Hazards Identification and the Units Assessment of a the Water Treatment Plant Against Pathogenic and Biotoxin Threats Affecting by Physicochemical Parameters

A. Bahramian

Volume 17, Issue 4 , October 2020, , Pages 33-48

http://dx.doi.org/10.22034/ijche.2020.130360

Abstract
  In this study, the inactivation performance of units against pathogenic and biotoxin threats in a water treatment plant is studied. The assessment of the units and hazards of the water treatment plant against each of threats is studied by the RAMCAP risk analysis. The experiments showed that the Aflatoxin ...  Read More

Bubble formation on a single orifice in a gas solid fluidized bed using digital image analysis

A. Dehghan Lotfabad; S. Movahedirad; M.T. Sadeghi

Volume 13, Issue 1 , January 2016, , Pages 60-72

Abstract
  Digital Image Analysis (DIA) has been employed to characterize the time evolution of a bubble injected from a single orifice into a pseudo 2-dimansional gas-solid fluidized bed. The injected bubble diameter increased with the square root of time before detachment. During bubble free flight in the bed, ...  Read More

Sh. Mehmandoust; M. R. Moghbeli1*; M. Dadban; H. Karimian

Volume 12, Issue 3 , July 2015, , Pages 41-54

Abstract
  "> Sodium montmorillonite (Na-MMT) was organically modified using 11- aminoundecanoic acid (AUA) and methacryloxyethyltrimethylammonium chloride (MAETAC) via cation exchange reaction. The effect of the modifier type and concentration on the structure and surface properties of the organically modified ...  Read More

Study on the Effect of Humidity on Electrical Properties of Copper-Silica Aerogel

N. Yasrebi; J. Moghaddas

Volume 12, Issue 2 , April 2015, , Pages 3-12

Abstract
  > Copper-silica aerogel was synthesized by the sol-gel method and was heated at 400, 500 and 600°C for 3 h in the air. The gained materials were named as sample (a), (b) and (c) respectively. Then all samples were characterized by FE-SEM, EDX and FTIR spectroscopy. For resistance measurements ...  Read More

Optimization of Integrated Low-Temperature Gas Separation Processes Using SA Method and Different Refrigerants
Volume 6, Issue 4 , October 2009, , Pages 27-33

Abstract
  In low-temperature processes, heat rejected from separation columns is removed by refrigeration systems to heat sinks (reboilers & pre-heaters), process streams, other refrigeration streams, or external utilities. The need for efficient utilization and recovery of energy in sub-ambient gas separation ...  Read More

Study of Carbon Black Production with Optimized Feed to Predict Product Particle Size
Volume 4, Issue 1 , January 2007, , Pages 36-42

Abstract
  Carbon black or soot is a carbon rich material which is widely used as a modifier and filler. Usually carbon black is produced via thermal decomposition of heavy hydrocarbons. This process is too complex to be modelled fundamentally. In this study, the effect of reaction feed composition on the soot ...  Read More

Synthesis and Seeding Time Effect on the Performance of Nanostructure Sodalite Membranes
Volume 4, Issue 1 , January 2007, , Pages 54-70

Abstract
  > Secondary growth technique was successfully applied for the synthesis of nanostructure sodalite membranes with vacuum seeding on tubular α-Al2O3 supports. In the seeding process, a thin, uniform and continuous seeding layer was closely attached to the support external surface by the pressure ...  Read More

A Study of Flow and Mixing in Bubbly Gas-Liquid Pipe Flow Generated by a Grid
Volume 3, Issue 4 , October 2006, , Pages 60-75

Abstract
  The spreading of a tracer in a bubbly two-phase grid-generated turbulent flow system is studied. In this work both particle image velocimetry (PIV) and planer laser-induced fluorescence (PLIF) are used to study the effect of the dispersed phase flow rate on the mixing characteristics of the tracer. The ...  Read More

A Detailed Investigation of Particulate Dispersion from Kerman Cement Plant
Volume 3, Issue 3 , July 2006, , Pages 65-74

Abstract
  The aim of this study was to investigate the particulate dispersion from Kerman Cement Plant. The upwind – downwind method was used to measure particle concentration and a cascade impactor was applied to determine particle size distribution. An Eulerian model, Gaussian plume model and an artificial ...  Read More
