摘要： There is described a separator 2 for separating solids from a liquid, the separator 2 comprising: a hydrodynamic separator 100; a first filtration device 200, 600, the first filtration device 200, 600 comprising a first inlet 55, 655 at a first level A1 for receiving at least a first portion of the liquid from the hydrodynamic separator 100 and a first filter 48, 648 for filtering the first portion of the liquid received via the first inlet 55, 655, wherein during filtration of the first portion of the liquid, the first portion of the liquid passes through the first filter 48, 648 away from the first inlet 55, 655 and a first portion of solids is retained by the first filter 48, 648; a first backwash device 300, 900, wherein the first filter 48, 648 is located between the first inlet 55, 655 and the first backwash device 300, 900, wherein the first backwash device 300, 900 is configured to alternately prevent and allow the passage of the first portion of the liquid through the first backwash device 300, 900 such that, when the passage of the first portion of the liquid through the first backwash device 300, 900 is prevented, the first portion of the liquid that has passed through the first filter 48, 648 passes back through the first filter 48, 648 toward the first inlet 55, 655 so as to remove the first portion of solids from the first filter 48, 648; a second filtration device 400, 700, the second filtration device 400, 700 comprising a second inlet 455, 755 at a second level A2 higher than the first level A1 for receiving a second portion of the liquid from the hydrodynamic separator 100 and a second filter 448, 748 for filtering the second portion of the liquid received via the second inlet 455, 755, wherein during filtration of the second portion of the liquid, the second portion of the liquid passes through the second filter 448, 748 away from the second inlet 455, 755 and a second portion of solids is retained by the second filter 448, 748; and a second backwash device 500, 800, 900, wherein the second filter 448, 748 is located between the second inlet 455, 755 and the second backwash device 500, 800, 900, wherein the second backwash device 500, 800, 900 is configured to alternately prevent and allow the passage of the second portion of the liquid through the second backwash device 500, 800, 900 such that, when the passage of the second portion of the liquid through the second backwash device 500, 800, 900 is prevented, the second portion of the liquid that has passed through the second filter 448, 748 passes back through the second filter 448, 748 toward the second inlet 455, 755 so as to remove the second portion of solids from the second filter 448, 748.
