this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...

chemical wastewater treatment is one of the attracting and common methods for wastewater treatment among the currently employed chemical unit processes. the use of coagulant-flocculant compound is one of the efficient methods for separating of paint and recovery of water. in this research, it was introduced and the effect of ph on removal of solid content from solution was studied experimentall...

the efficiency of existing municipal wastewater treatment plants has been affected by the increase of incoming organic load caused by the expansions in developing countries. in the present investigation, the effect of chemically enhanced primary treatment (cept) process was studied on the enhancement efficiency of a municipal wastewater treatment plant in tehran, iran. jar test results showed a...

The bioefficacy of a commercial formulation of temephos, Creek against Aedes aegypti larvae was studied in the laboratory. Earthen jars were filled with 10 L tap water each. One g of temephos (Creek) sand granule formulation was added into each earthen jar as recommended by the manufacturer. The final test concentration of Creek was 1 mg a.i./L. One earthen jar was filled with 10 L tap water an...

There are several typographical errors in this Article. In the legend of Figure 7, ‘‘(Open triangles with dashed line)’’ should read, ‘‘(Open triangles with solid line)’’ and, ‘‘(Open circles with solid line)’’ should read, ‘‘(Open circles with dashed line)’’. In the Results, JAR 41 elicits human complement-mediated bactericidal activity with second anti-fHbp mAbs subsection, ‘‘(for example, JA...

The consumption of jar water has been increasing consistently in these days. To improve such water quality and supply, information is needed to assess water contamination in a variety of community, including those that rely primarily on unimproved distributed sources of drinking water. This study was done to assess the public perception on drinking jar water and assessment of drinking jar water...

the studies report the synthesis of novel graft copolymer of oatmeal. polymethyl methacrylate grafting was carried out on oatmeal backbone via ‘microwave assisted’ approach. the graft copolymers were optimized by varying monomer and can concentration. the synthesized graft copolymers were characterized by intrinsic viscosity, ftir, tga, sem, elemental analysis, number average molecular weight a...

are placed at the bottom of the jar, one of the usual oxygen indicators (for example, alkali^6' glucose-methylene-blue mixture) placed aloflj? with the cultures, and the jar sealed. After jj to 12 hours, according to the size of the jar an" the amount and quality of iron filings, the colour of the indicator is discharged and co1*^ plete anaerobiosis obtained. Approximately " grammes of iron fil...
