• MABR system was tested at low C:N ratio (< 1) for space-based wastewater. HRT, Recycle Ratio & intramembrane partial pressure of O 2 influences N removal. achieved maximum TN removal efficiency 36.5 %. High liquid velocity increases the diffusion resulting in denitrification. A membrane-aerated biofilm reactor (MABR) designed treatment a source-separated urine wastewater formulated to mimic c...

This investigation aimed to compare the disinfection by-product formation potentials (DBPFPs) of three UK surface waters (1 upland reservoir and 2 lowland rivers) with differing characteristics treated by (a) a full scale conventional process and (b) pilot scale processes using a novel suspended ion exchange (SIX) process and inline coagulation (ILCA) followed by ceramic membrane filtration (CM...

Wastewater from a pharmaceutical formulation facility (TevaKS, Israel) was treated with a biological activated-sludge system followed by ozonation. The goal was to reduce the concentrations of the drugs carbamazepine (CBZ) and venlafaxine (VLX) before discharging the wastewater to the municipal wastewater treatment plant (WWTP). Both drugs were detected at extremely high concentrations in TevaK...

Winter cooling and mixing brings nutrients (nitrate and phosphate) to the surface waters over large parts of the northern Arabian Sea, but the rates of primary production as well as carbon export from the euphotic zone are not especially high during the northeast monsoon. A multi-disciplinary time-series study conducted over a period of 13 d around 21° N, 64° E during the northeast monsoon of 1...

Comparison of two commonly used techniques for molecular weight determination of natural organics, ultrafiltration (UF) fractionation and high-performance size exclusion chromatography (SEC), shows that neither technique gives absolute measures of molecular weight. Investigations of International Humic Substances Society standard humic and fulvic acids as well as natural organic matter concentr...

This White Paper points out the most significant issues which can be encountered during DO-254 compliant verification process for FPGA designs. It proposes the methods of saving development time during the functional verification process, reusing the work done during RTL simulation and performing the in-hardware at-speed testing in target FPGA devices assuring at the same time a high visibility...
