With the growth and development of chemical plants, the amount of mercury released in wastewater has increased. Mercury in wastewater contains harmful compounds which are hazardous to the human health and living organisms. Therefore, its removal from wastewater is significant. There are various techniques or methods available for removing mercury from aqueous solutions. This study focused upon ...

Abstract Introduction: Innovative processes for treatment of industrial effluents containing dyes and heavy metals are often used to reduce the toxicity of these compounds in order to reach the refining standards. Recently, a special focus on innovative processes took place for physical and chemical removal by new absorbent, biomass absorption, membrane filtration, radiation, and electrochemica...
Nickel and cadmium usually enter the environment and water resources through wastewater, released by various industries, and may have adverse effects. The current study employs α–Fe2O3 nanoparticles of 20-40 nm in order to remove nickel and cadmium from the wastewater of Saba Battery Company. Also, it investigates the influence of effective parameters on adsorption process, including pH, contac...
industrial wastewater included the dyes one of the important sources of environmental pollution that founded in loom wastewater which are harmful for human health and environment. therefore, the purpose of this research was investigated removal of rb5 dye from aqueous solution by using of adsorption onto activated red mud as an cheap adsorbent. this research was experimental- laboratorial study...
Present study dealt the removal of Cr(VI) in a tannery industry wastewater using rice husk silica powder as an adsorbent.The experimental investigations have been carried out by using rice husk silica powder for different adsorption dosage, different contact time and different pH against the initial Cr(VI) concentration of 292 mg/L. The maximum percentage removal of Cr(VI) in a tannery industri...
An overview is presented on the projects that are being carried out by Water Quality and Treatment Laboratory team of LNEC which use activated carbon based technologies for treating water or wastewater. Emphasis is given to the chemical enhancement of conventional wastewater treatment using “green” powdered activated carbon options, hybrid adsorption/ membrane processes or biologically active c...
Background and purpose: Magnetite hydroxyapatite (m-Hap) as a magnetic nano-adsorbent was synthesized for the removal of tetracycline (TC) from aqueous solutions. Materials and methods: The properties of m-Hap were investigated by scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR). Factors affecting the adsorption of TC including pH (3-10), adsorbent dosage...
in this work application of seven synthetic polymers as adsorbents for the removal of hg(ii) from aqueous solution was studied. the equilibrium studies are systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and ph of the aqueous solution. variations of hg(ii) concentration in solution have been studied through measur...
Alum sludge refers to the by-product from the processing of drinking water in water treatment works. In this study, groups of batch experiments were designed to identify the characteristics of dewatered alum sludge for phosphorus adsorption. Air-dried alum sludge (moisture content 10.2%), which was collected from a water treatment works in Dublin, was subjected to artificial P-rich wastewater a...
