Introduction: The Powdered Activated Carbon Treatment (PACT) has been proposed as an alternative in wastewater treatment and wastewater biomass protection against toxic substances. This study aims to evaluate PACT performance in treating dyes, acid orange, and remazol brilliant reactive blue. Materials and Methods: This empirical- applied research was carried out in pilot scale in which differ...

Direct Red 81, a dye widely used in textile industries, is frequently detected dye in water resources. High costs, the formation of hazardous byproducts, and high energy costs restrict the use of some removal methods. Therefore, the main objectives of this research are the feasibility of using soil containing iron as a low cost adsorbent to remove (Direct Red 81) from aqueo...

Background and purpose: Textile industries are among the most polluting industries regarding the volume and the complexity of treatment of its effluents discharge. This study investigated the efficiency of electrocoagulation process using aluminum electrodes in basic red 18 dye removal from aqueous solutions. Materials and Methods: This study was performed in a bipolar batch reactor with ...

synthetic dyes are among the most common contaminants of the environment. therefore, the aim of this study was investigation the removal of basic blue 41 (bb41) and methylene blue (mb) from industrial effluents by useing raw and modified rice stems. in this study raw and modified rice stems treated chemically with citric acid (ca) and were used to explore the potentiality of rice stems for remo...

Background: Electro-oxidation is developed as an electrochemical method to overcome the problems of  the conventional  decolorization technologies and is an appropriate alternative for the treatment of colored wastewater from various industries. The purpose of this study was to evaluate the efficiency of the electrochemical oxidation process in  removal  of chemical oxygen demand (COD) and Acid...

the clay crosslinked hydrogel nanocomposites were synthesized by graft copolymerization of acrylamide and itaconic acid in the presence of different amounts of laponite using ammonium persulfate and n,n,n',n'-tetramethylethylene diamine  )temed) as a free radical initiator and catalyst, respectively. the xrd patterns of nanocomposites showed that the clay layers are completely exfolia...

In this research, the efficiency of electrocoagulation treatment process using iron and aluminum electrodes to treat synthetic wastewater containing Reactive Red 24 (RR 24) was studied. The effects of parameters such as current density, pH, type of electrolyte, initial dye concentration, electrolyte concentration, temperature, and inter electrode distance on dye removal efficiency were investig...
