Removal of Cr from synthetic wastewater by sorption into volcanic ash soil
Tel.: +66-2 986 9009 (ext.2307); Fax: +66-2 986-9009 ext 2301 ABSTRACT: The possibility of using volcanic ash soils (VAS) or Andisols as a low-cost and natural adsorbent is investigated in this study for the removal of Cr (VI) from synthetic wastewater. Andisols can be used as adsorbent because they are characterized by the presence of non-crystalline secondary minerals such as allophane and im...
متن کاملSimultaneous Ash and Sulphur Removal from Bitumen Using Column Flotation Technique: Experiments, RSM Modeling and Optimization
An efficient method was employed for the ash and pyrite sulphur removal from bitumen using column flotation process. The bitumen samples containing 9.6% sulphur (6.81% in the pyrite sulphur form) and 26.4% ash were successfully showed up to 75.20% of pyrite sulphur (e.g.; 51.66% of total sulphur) and 70.81% of ash removal. The Box-Behnken Design (BBD) was employed to design the experiments, to ...
متن کاملRemoval Processes of Volcanic Ash Particles from the Atmosphere
INTRODUCTION The use of satellite techniques provides valuable information for mapping ash hazards, as well as the means to study and predict the fates of volcanic clouds. We have used ultraviolet (TOMS – Total Ozone Mapping Spectrometer) and infrared (e.g., AVHRR – Advanced Very High Resolution Radiometer; HIRS2 – High Resolution Infrared Radiation Sounder/2; GOES – Geostationary Operational E...
متن کاملAsh and sulphur removal from bitumen using column flotation technique: Experimental and response surface methodology modeling
This study investigates removing ash and pyrite sulphur from bitumen by column flotation process. Central composite design (CCD) of response surface methodology (RSM) was applied for modeling and optimization of the percentage of ash and pyrite sulphur removal from bitumen. The effects of five parameters namely the amounts of collector and frother agents, particle size, wash water rate and feed...
