Background: Highly-concentrated phosphate and nitrate anions from sugarcane wastewater are often discharged into public waters without standardized treatments. This study assessed the effects of electrical coagulation, initial pH and reaction time in the removal of phosphate and nitrate pollutants. Methods: We used aluminum electrodes to remove the pollutants at Hakhim Farabi Agricultural and ...

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 were...

background: phosphorus is an indispensable element for the growth of animals and plants. there are several environmental problems related to phosphate; therefore, the technical and economic methods of removing phosphate are of great importance. this study evaluated the efficiency of polyaniline/ni0.5zn0.5fe2o4 magnetic nanocomposite in removing phosphate from aqueous environments. methods: the ...

background: the effective size of the end grain of horizontal roughing filters (hrfs) is larger than 2 mm. this study aimed to examine the efficiency of hrfs in removing nitrate, phosphate, and chemical oxygen demand (cod) from effluent of a wastewater stabilization pond. methods: this experimental study was conducted in 2013. the pilot project was transferred to the karaj wastewater treatment ...

the aim of this study was to evaluate the ability of microalgae spirulina platensis and chlorella vulgaris to remove nitrate and phosphate in aqueous solutions. spirulina platensis and chlorella vulgar is microalgae was collected in 1000 ml of municipal water and kno3, k2hpo4 was added as sources of nitrate and phosphate in three different concentrations (0.25, 0.35 and 0.45g/l). during the gro...
