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 ...

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 ...

Long-term studies on hybrid ceramic microfiltration for treatment of surface water containing high dissolved organic matter

by IWA Publishing  (Apr. 14, 2014)

This long-term pilot-scale study on the performance of ceramic microfiltration (CMF) was conducted at the Bangkhen water treatment plant (BWTP), with the raw water from Chaophraya River, Thailand. Raw water turbidity and dissolved organic carbon (DOC) were varied in the ranges of 20–210 NTU and 3.0–8.5 mg/L respectively. The hybrid ...

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 ...

The Use of Ceramic Membranes in the Fruit-Juice Industry to produce intensely coloured, brilliant and stable juices

by atech innovations gmbh  (Aug. 1, 2013)

1 Introduction The production of high quality juices or juice concentrates from coloured fruits is a complex task with a multiplicity of parameters which have an effect on the final quality. atech innovations gmbh, a German manufacturer of ceramic membranes, and the Swiss engineering company Unipektin AG have developed a filtration process by ...

Removal of DOM and THM formation potential of tropical surface water by ceramic microfiltration

by IWA Publishing  (Oct. 19, 2012)

Dissolved organic matter (DOM) and trihalomethane formation potential (THMFP) removal by ceramic microfiltration (CMF) under different operating conditions was investigated and compared with the performance of a conventional water treatment plant at Bangkhen, Thailand. The tropical surface raw water for all the experiments was taken from ...

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 ...

Bacteria removal effectiveness of ceramic pot filters not applied with colloidal silver

by IWA Publishing  (Dec. 1, 2011)

In many developing countries such as Guatemala, access to safe drinking water is very limited. Many sources of water that are available are contaminated with bacteria, particularly Escherichia coli and other coliform bacteria. In order to provide a means of obtaining safe drinking water in developing countries, various methods of treating water at ...

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), ...

Virus removal efficiency of Cambodian ceramic pot water purifiers

by IWA Publishing  (Jun. 1, 2011)

Virus removal efficiency is described for three types of silver-impregnated, ceramic water filters (CWFs) produced in Cambodia. The tests were completed using freshly scrubbed filters and de-ionized (DI) water as an evaluation of the removal efficiency of the virus in isolation with no other interacting water quality variables. Removal ...
