  • Advanced technology for water purification by heterogeneous photocatalysis

    The TiO2 photocatalytic degradation of 2,4-dichlorophenol (2,4-DCP) and pentachlorophenol (PCP) was examined using a prototype photoreactor fabricated by Nulite. The degradation of both pollutants proved very efficient as in 12 min it was possible to bring the concentration of 2,4-DCP from 10 to 0.5 p.p.m. and in a separate experiment the concentration of PCP from 100 to 0.5 p.p.b. The effect of ...

  • Thermal waste gas purification of siliceous organic compounds - Case Study

    Example: Electrical industry Similar tasks: Electronic industry, Coating, Waste management When coating mica insulation materials, peaks of high contamination occur. The exhaust air containing organic compounds generates excess heat when oxidised in the regenerative thermal oxidiser (RTO). The properties of ceramic honeycomb blocks allow for the storage of that excess heat, for the ...

  • Recovery of stainless steel pickle liquors: Purification vs. Regeneration

    Pickling Chemistry During finishing of stainless steel, the metal is typically rolled and then annealed to achieve the desired structure and material properties. Because annealing is carried out in the presence of air, a film of oxide consisting mainly of chromium oxide (Cr2O3), ferrous oxide (FeO), and manganous oxide (MnO) forms on the surface of the steel. The Cr2O3 content is normally ...

  • Challenges of Fuel Gas Purification for Cogeneration Under Stringent Regulatory Requirements

    ABSRTRACTInland Empire Utilities Agency (IEUA), a municipal water district based in Chino, CA is currently executing a cogeneration power project, titled Renewable Energy Efficiency Project (REEP) at the Regional Plant No.5 (RP-5), which showcases a variety of innovative technologies for the power production. The project involved many innovative technologies, most of which are still in the ...

  • Wastewater sterilization (purification): completely new method “vortex layer machine”

    The purification and safe disposal (neutralization) of industrial waste water effluents represent a very important ecological problem. The principal problem or requirement involves reducing the concentration of harmful impurities to concentration levels below their maximum allowable concentration limits. In fulfilling this requirement the amount of fresh water consumption needed to maintain the ...

  • Air uality in IVF Labs

    Since the birth of the first baby from in-vitro fertilisation (IVF) in 1978, Assisted Reproductive Technology (ART) has grown in importance as techniques and success rates have continued to improve. Put simply, IVF involves mixing sperm and egg in a lab to create an embryo which is then replaced in a woman's womb to develop normally with success being measured in terms ...

  • Recovering Valuable Chemicals from Air Emissions

    Air emissions in many cases are a waste of valuable natural resources that should have become useful chemicals. In some cases the economic payback from recycling/reuse of air emissions can be almost as much a motivation to control air pollution as government regulations. Examples of recycling and reuse of air emissions are sulfur oxides emissions that can be made into sulfuric acid, cement ...


  • Chemical Air Pollution in the Clinical Research Environment

    There has been a revolution in awareness of chemical air pollution in research laboratories. I could tell you several 'horror stories' of casual exposure to mercury vapour, benzene and chromic acid (the ultimate glassware cleaning agent) among innocent biomedical PhD students (including myself) in the 1970s. But researchers in hospitals, and other laboratories can never afford to be complacent ...

  • Roof over primary settling tanks to prevent air pollution and odours

    The Wastewater Purification Plant (EDAR) in Cambrils, Tarragona, was the setting for a solution deployed by Bioconservación, a gas absorption and air purification specialist. The project involved covering over the settling tanks to prevent hydrogen sulphide dissolved in the water from polluting the surrounding air. The H2S (hydrogen sulphide) dissolved in water as it arrives at the tank in ...

  • Control of Aerosol Contaminants in Indoor Air: Combining the Particle Concentration Reduction with Microbial Inactivation

    ABSTRACT An indoor air purification technique, which combines unipolar ion emission and photocatalytic oxidation (promoted by a specially designed RCI cell), was investigated in two test chambers, 2.75 m3 and 24.3 m3, using nonbiological and biological challenge aerosols. The reduction in particle concentration was measured size selectively in realtime, and the Air Cleaning Factor and the Clean ...

  • AERZEN provides energy efficient process air generation in the Kötz wastewater treatment plant

    The Kötz wastewater treatment plant, located a few kilometres south of Günzburg, was designed for a population equivalent of 45,000. About 20,000 inhabitants are connected at present. Due to the additional discharge of industrial wastewater, the average daily load corresponds to a population equivalent of about 35,000. The wastewater treatment plant works according to the ...
