Filtration is the most cost effective method to purify aluminum. In this paper, filtration experiments have been carried out using both AlF3 slurry coated, and uncoated Al2O3 ceramic foam filter (CFF) to study the removal of both nonmetallic inclusions and impurity elements. The results showed that the 30 ppi CFF removed up to 85% inclusions from aluminum. The contributing mechanisms for the re...

A catalyst with a high activity in tar conversion, impregnated on the ceramic hot gas filter material was developed. The aim of experiments to estimate light-off temperature catalytic elements for naphthalene (tar model compounds) conversion and long-term stability at 700 °C. Configuration optimized through improvements coking resistance stability. composition morphology parameters were conside...

The spread of Diseases like Cholera and Diarrhea, which leads to loss lives in developing countries is commonly caused by use contaminated water. In this study ceramic pot filters for rural area water purification were developed. clay sample was tested physical properties the mixtures sawdust made seven (7) proportions 75/25, 70/30, 65/35, 60/40, 55/45, 50/50, 45/55. soil tests conducted on dif...

Abstract Background Approximately 69% of population in Tanzania lacks better sanitation, while 45.6% access to clean and safe water. To leverage this shortage, several technologies have been used for purifying water from various sources; however, there is still persistence waterborne diseases. Main body This article reviewed the efficiency common filters removing contaminants such as Escherichi...

This paper proposes a new Gabor filter-based generative approach to texture abnormality detection, called Gabor Composition or GC. The GC algorithm, a combination of Gabor filtering and co-occurrence analysis, employs a Gabor filter bank to generate a multi-scale and multidirectional feature map of the test image. The feature map is then fed to a co-occurrence based feature extraction module, w...

The out-band transmission zeros of the multilayer low-temperature co-fired ceramic bandpass filter are studied in this paper. The design target of this filter, with the passband between 2.3–2.65 GHz (the true application is 2.4–2.483 GHz), is to reject the local oscillator and image signals and, in the mean time, to suppress the harmonic frequency. This filter is a modified three-pole combline ...

The need for drinking water with affordable access is increasing nowadays. poor quality problems can be solved by several treatment methods, i.e. ceramic filter (CF) and pervious concrete (PCF). Those two mentioned technologies work based on the pores that exist within filter. This study aimed to review (1) influence of material composition CF PCF hydraulic characteristics (porosity, permeabili...
