A quenching system can be as simple as spraying liquid into the duct just preceding the main scrubbing vessel, or it can be a separate chamber (or tower) with its own spray system identical to a spray tower. Quenchers are designed using the same principles as scrubbers. Increasing the gas-liquid contact in them increases their operational ...
Temperature of the cleaning solution. Elevating the temperature of a cleaning solution increases its dirt removal efficiency. Molecules with high kinetic energy dislodge dirt faster than the slow moving molecules of a cold solution. Concentration of the cleaning agent. A concentrated cleaning solution will clean a dirty surface much better than ...

CADR measures the amount of filtered air circulated during a short period of time, and was originally designed to rate media-based air cleaners. The Sharper Image claimed that this test was a poor way to rate the Ionic Breeze, since it does not take into account other features, such as 24-hour-a-day continuous cleaning, ease of maintenance, and ...
