environmental effects of gol-e-gohar iron ore mine on groundwater of the area
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Desorption by Ultrasound: Phenol on Activated Carbon and Polymeric Resin
An experimental feasibility study of using ultrasound to accomplish the dificult desorption of phenol from activated carbon and polymeric resin adsorbents is discussed. The desorption rates of activated carbon were found to significantly increase by ultrasound at 40 kHz and 1.44 MHz. Attrition of the activated carbon due to cavitation could be prevented by operating at a higher frequency and wi...
متن کاملA Novel Photovoltaic Powered Reverse Osmosis with Improved Productivity of Reverse Osmosis and Photovoltaic Panel
With the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. Domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. The novel concept of photovoltaic powered ...
متن کاملThe Elimination of Toluenediamine from Aqueous Solution by Reverse Osmosis
Toluene diamine (TDA) is a main carcinogenic aromatic pollutant in some industrial wastewater. In this study, the reverse osmosis with DSS-HR98PP as the membrane was employed for the removal of TDA in an aqueous environment. The Box–Behnken Design (BBD) of the experimentwas used to consider the effect of operational variables such as pressure, pH and the feed volu...
متن کاملRemoval of assimilable organic carbon and biodegradable dissolved organic carbon by reverse osmosis and nanofiltration membranes
The main objective of this study was to evaluate the effectiveness of reverse osmosis (RO) and nanofiltration (NF), under various solution chemistries, on bacterial regrowth potential as quantified by assimilable organic carbon (AOC) and biodegradable dissolved organic carbon (BDOC). The bench-scale experiments, using tap groundwater spiked with acetate as organic carbon, revealed that AOC remo...
