrate Enchytraeus crypticus

by John Wiley & Sons, Ltd.  (May 27, 2015)

Nearly 80% of all the nano‐powders produced worldwide are metal oxides, and among these materials titanium dioxide (TiO2) is one of the most produced. TiO2 toxicity is estimated low to soil organisms, but some studies have shown that TiO2 nanoparticles (NPs) can cause oxidative stress. Additionally, it is known that TiO2 is activated by UV ...

Biodiesel from wastewater: lipid production in high rate algal pond receiving disinfected effluent

by IWA Publishing  (Apr. 27, 2015)

The production of different species of microalgae in consortium with other micro-organisms from wastewaters may represent an alternative process, to reduce the costs, for obtaining biofuels. The aim of this study was to evaluate the influence of pre-ultraviolet disinfection (UV) in the production of lipids from biomass produced in high rate ...

Comparison of ultraviolet light emitting diodes with traditional UV for greywater disinfection

by IWA Publishing  (Mar. 13, 2015)

The current technological status of ultraviolet light emitting diodes (UV-LEDs) has reached a point where small-scale ultraviolet (UV) water disinfection applications, that is, for greywater reuse appear increasingly promising. This study compares the germicidal and economical aspects of UV-LEDs with traditional UV. Pure cultures and ...

Proven Protection In The World`s First Antimicrobial Classroom

by Waterlogic International Ltd  (Mar. 10, 2015)

The scientists at BioCote® recently ran a live test to measure and compare the number of bacteria in two classrooms in the same primary school. This was a world first as never before had an antimicrobial classroom been put under the microscope. The objective was to see how well BioCote antimicrobial protection performs in the classroom ...

Experimental determination of dose uniformity in the CDTN gamma irradiator

by Inderscience Publishers  (Mar. 6, 2015)

This paper describes an experimental study of dose uniformity within a container used for products irradiation, in the gamma irradiation facility at Nuclear Technology Development Center (CDTN). The CDTN is a research institute of the National Nuclear Energy Commission (CNEN), Brazil. Polymethylmethacrylate (PMMA) dosimeters were used in order to ...
