Production of Pure Nano-Iron by Using Ball Milling Machine, Chemical Batch Reactor and K-M Micro Reactor

Semi-batch Chemical Reactor

Control of complex nonlinear systems brings challenges in the controller design. One of methods how to cope with this challenge is the usage of advanced optimization methods. This work presents application of self-organizing migrating algorithm (SOMA) in control of the semi-batch reactor. The reactor is used in chromium recycling process in leather industry. Because of the complexity of this se...

Hydrothermal Production of Highly Pure Nano Pyrite in a Stirred Reactor

In this study, pyrite was produced by hydrothermal precipitation from the reaction between FeSO4 and Na2S2O3 at high pressure and high temperature in a stirred reactor. The solid product was purified by means of solvent extraction to remove sulfur. Powder was characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and thermal ...

Review of Micro-Particles of Hydroxyapatite Nanoparticles by Ball Milling

Hydroxyapatite (HA) is the most important bioactive ceramics because of biocompatibility and structural similarity to the mineral part of bones and teeth of broad clinical application in the field of dentistry, orthopedic and coatings are Biomaterials. The aim of this study was to construct nano-hydroxyapatite micro particles using calcite, silica and zinc oxide using ball milling, powder, thes...

Sequencing Batch Reactor Systems

The sequencing batch reactor (SBR) process is a sequential suspended growth (activated sludge) process in which all major steps occur in the same tank in sequential order (figure 1). There are two major classifications of SBRs: the intermittent flow (IF) or “true batch reactor,” which employs all the steps in figure 1, and the continuous flow (CF) system, which does not follow these steps. Both...
