Houshold Water Treatment in Developing Countries: Ceramic Filtration

by IWA Publishing  (Mar. 8, 2012)

Household water treatment and safe storage (HWTS) interventions are proven to improve water quality and reduce diarrheal disease incidence in developing countries.  Five of these proven HWTS options – chlorination, solar disinfection, ceramic filtration, slow sand filtration, and flocculation/disinfection – are widely implemented ...

Fabrication of catalytic ceramic membranes for water filtration

by IWA Publishing  (Mar. 1, 2010)

The paper describes the use of the layer-by-layer technique to coat ceramic membranes with iron and manganese oxide nanoparticles. The coatings are thin ...

Filtration by Means of Ceramic Membranes - Practical Examples from the Chemical and Food Industries

by atech innovations gmbh  (Aug. 1, 2013)

Traditionally, ceramic membranes have been used in waste water engineering. Meanwhile, they are applied in all areas where media need to be filtered, such as in recycling processes in the chemical industry, for cell separation in biotechnology or for fruit-juice filtration in the food industry. 1 Introduction Ceramic membranes based on aluminum ...

Ceramic membranes for water treatment

by IWA Publishing  (Jan. 1, 1900)

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 ...

Ceramic membranes with higher abrasion resistance

by atech innovations gmbh  (Dec. 26, 2013)

High flux rates, combined with a very high chemical and thermal resistance and the resulting operational reliability - these are the reasons why users worldwide opt for ceramic membranes. Up to now, the only parameter where ceramic membranes performed well but not excellent was abrasion resistance. Therefore, filtering of abrasive matter ...

Dye wastewater treatment by using ceramic membrane bioreactor

by Inderscience Publishers  (Jul. 20, 2009)

Performance of a Micro-filtration Membrane Bioreactor (MMBR) for treatment of dye wastewater was investigated. The experimental results indicated that the removal efficiency for COD, TOC and colour was 85%, 85-90% and 70%, respectively, the effluent COD was below 70 mgl−1 on average. Gel layer resistance of COD was 10%. Particle size distribution ...

Evaluation of an emerging water treatment technology: ceramic membranes

by IWA Publishing  (Dec. 1, 2010)

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), ...

Case Study - Organic Particulate Filtration

by Anguil Environmental Systems, Inc.  (Jan. 2, 2008)

Overview A food products company that mixes various types of waxes and other components to make the base for chewing gums was faced with the issue of cleaning up a slightly odorous, visible emission being exhausted from two of their process lines. The components of the emission were hot particles of chewing gum and some volatile organic compounds ...

Wastewater treatment using bioreactor with dual functional ceramic membrane

by Inderscience Publishers  (Jul. 20, 2009)

A novel bioreactor including a group of dual functional ceramic membranes was developed and used for wastewater treatment. The ceramic membranes could be used for both aeration and filtration alternately, so fouling to ceramic membrane would be palliated effectively as its dual functions. For 100 days operation, COD removal ratio was 88∼97% for ...

Ceramic membrane ultrafiltration of natural surface water with ultrasound enhanced backwashing

by IWA Publishing  (Mar. 1, 2010)

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 ...
