  • AQUA ENVIRO - Final Report - Full ScaleTrials of Recycled Glass as Tertiary Filter Media for Wastewater Treatment. GLA36-010

    The report summarises the findings of both pilot-, and full-scale trials comparing the performance of recycled glass and sand as filter medium in tertiary filtration for suspended solids removal during wastewater treatment. The trials were undertaken at three sites: the Malton municipal wastewater treatment plant operated by Yorkshire Water; Stubbins Paper Mill, Ramsbottom, operated by Georgia ...

  • A comparative study for pathogen removal using different filter media during vermifiltration

    The present study focuses on the effect of filter media (riverbed gravel, mud balls, coal and glass balls) for the removal of pathogens during vermifiltration of domestic wastewater. This novel study was conducted for the first time on different vermifilters (VFs) with different media, and pathogen removal was extensively investigated for a period of 3 months. Results indicated that vermifilter ...

  • Sorption of per‐and polyfluoroalkyl substances (PFASs) on filter media: Implications for phase partitioning studies

    Per‐and polyfluoroalkyl substances (PFASs) including perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) are ubiquitous in the environment. Investigations into their fate and potential phase‐partitioning behaviour require separation of solid from aqueous phases via filtration. However, sorption of aqueous‐phase PFASs on filtration media may lead to underestimation of PFAS ...

  • Introducting a New Media for Fixed-Film Treatment in Decentralized Wastewater Systems

    ABSTRACTBoth naturally occurring and artificial media have been used to treat wastewater in small community settings. Systems using naturally occurring media include sand filters and peatbased biofilters. Artificial media include open cell foam, textiles, and plastics. All the above operate as fixed-film systems, in that attached growth microorganisms are encouraged to colonize and reproduce in ...

  • Solid / gas separation with fabric filters

    A myriad of filter media are utilized today for separation of particulate matter in industrial gas filtration applications. These media range from single use (deposable) to semi-permanent media and include fiber, fabric, ceramic, membrane, metal mesh, and sintered metal media. Semi-permanent media are usually cleanable, either on or off-line, and are primarily intended for long-term (up to ...

  • Footprints and Capital Costs Reduction for Onsite Wastewater Treatment Systems - a Novel Dual Media Recirculating Biofilters

     ABSTRACT The purpose of this study was to develop a dual media filter bed design for recirculating biofilters (RBFs) for achieving high level treatment to meet the strict wastewater discharge regulations. Five types of filter media were applied in the bench scale RBFs, including two single media (crushed glass or CG, geotextile or GT), and three dual media with CG and GT at different ...

  • Basic Principles of Microfiltration

    Microfiltration can be defined as the separation of particles of one size from particles of another size in the range of approximately 0.01 µm through 20 µm. The fluid may be either a liquid or a gas. Microfiltration media are available in a wide variety of materials and methods of manufacture. They can be rated either 'absolute' or 'nominal' depending upon the percentage of capture of particles ...

  • The role of solution chemistry in the stability and detachment of cohesive kaolinite particles

    The effect of solution chemistry on the behavior of kaolinite in three different situations was investigated: (1) the detachment of kaolinite from glass beads in a fluidized bed, (2) the erosion of kaolinite deposits in a laboratory flume and (3) the determination of the stress-strain rate relationship of concentrated suspensions in a rheometer. The experimental results from these three different ...

  • Upstream Particulate Removal for Rtos on Direct-Fired Osb Dryers – How much is enough?

    Abstract Since 1994 Regenerative Thermal Oxidizers (RTOs) have been applied to direct wood-fired OSB dryers for the purpose of VOC abatement. In early direct wood-fired OSB dryer applications many OSB producers felt that upstream particulate control was not necessary. However, the ash from the combustion of wood waste created a host of new operational problems for the RTO systems. This paper ...

  • Case study - Emergency equipment for the absorption of chlorine in hospitals

    Chlorine is a strong oxidant that in normal conditions and in its pure state formsdichlorine, a toxic gas with a yellow-greenish colour formed by diatomic molecules (Cl2) that are about 2.5 times heavier than air and have an unpleasant smell. Among its multiple applications and due to its powerful oxidising nature, it is widely used forwater purificationin sewage treatment plants and as ...

  • Methods of Purification

    Water Innovations Water Systems Carbon Filtration is used for several reasons. Its primary purpose is the reduction of chlorine to less than 0.1 ppm. Chorine can damage softener resins, reverse osmosis membranes, and mixed bed deionization resins. Activated carbon will also help control tastes and odors, provide organic and hazardous organic chemical ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...
