  • Pressure transmitters: It’s class that counts

    KELLER would like to do away with DIN standards. The company is backing the introduction of an accuracy class, as it did for pressure gauges. The conditions under which the class is complied with are described in specifications. The new EC standards make it more difficult for companies to manufacture their own transmitter electronics. Changing from OEM transducers to OEM transmitters is ...

  • Growth mechanism and optical properties of zinc oxide thin film

    Zinc oxide (ZnO) thin films were successfully deposited on glass substrate by radio frequency (RF) sputtering technique. One set of the samples was annealed in open air at temperatures of 423 K, 573 K and 723 K for one hour while another set of samples was annealed under nitrogen atmosphere for the same duration of time and temperature as the other set. A growth mechanism for thin film growth by ...

  • The analysis of magnetic controlled DC sputtering AZO films

    The Al–doped zinc oxide (AZO) transparent conducting thin films were deposited by the use of magnetic controlled DC sputtering method. To obtain best process parameters, we compare and analyse different process parameters like working pressure and substrate temperature, and properties of AZO films with DC sputtering. The transmittance of AZO film is over 85% at visible region (380∼800 nm). Blue ...

  • Microalgae growth for nutrient recovery from sludge liquor and production of renewable bioenergy

    Proof-of-concept has been demonstrated for a process that will utilize nutrients from sludge liquor, natural light, and CO2 from biogas to grow microalgae at wastewater treatment plants. This process will reduce the impact of returning side-streams to the head of the plant. The produced algae will be fed to anaerobic digesters for increased biogas production. Dewatering of anaerobically digested ...

  • Helping veolia transform waste into bio-fuel case study

    LIPODAN, a VEOLIA company, is a plant for recycling grease, food grease and used oil which is collected from restaurants, from gas stations, car garages, bus companies and similar locations. The plant treats 12,000 Tons of organic oils and 6,000 Tons of mineral oil per year. For recycling, the plant is using the LIPOVAL process. The oils are first converted to LIPOFIT, an ...

  • Wastewater Level Measurement Techniques

    Level monitoring and control is a fundamental requirement in any wastewater treatment process. You will find level instrumentation installed at even the simplest treatment plants for pump control, chemical storage tanks and process level controls or alarms. Operators have only limited or emergency control over treatment plant influent, so level controls and instrumentation play an important role ...

  • Boiler feedwater deaerators

    The thermophysical deaerator is by far the most applied technology when oxygen and carbon dioxide in Boiler Feed Water must be reduced to negligible concentrations Bono ARTES has inherited the experience in the design of Deaerators that started up within the BONO Group in 1959. The Boiler Feed Water, if in equilibrium with the atmosphere, may contain significant levels of corrosive gases, mainly ...

  • Improved efficiency of InGaN/GaN light–emitting diodes with Al–doped zinc oxide using dual–plasma–enhanced metal–organic chemical vapour deposition system

    We have reported aluminium doped zinc oxide (AZO) film grown on sapphire substrate using dual–plasma–enhanced metal–organic chemical vapour deposition (DPEMOCVD) system. The crystalline quality, surface morphology, optical properties, and electrical characteristic of AZO film depend on the deposition temperature and Al content. The 185°C–deposited and 2.88 at%–Al–doped AZO film shows a strong ...

  • Limits of UV disinfection: UV/electrolysis hybrid technology as a promising alternative for direct reuse of biologically treated wastewater

    Although UV irradiation represents an energy efficient disinfection method, bacterial regrowth in UV irradiated secondary effluents is a serious problem for their direct reuse (e.g., for domestic or irrigation purposes). The decrease of the lethal UV fluence caused by coverings (scaling and biofouling) on quartz sleeves of UV lamps and/or fluctuating specific water parameters (suspended solids, ...
