  • Ceramic membranes for water treatment

    Ceramic membranes, different in pore size and membrane material, were applied to remove particulate and dissolved matter from different spent filter backwash water types as well as from dam water. The study was conducted in pilot scale under conditions typical for waterworks at a dam water treatment plant. A comparison of different ceramic membranes implied that total membrane resistance was more ...

  • Ceramic Membranes in Sludge Thickening Applications

    The Aerobic Digestion group has recently been conducting pilot testing of silicon carbide ceramic membranes manufactured by the Danish company Cembrane A/S.  This promising technology shows a great ability to filter water even in the challenging high solids environment of sludge thickening.  The results of the pilot testing have led the aerobic digestion group to utilize ...

  • Evaluation of an emerging water treatment technology: ceramic membranes

    Historically, low-pressure membranes (microfiltration (MF) and ultrafiltration (UF)) used in potable water treatment are made of polymers (polysulfone (PS), polypropylene (PP), polyethersulfone (PES), polyvinylidene fluoride (PVDF) etc). Recently, membranes made of ceramic materials (aluminium oxide) have been developed by MetaWater (Japan), Kubota (Japan) and others and is being marketed in the ...

  • Assessment of a membrane drinking water filter in an emergency setting

    The performance and acceptability of the NeroxTM membrane drinking water filter were evaluated among an internally displaced population in Pakistan. The membrane filter and a control ceramic candle filter were distributed to over 3,000 households. Following a 6-month period, 230 households were visited and filter performance and use were assessed. Only 6% of the visited households still ...

  • Chemical and microstructural analyses for heavy metals removal from water media by ceramic membrane filtration

    This study aims to investigate the ability of low cost ceramic membrane filtration in removing three common heavy metals namely; Pb2+, Cu2+, and Cd2+ from water media. The work includes manufacturing ceramic membranes with dimensions of 15 by 15 cm and 2 cm thickness. The membranes were made from low cost materials of local clay mixed with different sawdust percentages of ...

  • Working on a Love/Hate Relationship with the Surface Chemistry of Membrane Filters

    Water, oils, and solvents sometimes need to be filtered. But when you see filters labeled as hydrophilic, hydrophobic, and now oleophobic; what does all this mean?  Sterlitech currently offers membrane disc and sheet filters in 10 different polymer types and 4 inorganic filters. 2 of the polymer types are subdivided into 4 subgroups based on surface ...

  • City Water International explains The Basics of Water Filtration

    The Basics of Water Filtration Most of us know that filtered water is healthier than tap water because of its purity, but how does water filtration work? The basic principle is that filtered water has passed through a filter which removes contaminants through one of several methods, depending on the type of filter. Most water purification systems work in one of three ways ­ by running water ...

  • 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 ...

  • Microfiltration vs Ultrafiltration Processes: What is the Difference?

    Microfiltration (MF) and ultrafiltration (UF) are both processes by which a contaminated liquid is passed through a semipermeable membrane that removes solids too large to fit through the membrane’s pore size, yielding a purified liquid stream. To what degree the stream is purified depends on the contaminants present and the pore size of the membrane. MF and UF are generally ...

  • Ideal treatment of laundry wastewater with ultrafiltration installations

    Treatment of very dirty work clothing also produces heavily polluted, oily/greasy wastewater. It is the aim of laundry wastewater treatment to reduce fresh water consumption and to minimise the volume of residuals. At the same time, adherence to the limit values according to appendix 55 of the General provisions on hydrocarbon, heavy metal and AOX contamination in wastewater must be guaranteed. ...
