  • Rapid Start Lamps Vs Mercury Arc Lamp

    We have recently had a little bit of confusion between our Rapid Start lamps and our Mercury Arc Lamps and their differing warranties. So to clear up some of your concerns our Production Director Richard Cherry explains how they differ: “It is true, a Rapid Start Lamp is just another version of a Mercury Arc Lamp. However, we add a different fill gas to ...

  • Efficacy of vacuum ultraviolet photolysis for bromate and chlorate removal

    We introduce vacuum ultraviolet (VUV) photolysis at 172 nm as a more efficient process for bromate and chlorate removal than conventional ultraviolet (UV) photolysis at 254 nm. We discuss the effects of pH and coexisting salts on VUV photolysis. In experiments at various pH levels, the VUV photolysis performance decreased in the alkaline region for pH above 7. Furthermore, nitrate and inorganic ...

  • Mercury – The Facts, Myths and Clean Up Tips!

    Mercury, the facts. Mercury is an element (Hg on the periodic table) found naturally in the environment. Mercury emissions can come from both natural and man-made sources. It is commonly used in mercury arc lamps for UV curing, however this is a very minimal amount (as little as 5mg) and is used in the lamp to increase the voltage. Due to the harmful effects of Mercury, many ...

  • UV disinfection of stabilization pond effluent: a feasible alternative for areas with land restriction

    The purpose of this research was to determine the feasibility of a UV photoreactor for the disinfection of effluent from a polishing pond following a UASB reactor treating domestic wastewater. For this, a 20 mm diameter photoreactor (20.7 litre volume) equipped with four 30 W submerged low-pressure mercury arc lamps was used. Three tests with contact times and doses ranging from 45 to 90 s and ...

  • Ultraviolet irradiation combined with manganese ore catalyzed ozonation of 4-chlorophenol in aqueous solution

    We have investigated ultraviolet (UV) irradiation combined with manganese ore (MO) catalyzed ozonation of 4-cholorophenol (4-CP) in aqueous solution. The preliminary results showed UV irradiation and MO had a strong synergetic catalytic effect on ozonation. We also studied the effect of UV lamp power, MO dosage, O3 dosage, initial 4-CP concentration, pH value and temperature. The results showed ...

  • Lehigh Valley Environmental Conference - A Success Story

    On September 20th, the Greater Lehigh Valley Chamber of Commerce (GLVCC) along with Avogadro Environmental Corporation and the Air & Waste Management Association (AWMA) held the Lehigh Valley’s First Annual Environmental Innovations Conference. The idea started out small and quickly grew as more and more companies expressed interest in having a conference that was focused on local industries and ...

  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...
