摘要： The invention relates to a method and an apparatus for the gravitational separation of fine particles out of a liquid. The liquid containing the particles which are to be separated is conducted with laminar flow through the gaps between a plurality of closely separated, essentially horizontally orientated surface-forming elements (16). The liquid flow through the gaps is interrupted when the particle concentration in the liquid which has flowed through the gaps exceeds a predetermined value. The surface-forming elements (16) are repositioned to an essentially vertical discharging position in order to remove the particle collection present on the surface-forming elements. The surface-forming elements (16) are then returned to the essentially horizontal working position and a new gravitational separation cycle begins.

摘要： A device and a process for centrifugal separation of solid particles from a liquid is disclosed. The device comprises a vessel rotatable around a vertical axis. The vessel has a separation zone with separation surface elements. The separation surface elements are formed by a plurality of adjacent, axially oriented tubular elements or channels open at both ends. The process is characterized in that the liquid is caused to flow with essentially laminar flow through a plurality of axially oriented, parallel channels and is subjected to a g-number, preferably less than 100, in order to centrifugally deposit the particles on the channel walls.

摘要： Method and arrangement for filtering particles out of a liquid, in which the liquid containing particles is supplied to a sedimentation tank (12), and the liquid is made, by means of hydrostatic liquid pressure prevailing in the tank, to flow through a filter member (18) on the shell surface of a drum (14) mounted in the tank (12). When the liquid in the tank has risen to a predetermined level above the drum (14) as a result of clogging of the filter member (18), cleaning of the filter member (18) in situ in the tank is initiated.

摘要： Method and arrangement for continuous filtering of particles out of a contaminated liquid by means of a number of separate filtering units (14) in order continuously to feed purified liquid to a consumer. Each filtering unit (14) comprises a rotatable, perforated drum (16) with a particle-catching filter means (18) on the outer surface of the drum. A first predetermined degree of coating with particles is created on the filter means of the drums, and purified liquid inside all the drums of the filtering units (14) except at least one, which is kept inactive in a standby state by shutting off the associated pump (26), is then fed to a consumer. The feed of purified liquid from a drum to the consumer is interrupted when a second predetermined, higher degree of coating with particles has been reached on the filter means on an individual drum, at least one filtering unit kept in standby state being activated as replacement for the filtering unit(s) from which the feed of purified liquid has been interrupted. The filter means of each filtering unit shut down is cleaned, and liquid in the tank is made to pass through the cleaned filter means and to circulate back to the tank until the first predetermined degree of coating with particles has been reached on the filter means of the drum. The cleaned shut-down filtering unit is put in a standby state by shutting off its pump. The second, higher degree of coating is detected by means of a respective pressure sensor coordinated with each filtrate outlet pipe (24).
