The aim of this study was to search for a specific antibody pattern in sera from patients suffering from Helicobacter pylori-related gastric adenocarcinoma (GAC). The serological response of 22 patients suffering from GAC, 31 patients with gastroduodenal ulcer, and 39 asymptomatic subjects was analyzed using immunoblotting performed with three H. pylori strains: strain ATCC 43579; strain B110, ...

Optimizing the characteristics of granular activated carbon (GAC) can improve performance biologically (BAC) filters, and iodine value has always been principal index for GAC selection. However, in this study, among three types treating same humic acid-contaminated water, one had an 35% lower than other two, but dissolved organic removal efficiency its BAC was less 5% away from others. Iodine f...

Reclamation and reuse of wastewater are increasingly viewed as a pragmatic tool for water conservation. Greywater, which includes from baths, washing machines, dishwashers, kitchen sinks, is dilute stream, making it an attractive stream extraction non-potable water. However, most previous studies primarily focused on passively aerated biological physicochemical treatment processes greywater tre...

A demonstration plant consisted of granular activated carbon (GAC) and ozone/GAC process was operated using filtered water of a conventional water treatment plant as influent to study feasibility of introducing advanced water treatment. Natural organic matter (NOM) from process waters at the demonstration plant was isolated into hydrophobic and hydrophilic fractions by physicochemical fractiona...

efore the 1970s, research into the nature of natural organic matter (NOM) in drinking water and into methods for its removal was driven primarily by the desire to remove color from public water supplies. Since then, several other problems associated with NOM have been identified, including its demand for coagulants and disinfectants, its potential to transport metals and hydrophobic organic che...

Dual membrane hybrid systems generally produce reclaimed water for non-potable uses by blending microfiltered biologically treated sewage effluent (BTSE) and reverse osmosis (RO) permeate. This is found to contain a significant amount of micro-pollutants, which possibly cause toxicity effects aquatic organisms plants when exposed it. Therefore, removing such pollutants from the before reaching ...

With increasing awareness of reduction of energy and CO2 footprint, more waste is considered recyclable for generating value-added products. Here we reported the negatively-valued iron mud, a waste from groundwater treatment plant, was successfully converted into magnetic adsorbent. Comparing with the conventional calcination method under the high temperature and pressure, the synthesis of the ...

We explore the use of Granular Activated Carbon (GAC) as a mitigation technique for the treatment of drinking water that was artificially enriched with Rn-222 in laboratory by placing a radium rich granite stone (pitchblende) in a closed container filled with tap water for several days in order to allow Rn-222 concentration to approach its highest possible level. Granular Activated Carbon (GAC)...

Treatment of wastewater from a tannery in Greater Ho Chi Minh City (Vietnam) was investigated on a pilot scale. After pre-treatment by the tannery that included batch-coagulation and sedimentation, the wastewater was treated by dissolved air flotation, a membrane bioreactor (MBR) and granular activated carbon (GAC) for polishing the MBR effluent. The average removal efficiency for organic subst...
