This study explored the combined effects of photocatalysis with ceramic membrane filtration for the removal of humic acid in the presence of salt; to simulate saline wastewater conditions. The effects of operating parameters, such as salinity and TiO₂ concentration on permeate fluxes, total organic carbon (TOC), and UV absorbance removal, were investigated. The interaction between the humic aci...

We present the development, implementation and measurement of a 3D-deployed RF front-end System-onPackage (SOP) topology in a standard low-loss multi-layer ceramic (LTCC) technology. A compact 14 GHz GaAs MESFETbased satellite transmitter integrated with a low-loss embedded filter for outdoor units were built on a 400 × 310 × 35.2 mil3 943AT tapes. The LTCC stripline filter exhibits a measured ...

Low Temperature Co-fired Ceramic (LTCC) technology is a multi-layer ceramic process that can be used to fabricate low cost, high performance RF and microwave components. It is an extremely versatile technology that can be used to realise a wide range of components from simple passive filter structures and packages to complex sub-system assemblies containing discrete SMT (Surface Mount Technolog...

Gas film mass transfer coefficients (kGat , kGaw) and liquid film mass transfer coefficients (kLaw) for packing materials used in biofilters and biotrickling filters for air pollution control were determined experimentally. Lava rock, polyurethane foam cube (PUF), Pall ring, porous ceramic beads, porous ceramic Raschig rings and compost–woodchips mixtures were investigated. The experiments were...

This study presents the operation of a biotrickling filter when treating a monochlorobenzene (MCB) contaminated gaseous emission. Treatment dynamics were characterised by exposing the reactor to various MCB Organic Loads (OL). The use of different growth support materials, namely limestone, sand, ceramic and PVC pall-rings, was investigated. Limestone led to dogging of the reactor due to the ac...

Introduction Coal gasification produces residual particles of coal char, coal ash, and sorbent that are suspended in the fuel gas stream exiting the gasifier. In most cases, these particles (referred to, hereafter, simply as char) must be removed from the stream prior to sending the gas to a turbine, fuel cell, or other downstream device. Currently, the most common approach to cleaning the gas ...
