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 ...

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 ...

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 ...

Why Current Water Treatment Technology Can`t Solve The Global Water Crisis

by Biolargo, Inc.  (Aug. 14, 2014)

Summary GE, Veolia, Dow and American Water Works are selling billions in water treatment technology. All their water treatment technologies work or they wouldn't be selling. In spite of effective water treatment technologies, the global water crisis persists. The problem is the high cost of current ...

Clarification of rough beer in brewery industry case study

by RVF-filtration  (May 9, 2014)

Standard filtration uses diatomaceous earth (Kieselguhr) into filter-press and consists in the retention of solid particles (yeast cells, macrocolloids, suspended matter) and solutes responsible for haze. After use the disposal of Kieselguhr (after filtration) are a major difficulty due to their polluting effect. From the health perspective, the ...

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 ...

YEAR: 2003 COUNTRY: ITALY N° and MACHINERY MODEL EMPLOYED: 1  JETFILTER RH 1000.70 Diemme® Filtration The customer is a company that produces ceramic pastes, requiring the dewatering of ceramic barbotine, a colloidal material which is difficult to dewater. It already had a filter press that did not have the ...

Comparing environmental impacts of tertiary wastewater treatment technologies for advanced phosphorus removal and disinfection with life cycle assessment

by IWA Publishing  (Apr. 24, 2014)

Different technologies for tertiary wastewater treatment are compared in their environmental impacts with life cycle assessment (LCA). Targeting very low phosphorus concentration (50–120 μg/L) and seasonal disinfection of wastewater treatment plant (WWTP) secondary effluent, this LCA compares high-rate sedimentation, microsieve, ...

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 ...

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 ...
