This study describes the temporal and spatial variability of bacterial communities within a combined sewer system in England. Sampling was conducted over 9 months in a sewer system with intensive monitoring of hydraulic conditions. The bacterial communities were characterized by 16S rRNA gene-targeted terminal restriction fragment length polymorphism analysis. These data were related to the hyd...
Fused Deposition Modeling (FDM) is a kind of Rapid prototyping (RP) technique, which allows direct transformation of CAD files into physical models. This paper attempts to identify and study the influence of electroplating layer thickness on the mechanical strength of Acrylonitrile butadiene styrene (ABS) samples developed from the FDM process. The study is conducted on the tensile test samples...
The use of lithography and electroplating to fabricate variable-reluctance, nearly planar, integrated minimotors with 6-mm-diameter rotors on silicon wafers is described. The motors consist of six electroplated Permalloy@ horseshoe-shaped cores that surround the rotor. Copper coils are formed around each core. The Permalloy and copper electroplating baths, electroplating seed layers, and throug...
Activated carbon has been prepared from Citrus limettioides peel (CLPC); a novel waste material by chemical modification with sulphuric acid followed by bicarbonate treatment applied for the adsorption of Ni(II) from aqueous solutions. Batch experiments have been carried out to study the effect of various parameters such as contact time, pH and adsorbent dosage on various Ni(II) concentrations ...
A new membrane process is described that can be used to recoverplating chemicals from electroplating rinse waters. The process, called coupled transport, is based on liquid membranes that are comprised of a thin, polymeric microporous support containing a metal-ion complexing agent within the pores. Metal ions present in the rinse solutions are transported across these membranes and can be conc...
Microorganisms play a significant role in bioremediation of heavy metal contaminated soil and wastewater. In this study, heavy metal resistant fungi and bacteria were isolated from the soil samples of an electroplating industry, and the bioaccumulations of Cr(VI) and Ni(II) by these isolates were characterized to evaluate their applicability for heavy metal removal from industrial wastewaters. ...
The objectives of the research were to evaluate a magnetite-based adsorption process as an alternative treatment technique for removing metals from industrial wastewaters. A composite adsorbent was prepared b precipitating sorption, magnetic separation, and desorption process to recover Cr or Zn from solution The process was effective, but performance decreased when the adsorbent was recycled. ...
