Ceramic waste is most commonly produce from ceramic industry, this waste is in the form of pest and hard form, pest waste is known as the filter waste or slurry waste, which is produced at the end of polishing and finishing of ceramic tiles. The paper discuss that ceramic slurry waste powder is replaced by cement in concrete. Concrete grade M25 was made by replacing by 0% to 30% of Ordinary Por...

This paper describes current and on-going work in adapting Z-Corp 3D printers to operate with low-cost ceramic materials. The components produced with these clay-based ceramic powders can be fired to produce strong, complex and lightweight ceramic parts. The final material properties, including the porosity of the parts, can be controlled through the part design and, potentially, through additi...

This paper presents a novel third-order cross-coupled rectangular cavity filter by using standard low-temperature cofired ceramic (LTCC) technology, in which the multilayer substrate integrated waveguide (SIW) is implemented. Particularly, the desired filter has a single finite frequency attenuation pole at j4.0 with asymmetrical frequency selectivity. An experimental band pass filter (BPF) has...

SIMULATION OF DUST CAKE BUILD-UP ON THE FILTER MEDIUM This section describes a physical model for cake and pressure build-up on candle filters. The model was aimed at investigating filtration operation and reverse pulse cleaning of the filter. It is useful to calculate the filter cake thickness and pressure drop along the filter candle. Figure 1 shows the schematic diagram of filter cake build-...

A technique of computing the pressure drop and deposition rate evolution during soot loading and the 3D distribution of deposited soot particles for micro-structured ceramic filter media is presented. Methods developed at Fraunhofer ITWM for generating 3D computer models representing the microstructure of the filter material and for computing soot particle deposition in the microstructure model...

This paper aims to discuss the filter structures which constitutes a planar inductor, capacitors using microstrip lines and make it tunable taking the advantage of LTCC multilayer design. Investigations of passive multilayer filter structure using low-temperature co-fired ceramic (LTCC) for microwave and radio frequency application is studied. A roadmap for performance and process parameters to...

As part of its response to flooding in the Dominican Republic in 2003, Oxfam GB distributed ceramic “candle” water filters to householders in 7 affected communities. In a randomized, controlled trial conducted among 80 householders in one community during the six-month design life of the ceramic filter elements, faecal water contamination was consistently lower among intervention households tha...
