------------------------------------------------- Treatment of industrial wastewater The various types of contamination of wastewater require a variety of strategies to remove the contamination Brine treatment Brine treatment involves removing dissolved salt ions from the waste stream. Although similarities to seawater or brackish water desalination exist‚ industrial brine treatment may contain unique combinations of dissolved ions‚ such as hardness ions or other metals‚ necessitating specific

MATLAB BASED AUTOMATED CONTROL SIMULATIONS IN BIO-REACTORS ABSTRACT Designing of bioreactors is a very complex process and requires the clear understanding of the biological phenomena occurring during the process and the development of best suitable reactor for bringing out the product in an economically viable‚ large scale form. The conventional techniques currently in uses are very time consuming and some of their steps may even be based on trial and error format. Therefore there

Continuum Percolation study of carbon nano tube composites via Size distribution effects. A.Afaghi ;S.Asiaei ;M.Baniasadi Mechanical engineering department;University of Tehran. The three-dimensional continuum percolation problem of hard-core and soft-core (permeable) objects was an area of active research in the 1980s[1]. Among the considered geometrical objects a very important category is the case of permeable sticks with the form of capped cylinders [2]. Advancements in capabilities of

“Global pollution creates a “public bad” born by all – a negative externality with a wide impact” (M.Harris‚ 2002). Australia is considered to be the driest populated continent in the world and faces stern drought and water shortages. Reducing carbon emissions is challenging for Australia‚ although the Government realizes that meeting this challenge is important and commits to reducing the level of pollution caused by greenhouse gases in Australia‚ and voluntarily preparing for an altered climate

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but
