iran, for it's socio-economic development is faced with limitations, because of growing population, economic drawbacks and shortcomings in resources. therefore, country planning should be based on considering the limitations. at present, water treatment industry in iran is regarded as one of the major development activities needing a comperehensive management with both quantitative and qua...

Constructed wetlands are viable alternatives for the removal of multiple pollutants. The performance Sagittaria latifolia in free flowing and subsurface removing pollutants from domestic waters was evaluated. 12 will be followed, three with species without species, retention times 6.7 days 3.5 subsurface. presented an effluent turbidity 4.4±0.8 NTU, color 143.9±27.4 UC 33.9±25.7 mgL-1 COD. samp...

Techniques are available to minimize the concentration of asbestos fibers in drinking water. Filtration research conducted at locations on Lake Superior and in the Cascade Mountains in Washington has shown that amphibole and chrysotile fibers can be removed by granular media filtration. Removal percentages can exceed 99% when the raw water is coagulated properly and the filtered water turbidity...

Increase of impervious surfaces in urban area followed with increases in runoff volume and peak flow, leads to increase in urban storm water pollution. The polluted runoff has many adverse impacts on human life and environment. For that reason, the aim of this study was to investigate the efficiency of nano iron oxide coated sand with and without magnetic field in treatment of urban runoff. In ...

this study presents a comparison between aluminum and iron plate electrodes on phosphate removal from aqueous solutions by electrocoagulation process. the effectiveness of main operational parameters such as initial ph, initial phosphate concentration and current density were examined. in addition, treated solution and sludge characteristics, energy consumption and electrode mass depletion w...

Keggin-type aluminum-oxo polycations are effective coagulating agents for wastewater treatment. Previous work demonstrated that heteroatom substitution in ε-Al13 polycation leads to the formation of ε-GaAl12 and ε-GeAl12 can enhance removal bacteria, DOC, turbidity from wastewater. Additional hydrolysis species creates larger Al30 improves coagulation performance, but this aspect has not been e...

The present research investigates the ability of graphene oxide nanosheets for treatment of dairy wastewater, using In Situ Sludge Magnetic Impregnation” (ISSMI) to separate sludge after adsorption process. To increase the interaction between magnetic nanoparticles and graphene oxide, the former has been functionalized, using 3-Aminopropyl triethoxysilane, with the synthesized graphene oxide an...
