Cake porosity analysis using 1D–3D fractal dimensions in coagulation–microfiltration of NOM

by IWA Publishing  (Mar. 16, 2015)

Fouling during coagulation–ceramic microfiltration of natural organic matter was investigated. Two process configurations (inline coagulation (IC) and tank coagulation (TC)) and two process conditions (types of coagulants–aluminum-based PAX and iron-based PIX–and G-values) were studied. The rate of irreversible fouling ...

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 ...

From Pilot Studies to Full Scale Plant

by EnviroChemie GmbH Technology for Water  (Jan. 16, 2015)

Natural gas is widely used as a primary energy source and is one of the most efficient fuel source. For this reason, more and more gas is utilized exceeding existent production facilities. Oil and gas companies therefore expand there measures and step behind borders finding and exploit new resources. One area of major interest is the Barents Sea, ...

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 ...

Ideal treatment of laundry wastewater with ultrafiltration installations

by EnviroChemie GmbH Technology for Water  (Jan. 16, 2015)

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 ...

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 ...
