  • Advantages and basic facts for the use of Lenzing PROFILEN based filter media

    Normal PTFE filter bags have a very good chemical resistance but on the other hand they do not have a high dust separation efficiency. Lenzing PROFILEN® is a compromise between a high efficiency and a high flow rate after cleaning of gases with all the positive aspects of normal PTFE bags. Basics To acquire a better feeling and understanding for the advantages of Lenzing PROFILEN® it is necessary ...

  • Effects of physical disturbances on media and performance of household-scale slow sand (BioSand) filters

    Point-of-use (POU) water treatment provides households in rural and remote communities with a means of obtaining greater control over their water quality and its effects on human health. One of the most prevalent POU interventions, the BioSand filter (BSF), is a household-scale, intermittently operated slow sand filter used by over 300,000 households. The sand and gravel media within BSFs can be ...

  • Performance of plastic- and sponge-based trickling filters treating effluents from an UASB reactor

    The paper compares the performance of two trickling filters (TFs) filled with plastic- or sponge-based packing media treating the effluent from an upflow anaerobic sludge blanket (UASB) reactor. The UASB reactor was operated with an organic loading rate (OLR) of 1.2 kgCOD m−3 d−1, and the OLR applied to the TFs was 0.30–0.65 kgCOD m−3 ...

  • 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 ...

  • Unmixing Water From Waste: The imporance of filters, cartridges and housings as a function of manufacturing

    In manufacturing, water and water-based solutions are regularly filtered for various purposes and outcomes – including for cleaning, cooling, and movement. The filtering process is crucial to quality, performance, and cost savings. With the wrong filter in place, pumps can be destroyed, liquid being filtered can become “unusable” for the intended purpose, cleaning solvents can ...

  • Modeling Fixed Film Processes: Practical Considerations and Current Limitations from a Consulting Viewpoint

    ABSTRACT Fixed film technologies such as integrated fixed film activated sludge (IFAS), moving bed bioreactors (MBBR), biological aerated filters (BAF) and denitrification filters are gaining popularity in the United States for a number of reasons. As a result, there is a renewed desire to model these processes, particularly for consulting engineers interested in designing these processes. ...

  • Hepa this Hepa that, is there such thing as a true Hepa vacuum?

    We all see it, the big Hepa sticker on the side so we automatically believe the vacuum must be a Hepa rated vacuum, right? - Sorry the chances are the Vacuum would never pass a Certified D.O.P test. Just because a vacuum has a Hepa filter doesn't make it a Hepa vacuum, many factors have to be taken into account such as: The Hepa Filter needs to be sized according to the airflow ...
