Understand the roles of the screw shaft, fixed rings, moving rings, filtration gaps, drive, washing system, inlet, filtrate, and discharge.
Screw shaft and drive
The drive rotates the screw at its designed speed. The screw transports sludge from inlet to discharge while helping develop gradual pressure.
Fixed and moving rings
The ring assembly forms filtration gaps. Relative movement of the moving rings helps clean those gaps during operation, while washing and inspection remain necessary.
Flocculation and feed section
Conditioned sludge enters with flocs that need to remain intact. Excessive mixing or feed changes can affect separation in the screw section.
Filtrate, washing, and discharge
Separated water is collected through filtrate paths, sprays rinse the filtration area, and cake exits at the end. Each path should be kept free of blockage and leakage.
