  • 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 ...

  • 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 ...

  • PSA Technology hits the Fast Lane

    Conventional pressure-swing adsorption (PSA) has been used ito separate and purify industrial gases for more than 35 years. The technology, first developed by ExxonMobil and Air Liquide in the late 1950s, is based upon the capacity of adsorbents to selectively adsorb and desorb particular gases as gas pressure is raised and lowered. PSA is currently used in applications ranging from the ...

  • 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 ...


  • BioLargo`s AOS Filter Wins `Technology Star Award` - New Technology Magazine -The First Word on Oil Patch Innovation

    Advanced disinfectant technology developer sets sights on oil and gas applications A small publicly-listed Santa Ana, Calif.–based company that is developing water purification and advanced disinfectant technologies, all using some form of iodine, sees one of its Edmonton-developed technologies as a way to clean up and even eliminate oilsands mining tailings ...

  • 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 ...

  • Sustainable wastewater separation treatment systems coupled with nutrient and water reducing greywater reuse technologies

    Nationally and internationally, pressure is increasing to introduce nutrient reducing, water conserving and recycling measures for sustainable residential and small community water/wastewater systems. Reports of inadequate water quality and quantity are being reported daily. Over the past thirty years the federal government and State of Alaska have invested over 4 billion dollars installing piped ...


  • Rental GAC Equipment Provides Quick, Feasible Option for Addressing Water Problems

     Municipal drinking water providers looking to quickly come into regulatory compliance or to solve other potable water problems where activated carbon adsorption vessels are the answer sometimes turn to rental equipment as a quick remedy. As the efficiency and cost factors are evaluated over time, the rented vessels can be purchased or upgraded as a permanent drinking water purification ...

  • Micro-aeration for sulfide removal in anaerobic treatment of high-solid wastewater: a pilot-scale study

    The presence of sulfur compounds (e.g. protein, sulfate, thiosulfate, sulfite, etc.) in the feed stream generates highly corrosive and odorous hydrogen sulfide during anaerobic digestion. The high sulfide level in the biogas stream is not only poisonous to many novel metal catalysts employed in thermo-catalytic processes; but also reduces the quality of methane as a renewable energy. This study ...

  • Case Study: 3 pilot projects sponsored by the European Union - LIFE-Program

    Certain waste waters - such as streams from food and beverage industries, leachate waters from municipal waste dumping sites or drinking water purification - are invariably putting highly problematic strains on the environment. Many years of basic research as well as comprehensive test runs with a technical scale demonstration unit model have shown that the Ultrasonic Systems GmbH (USS) is in the ...


  • Case-study - Utilising waste heat for water production and climate control

    Water purification is needed to produce high quality water for consumption, agriculture and industrial needs. Conventional water treatment processes, like distillation and reverse osmosis, consume vast amounts of energy. However, there is a large potential for significant reductions in energy consumption and CO2 emissions in this sector. It can be achieved by the exploitation of waste heat for ...

  • TB 56: Power plant in thailand uses liqui-cel® membrane contactors to remove co2 from water

    A major power plant in Thailand is using Liqui-Cel® Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel Contactors are being used to lower the CO2 inlet into an Ionpure EDI system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. ...
