An opposed migration classifier classifies particles suspended in a sample fluid that are passed through a classification channel defined by two permeable walls. Sample flow distribution input and output channels are located asymmetrically with respect to a center of the classification channel such that trajectories of the one or more particles in the sample fluid deviate from constant voltage operation trajectories. A cross-flow fluid enters the classification channel through a permeable wall and exits through the other permeable wall. An imposed field, created by a time varying filed imposed in a direction normal to the permeable walls, causes the particles to migrate in a direction opposite to that of the cross-flow fluid, such that the particles travel between the permeable walls. The particles in the sample are classified based on their mobility. The sample fluid enters and exists through or within a threshold distance of the permeable walls.

An electrostatic precipitator in one embodiment includes an outer housing defining an internal space, and a primary collector disposed therein which comprises a pair of nested inner and outer radial collecting walls. A collection annulus is formed between the walls which receives a flowing process gas stream. Electrodes within the annulus electrically charge particles entrained in the gas stream which electrostatically adhere to the collecting walls. In one embodiment, the collecting walls rotate through a stationary cleaning station in the housing which includes mechanical devices such as scrapers to automatically and mechanically remove the collected particles from the walls. The devices may be vertical drag chains with scrapers coupled thereto in one embodiment. The precipitator may be a wet electrostatic precipitator which treats an incoming wetted gas stream. The precipitator is especially adapted to remove sticky type particulate from the collecting walls.
