  • Characteristics of ozone decomposition inside ceramic membrane pores as nano-reactors

    The characteristics of ozone decomposition inside the nano-pores of ceramic membranes were identified according to nano-reactor configuration. Three types of ceramic membranes with a pore size of 50 nm were tested with compositions of Al2O3, MnO2/Al2O3 (4%) and CeO2/Al2O3 (4%) respectively. The results ...

  • The removal of disinfection by-product precursors from water with ceramic membranes

    The main objective of this work was to investigate the effectiveness of ceramic ultrafiltration (UF) membranes with different pore sizes in removing natural organic matter (NOM) from model solutions and drinking water sources. A lab-scale, cross-flow ceramic membrane test unit was used in all experiments. Two different single-channel tubular ceramic membrane modules were tested with average pore ...

  • 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 ...

  • Practical challenge testing of a ceramic membrane module in a full-scale mobile drinking water treatment system

    Challenge testing was carried out of full-scale prefiltration and ceramic ultrafiltration (UF) modules in a mobile drinking water treatment system. Three consecutive indirect integrity tests were performed using naturally contaminated public drinking water, stocking with wastewater as well as addition of powdered activated carbon. Besides checking the removal efficiency and integrity of the ...

  • Ceramic membrane ultrafiltration of natural surface water with ultrasound enhanced backwashing

    Ultrafiltration membrane cleaning with ultrasound enhanced backwashing was investigated with two ceramic membrane systems in parallel. One of them was subjected to ultrasound during backwashing, the other acted as a reference system. The feed water was directly taken from a creek with a sedimentation process as only pre-treatment. The cleaning performance was improved with ultrasound but after 3 ...

  • 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 ...
