 · As lab manual said, aim of this lab was to investigate the flotation response of quartz using anionic and cationic collectors. As we know, the Point of Zero Charge (PZC) for quartz occurs at a pH between 2.7 and 3.0. Above this pH quartz is negatively charged and below it is positively charged.

dissolved air flotation - an overview | ScienceDirect Topics

Flotation depends on the interaction between microalgal cells and air bubbles. Because both air bubbles and microalgal cells are negatively charged, they do not interact, and flotation generally does not work well for harvesting microalgae unless additives are used (Garg et al., 2012).

1 Froth Flotation – Fundamental Principles

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

 · Flotation experiments were carried out using a columnar 150 ml flotation cell (45 mm in diameter and 100 mm in height). There is a porous gas diffusor with a nominal pore diameter placing at the column bottom, just above the gas inlet port. Dispersed air bubbles (approx. 700 µm) were generated from an air blower through the diffusor.

The selective flotation of alkali halide salts such as KCl and NaCl is of great industrial significance and has been considered by flotation chemists for many decades.

How Does A Float Charger Work? - batteryfloatchargers.com

A float charger (also called a storage charger, maintenance charger, or smart charger) will charge a battery at a similar rate as a battery self-discharges, thus maintaining a full capacity battery. However, the main difference between a trickle charger and a float charger is that a float charger has circuitry to prevent battery overcharging.
