Abstract
Disclosed herein is a method of collecting suspensions in a liquid film including the steps of developing a variation in surface tension at a gas-liquid interface of the liquid film to generate a circulating flow pattern within the liquid film, and scanning the liquid film with the circulating flow pattern for entrapment of the suspensions in the flow pattern by re-directing the variation in the surface tension across the gas-liquid interface of the liquid film.
