Electrostatic Precipitation

ElectrostaticPrecipitation - Electrostatic precipitation is an efficient method of removing particles from air. In Litton large volume air sampler the air is allowed to pass through the electrodes.

The charged particles fall on a rotating disc which is fed with collecting fluid at a rate of 10ml per, minute. Air is sucked into the chamber by a rotating fan at the bottom. The low resistance of the system enables high rates of air flow. They are suitable for large volumes of air.

Luckiesh et al. devised a sampler which contains two removable covers. Each unit has one upper electrode and one lower electrode. In one unit the upper electrode is negative and the lower electrode is positive and in the other unit the electrical condition is reversed. Air is drawn at equal rates in both the units. Charged microorganisms are collected in the petridishes placed on opposite electrodes.
