Two-phase stirred tank reactor simulation using Open®

Description: The stirred tank reactor in this tutorial has a cylindrical shell with inner diameter of 0.4 m and height of 0.35 m. The bottom cap is a 2:1 ellipse (radius1 is 0.2 m and radius2 is 0.1 m) and top of this cylinder is open to atmosphere. A four-bladed impeller is located in the middle of the reactor to provide the mixing force.

The initial MLSS and current ranged from 2–6 g/L and 50–600 mA, respectively. In continuous EF experiments, cylindrical reactors (2 L) were first filled with 5 mM of NaCl before introducing mixed liquor upon the potential bias. The effluent was collected from the reactor bottom to evaluate the separation efficiency based on SS concentration.

Froth Flotation Process - Detailed Explanation With ...

Froth flotation has been used in coal and mineral cleaning operation for a long time. It is based on the difference in densities of materials. Normally, air bubbles are forced into the tank using external aerators or agitators, these tiny bubbles attaches to the surface of algal cells and by buoyancy, the cells are risen up in the tank.

Structural Design of Tank Weighing Systems | HBM

The overall load should also be distributed as evenly as possible over the three load cells. In the case of upright or suspended cylindrical tanks, the best way to meet this requirement is if the three load cells are arranged at equal distances from the vertical axis of the tank and are offset from each other by 120° on the same plane.
