the down-flow hanging sponge (dhs) reactor, which was developed for post-treatment of effluent from up-flow anaerobic sludge blanket (uasb) process treating sewage, uses polyurethane sponge as media to retain biomass. wastewater is trickled from the top of the reactor and purified by microorganisms retained both inside and outside of the sponge media as the wastewater flows vertically down thro...

a lab-scale cross flow membrane bioreactor (cf-mbr) was operated to determine the biokinetic coefficients under mlss concentrations of 5000 and 3000 mg/l. the investigation showed that the yield (y), the endogenous decay coefficient (kd), the maximum specific growth rate (μm) and the saturation constant (ks) were 0.276 mg/mg, 0.07 /day, 0.653 /day, and 396.62 mg cod/l respectively for mlss 500...

transport of pathogenic bacteria has been recently considered a major source surface and subsurface water contaminations. soil could affect transport or filtering of bacteria depending on its physical and chemical properties. calcium carbonate and calcium sulfate are two important minerals of arid and semi-arid soils that their effect on bacteria transport has not been investigated, yet. in thi...

Blood conservation methods are commonly practiced throughout most hospitals that conduct cardiothoracic surgery. In an effort to reduce patients' exposure to homologous blood products and due to cost effectiveness of blood conservation techniques, this present study combines autotransfusion of the remaining blood in the extracorporeal circuit and ultrafiltration of the plasma effluent, and desc...

A challenge for capillary LC (cLC) is fraction collection and the manipulation of fractions from microscale columns. An emerging approach is the use of segmented flow or droplet technology to perform such tasks. In this work, a fraction collection and postcolumn reaction system based on segmented flow was developed for the gradient cLC of proteins. In the system, column effluent and immiscible ...

Improving the hydraulic performance of waste stabilization ponds (WSPs) is an important management strategy to not only ensure protection of public health and the environment, but also to maximize the potential reuse of valuable resources found in the treated effluent. To reuse effluent from WSPs, a better understanding of the factors that impact the hydraulic performance of the system is neede...

denitrification of high- nitrate high- salinity wastewater is difficult due to plasmolysis and inactivation of denitrifiers at high salinity conditions. in this study, the effects of salinity and empty bed contact time (ebct) on simultaneous heterotrophic and sulfur based autotrophic denitrification of synthetic wastewater were evaluated in an up flow packed bed reactor .the reactor was filled ...
