  • The Dangers of Hydrogen Sulfide and Filtration with Activated Carbon

    Hydrogen sulfide (H2S) is a poisonous, highly flammable, colorless gas that is associated with a ‘rotten egg’ odor. As stated by cchealth.org, “hydrogen sulfide is created naturally by decaying organic matter and is released from sewage sludge, liquid manure, and sulfur hot springs.” It also is a by-product from industrial processes such as natural gas processing, ...

  • Effect of active control of electric potential of filter medium on depth filtration

    The effect of active control of electric potential of filter medium on depth filtration was explored experimentally. Activated carbon particles were selected as the conductive filter medium. The filter medium potential was controlled with an external DC power supply. Kaolin particles were used as the model suspended solid. The activated carbon and kaolin had negative zeta potential around neutral ...

  • Evaluation of Tire Derived Rubber Particles for Biofiltration Media

    ABSTRACTCurrently, on average, one tire is discarded in the U.S. for every man woman and child every year. While the reuse market for used tires has increased over the years to approximately 75%, there are still an estimated 2-3 billion used tires stockpiled in the U.S. Finding economical and sustainable end uses for this tire material is an ongoing challenge to environmental engineers and ...

  • Developments in string wound filter cartridges

    String wound filter cartridges are the most commonly used filtration media for reducing contamination in water and other liquids. Filtration applications include reverse osmosis and water softening prefiltration, boiler feed water for steam generation, cooling towers and heat exchangers, bottled water, edible oils, oil and gas production, process water for textiles, electroplating and anodizing ...

  • Bio-augmentation of fixed film filters

    Once regarded as the main process option for the waste water treatment for small communities, circular biological filters, so common on the outskirts of towns for many years, provided a reliable low cost and low profile method of treating household waste water. Quiet and robust, their simple engineering and structural design could be easily maintained by a daily visit from an operator, who, on ...

  • Treatment of petrochemical secondary effluent by an up-flow biological aerated filter (BAF)

    In this study, petrochemical secondary effluent was treated by a 55 cm diameter pilot-scale biological aerated filter (BAF) with a media depth of 220 cm. Volcanic rock grains were filled as the BAF media. Median removal efficiency of chemical oxygen demand (COD) and ammonia nitrogen (NH3-N) was 29.35 and 57.98%, respectively. Moreover, the removal profile of the COD, NH3-N, total ...

  • Rich microbial communities inhabit water treatment biofilters and are differentially affected by filter type and sampling depth

    Factors affecting microbial diversity (richness) and community structure in biofilter columns were investigated. At a pilot filtration plant, granular activated carbon (GAC), anthracite and sand-based filters were used to treat stormwater from an urban catchment. After 12 weeks operation, sand media filters clogged (hydraulic conductivity declining by 90%) and all filters were destructively ...

  • Biofiltration as pre-treatment to water harvesting and recycling

    This paper presents the results of the long term biofilter experiments conducted with raw stormwater collected from a canal at Carlton, in Sydney. Anthracite and granular activated carbon (GAC) were used as a single filter media in biofilter columns. Media heights of 75 and 40 cm were used. The filter columns were operated at filtration velocities of 0.12 and 0.25 m/h. The removal efficiency for ...
