introduction activated sludge process is one of the most common methods used in wastewater treatment plants. regarding the large volume of sludge obtained from such biological wastewater treatment processes and considerable costs of its treatment and disposal, extensive research has been and is being done on novel effective methods of sludge stabilization. in previous investigations research gr...
the saline tannery wastewater also contains the high concentration of organic materials and various chemical compounds like lime, sodium sulfite, sulfate ammonium, sodium chloride, disinfections, vegetable tannins, salts of chromium and chloride. in recent years different applications of advanced oxidation processes (aops) are applied to remove organic loading (cod) from wastewater. advanced ox...
several laundry houses throughout tehran consume a large amount of water each day and discharge the resulting wastewater into septic tanks or municipal sewage system without any suitable pretreatment. this would result in severe contamination and other serious environmental issues. in the present study, performance of electrocoagulation/flotation process with aluminum and iron electrodes is com...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
introduction wastewater treatment using activated sludge process (asp) produces huge amounts of sludge that must be treated by efficient methods. wastewater sludge handling is one of the most important economic-technical challenges of wastewater treatment projects. conventional methods for this purpose are very time consuming, expensive and in lots of cases have limited success. in ...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
Background and Objective: Electrochemical methods as one of the advanced oxidation processes (AOPs), have been applied effectively to degrade recalcitrant organics in aqueous solutions. In the present work, the performance of electro-Fenton (EF) method using iron electrodes on the degradation of phenol was studied. Materials and Methods: In this study, a lab-scale EF batch reactor equipped with...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
Background and purpose: Nitrate contamination in aqueous solution has become an increasingly serious environmental problem. Hence, in this study removal of nitrate in aqueous solution was reviewed using electrocoagulation (EC) and electro-fenton (EF) processes for Fe electrodes. Materials and methods: In the present study, an EC and EF reactor in a lab scale to an approximate volume of 1 liter...
