A pressure consumption regenerating filter

A separator suitable for separating solid material from a fluid, the separator comprising:

• a chamber with an inlet and an outlet,
• a sieve structure forming a permeable barrier between the inlet and the outlet to filter the fluid, the sieve structure thus having an inlet side for unfiltered fluid and an outlet side for filtered fluid,
• the separator further comprising a filter pressure regeneration apparatus for dislodging filtered material from the sieve structure,
• wherein the filter pressure regeneration apparatus comprises a conduit and a nozzle assembly having at least one cleaning nozzle for directing cleaning fluid towards the outlet side of the sieve structure to dislodge filtered material from the inlet side of the sieve structure,
• wherein the chamber includes a channel formed of the chamber wall and the sieve structure and wherein the inlet is located at an end of the channel such that in use the fluid flows through the channel and the material dislodged by cleaning fluid from the cleaning nozzle is swept towards the other end of the channel away from the inlet by the movement of the fluid
• wherein the sieve structure has a circular cross-section and is located within the chamber and wherein the inlet is arranged to direct fluid tangentially into the chamber onto the sieve structure and a wall is provided to one side of the inlet such that the fluid is guided circumferentially around the sieve structure through the channel such that filtered material dislodged by the cleaning fluid from the cleaning nozzle is swept around the chamber by the flow of the fluid and accumulates on the side of the wall away from the inlet.
