  • Understanding the 3 Types of Arsenic Removal Used for Wastewater

    With the onset of the Industrial Revolution and the development of internal combustion engines and new manufacturing technologies, fresh water became an essential raw material not only for production, but for cooling purposes in manufacturing processes. However, when fresh water is used in an industrial process, it creates industrial wastewater composed of a variety of chemicals and other raw ...

  • Electrochemical oxidation of m-cresol purple dye in aqueous media

    The present investigation showed that the indicator dye m-cresol purple (mCP) was degraded in a laboratory scale, undivided electrolysis cell system. A platinum anode was used for generation of chlorine in the dye solution. The influence of supporting electrolyte, applied voltage, pH, initial dye concentration and temperature were studied. The ultraviolet-visible spectra of ...

  • Case study - Oxidizer rebuild

    Industry Service and Maintenance Problem Anguil was called in to provide an engineering evaluation of a competitor's RTO that was suffering from visible deterioration and 'hot spot' issues. Due to the customer's production schedule, an internal inspection was not possible prior to the plant shutdown for repairs. Action ...

  • Investigation of UV-assisted chlorophenol congeners’ degradation by organic oxidant p-nitrobenzoic acid in basic media

    This research specifically addressed the photodegradation of selected model chlorophenol (CP) congeners, 4-chlorophenol (4-CP), 2,4-dichlorophenol (2,4-DCP), 2,4,6-trichlorophenol (2,4,6-TCP) and pentachlorophenol (PCP), by an organic oxidant, p-nitrobenzoic acid (PNBA), in basic media. The reactions were followed by high-pressure liquid chromatography and gas chromatography–mass ...

  • Understand the Capabilities of Bio-Oxidation

    Biological air-pollution control technology* has been used extensively in Europe for decades and, to a lesser extent, in North America for the past two decades. Most installations in the U.S. have been on air-emission vent streams that were not subject to numerical limits (i.e., ...


  • Treatment of heavy metals by iron oxide coated and natural gravel media in Sustainable urban Drainage Systems

    Sustainable urban Drainage Systems (SuDS) filter drains are simple, low-cost systems utilized as a first defence to treat road runoff by employing biogeochemical processes to reduce pollutants. However, the mechanisms involved in pollution attenuation are poorly understood. This work aims to develop a better understanding of these mechanisms to facilitate improved SuDS design. Since heavy metals ...

  • A laboratory-scale comparison of compost and sand—compost—perlite as methane-oxidizing biofilter media

    Municipal solid waste landfills produce methane, a potent greenhouse gas. A treatment approach is to passively vent landfill gas through a methane-oxidizing biofilter medium, a porous substrate that facilitates the growth of methanotrophic bacteria. Two substrates, compost and a sand—compost—perlite (SCP) mixture, were evaluated in a laboratory-scale experiment for their suitability as biofilter ...

  • Oxidative treatment of diclofenac via ferrate(VI) in aqueous media: effect of surfactant additives

    The potential reaction of diclofenac (DCF) with ferrate(VI) and influences of coexisting surfactants have not been investigated in depth, and are the focus of this study. The results demonstrated that DCF reacted effectively and rapidly with Fe(VI) and approximately 75% of DCF (0.03 mM) was removed by excess Fe(VI) (0.45 mM) within 10 min. All of the reactions followed pseudo first-order ...

  • Rto & recuperative oxidizer pros & cons - Regenerative thermal oxidizer technology

    RTO technology has been developed for large volumes and low VOC concentration air pollution applications. The best example is spray booth exhaust where the volume of exhaust is high and VOC concentration is very low. Regenerative Thermal Oxidizer technology is based on using ceramic media as heat exchangers and switching values. Advantages High thermal efficiency ...

  • Oxidizer operating cost reduction strategies

    The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for both energy conservation and energy cost reduction. ...

  • Control of metal oxide fouling in reverse osmosis

    High levels of iron and manganese, along with large quantities of dissolved gases in the wells created concern for the viability of a conventional desalination design for the proposed City of Camarillo groundwater desalination facility. To identify viable pre-treatment process(es) for the control of metal oxide fouling in reverse osmosis, a 12-month pilot study was undertaken. The pilot study ...

    The Importance of high-quality service for Regenerative Thermal Oxidizer. Safety, efficiency and compliance among pressures facing Regenerative Thermal Oxidizer operators. As any plant or maintenance manager working in a manufacturing environment using volatile organic compounds (VOCs) could tell you, the standards for support of all equipment along the process is critical for safety and ...

  • Upflow anaerobic filter with dual media – a novel concept

     ABSTRACT To overcome two of the main problems intrinsic to upflow anaerobic filters using single media— clogging and biomass washout—a new strategy consisting of two different media is studied. The study is to evaluate the performance of Dual Media Upflow Anaerobic Filter (DM UAF), a novel wastewater treatment unit using synthetic waste as well as primary treated effluent of Common ...
