Ion–conducting ceramic membranes, such as mixed oxygen ionic and electronic conducting (MIEC) membranes proton–electron (MPEC) have the potential for absolute selectivity specific gases at high temperatures. By utilizing these in membrane reactors, it is possible to combine reaction separation processes into one unit, leading a reduction by–product formation enabling use of thermal effects achi...

The increasing use of motor vehicles, the greater amount engine oil consumption. Engine cannot be used continuously due to frictional force on engine, so is purified. Unused can pollute environment because it categorized as B3 waste. Used has a higher metal content than new oil. reduction in done by using filtration column containing zeolite and activated carbon with height 20 cm from each medi...

An intermittent aerator was newly developed to reduce energy costs in a flat-sheet ceramic membrane bioreactor (MBR) for industrial wastewater treatment. Large air bubbles were supplied over short time interval by the improved technology at bottom of membrane. Performance tests carried out pilot system with two cassettes immersed tank 1-MGD demonstration plant Jurong Water Reclamation Plant (JW...

A ceramic membrane modified with corncob activated carbon (CMCC) has been successfully prepared and used to reduce the concentration of remazol red in batik wastewater. This research aims study effect (CC) on porosity its ability dye The variation % CC mass clay was 0%, 5%, 10%, 15%, 20%, 25%. Characterization includes ash content characterization CMCC test, morphological analysis, elemental di...

The recovery of high-quality, valuable end products from cheese whey is a very important industrial process. The aim of this study is to improve the recovered protein content of concentrate stream in cheese whey. The experiments were conducted by using ceramic ultrafiltration (UF) membrane followed by diafiltration (DF) process with a 15kDa molecular weight cut-off (MWCO). The volume concentrat...

With the use of silicon micromachining an inorganic membrane sieve for microfiltration is constructed, having a siliconnitride membrane layer with thickness typically 1 pm and perforations typically between 0.5 pm and 10 pm in diameter. As a support a -silicon wafer with openings of loo0 pm in diameter is used. The thin siliconnitride layer is deposited on an initial dense support by means...

DESCRIPTION In wastewater treatment processes, aeration introduces air into a liquid, providing an aerobic environment for microbial degradation of organic matter. The purpose of aeration is twofold: 1) to supply the required oxygen to the metabolizing microorganisms and 2) to provide mixing so that the microorganisms come into intimate contact with the dissolved and suspended organic matter. T...
