  • What is a Rotary Tube Furnace?

    By definition, a rotary tube furnace is a heat-treating circular furnace, which rotates during heat-treatment. Samples are transported through the furnace in a circular path as they are heated. Rotary tube furnaces generally burn pulverized, solid, gaseous or liquid fuel into its working section, and then the heating gases created flow towards the sample. These furnaces feature a metal drum lined ...

  • 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 ...

  • Media Replacement Restores Plant Capacity and Improves Flow

    Operating Issue A recycling facility that processes waste bakery products experienced significant reductions in airflow capacity, which negatively impacted their production rates. The bottleneck was a two-chamber RTO (Regenerative Thermal Oxidizer) system that took forever to start, suffered significant chamber-temperature imbalances and contained ineffective ceramic media. Factors that ...

  • Decentralized wastewater treatment using a bioelectrochemical system to produce methane and electricity

    Biological electrochemical systems (BESs) have the potential for decentralized treatment in developing countries. A 46 L, two-chamber, hydraulically partitioned microbial fuel cell (MFC) was designed to replicate low-flow scenarios leaving a composting toilet. The co-evolution of electricity and methane in this MFC was evaluated by testing two distinct waste streams: synthetic feces (Case F) ...
