Method for obtaining dissolved suspended or chemically bound substances from a liquid

摘要

A method and apparatus for obtaining dissolved, suspended or chemically bound substances from a liquid by passing the liquid upwardly through a bed of adsorbent particles in an upwardly extending channel, the liquid flow rate being such that the particles are fluidized and the liquid flowing initially through a device providing a resistance to flow whereby the flow is stabilized and the particles move slowly within the flow through the channel.
