  • Is Ultraviolet Ultra Safe?

    With retailers under pressure to meet increasing health and safety standards, it’s no surprise that many of our food & products are coming into contact with Ultraviolet (UV) radiation which is gradually becoming common as a cost effective method of reducing or eliminating pathogens Ultraviolet wavelengths are classified into three general areas: UV-A, UV-B and UV-C. These can be used in ...

  • Ultraviolet Light Oxidation of Free-Chlorine in Water

    Chlorine is the most frequently used chemical for water disinfection. Many industrial and commercial manufacturing facilities cannot tolerate the introduction of chlorine into the process because of contamination and unwanted chemical reactions. Chlorine affects the flavour and odour of drinks and fluids, accelerates corrosion on process vessels and piping, and can also damage delicate process ...

  • Measuring SO2 ship emissions with an ultraviolet imaging camera

    Over the last few years fast-sampling ultraviolet (UV) imaging cameras have been developed for use in measuring SO2 emissions from industrial sources (e.g. power plants; typical emission rates ~ 1–10 kg s−1) and natural sources (e.g. volcanoes; typical emission rates ~ 10–100 kg s−1). Generally, measurements have been made from sources rich in SO2 with high concentrations ...

  • Illuminating Ultraviolet Disinfection for High-Level Reuse in Florida

    Chlorine has been the mainstay of the wastewater disinfection industry for more than 100 years due to its effectiveness, low cost and availability. However, due to various problems associated with chlorine, the Hillsborough County, Florida Water Resource Services Department decided to replace the high-level reuse water chlorine gas disinfection system at the Valrico Advanced Wastewater Treatment ...

  • Unique Ozone and Ultraviolet Water Treatment System

    Euroby Ltd, the sludge treatment specialists, are pleased to announce the signing of an agreement to be the sole UK and Ireland distributor for the unique UVOX range of water treatment  systems.UVOX, as the name suggests, uses a combination of Ultraviolet and Ozone to treat infected and polluted water.Its uniqueness stems from its novel method of first producing ozone by irradiating air with a ...

  • Identification of industrial wastewater by clustering wastewater treatment plant influent ultraviolet visible spectra

    A procedure is proposed which allows the detection of industrial discharge events at the inlet of a wastewater treatment plant without the need for measurements performed at the industry, for special equipment and for exact knowledge of the industrial sewage. By performing UV/Vis measurements at the inlet of a plant and analyzing them with a two-staged clustering method consisting of the ...

  • Disinfection performance testing of high-efficiency ultraviolet water treatment chamber

    When introducing a disinfection product which incorporates new technology, it is essential that the methods and testing used to quantify the performance of those systems follow protocols which are technically sound and which are accepted by the scientific and technical community within the industry. These protocols must be applied precisely and rigorously in order to ensure accurate, repeatable ...

  • Occurrence and dissipation of benzotriazoles and benzotriazole ultraviolet stabilizers in biosolid‐amended soils

    Benzotriazoles (BTs) and benzotriazole ultraviolet stabilizers (BUVSs) are commonly used industrial and household chemicals, but little is known about their dissipation behavior in the soil environment associated with biosolid application. This study investigated the occurrence and dissipation of four BTs (BT, 5‐TT, CBT and XT) and five BUVSs (UV‐326, UV‐327, UV‐328, UV‐329 and UV‐P) in ...

  • Exploring failure mechanisms of near ultraviolet AlGaN/GaN light–emitting diodes by reverse–bias stress in water vapour

    Reliability tests of GaN near UV light–emitting diodes (LED) were investigated by reverse–bias stress in water vapour. Various electrical, optical and material characterisations were performed to examine degradation trend and failure mechanism. On the basis of multiple material analyses, including scanning electron microscopy (SEM) with focus ion beam (FIB), energy dispersive X–ray spectrometry ...

  • UV, a bright future for the water industry

    The use of Ultra Violet (UV) light has now become standard practice in most municipal waste water treatment processes.  Effluent is now starting to be recognised as a valuable resource, not a problem that needs to be dumped. Many waste water facilities are being renamed as water reclamation facilities, and whether the waste water is being discharged into a river, being used to irrigate ...

  • The Benefits Of UV Disinfection In The Pharmaceutical Industry

    The quality standards required for purified water in the production of pharmaceuticals have never been stricter, with manufacturers having to conform to an ever increasing number of international standards. Craig Howarth, Managing Director of Hanovia Limited, introduces a number of interesting new developments in UV technology for disinfection and dechlorination. ...

  • Membrane processing for water treatment in the semiconductor industry

    It is the aim of high-purity water production to either fully eliminate organic and ¡florganic compounds, particles, and microorganisms from the water or to reduce their concentrations to values below the detection limits of the most advanced analysis methods. Currently, this problem is solved by means of a multi-stage process chain, in which membrane technology ...

  • RoHS Directive: Industry Group Challenges Exemption Recommendations

    A group of industry associations has told the European Union Commission it does not agree with recommendations on how to handle Pack 9 exemptions under the Restriction of Hazardous Substances (RoHS) Directive. The Cross-Industry Project, also known as the Umbrella Project, includes over 34 industry associations around the world. The group submitted their feedback in July 2016, shortly ...

  • Industrial and agroindustrial wastes: an echotechnological approach to the production of supported photocatalysts

    Agroindustrial wastes (rice husk, exhausted bark acacia, and tobacco dust) and foundry sands from the iron foundry industry were employed as a support source for photocatalysts. TiCl4 was used as the titanium precursor in the preparation of the supported photocatalysts. The solids were characterized by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX), diffuse ...
