Regarding to the Clients’ questions about the Comparison of Centrifuge and Filter Press, GN Company Technical Team had research and prepared report, details as follow.

1. Installation + Footprint

1.1 Decanter Centrifuge

Decanter is compact structure, and easy to install, commissioning and operate.

The supporting equipment is only Polymer Dosing device + sludge feed pump + discharge conveyor.

The whole machine is fully sealed, and good for workshop environment.

1.2 Filter Press

Filter takes up large area.

And supporting equipment is Polymer Dosing device + sludge feed pump + discharge conveyor + flush pumps + air compressors + sludge conditioners, etc.

Filter is open operation, and the whole machine is poor sealing.

There is high pressure cleaning water mist, and there is also Odor polluting environment.

If management is not good, it will cause mud overflow.

1.3 Space Requirement

Filter required installation space is 2~3 times than Decanter Centrifuge.

Decanter shall be better for some clients, where their work plant area is limited.

2. Maintenance

2.1 Decanter Centrifuge

Decanter is fully sealed, and only a few wearing parts, such as V-belt, Bearing, which can be easy find from local market.

2.2 Filter Press

Filter Press has many wearing parts.

Due to the characteristics of open operation, the rotating shaft, gears, bearings and filter belts are corroded by sewage seriously, which is easy to get damaged, and shall always be replacement.

If feed pressure is too high, the filter cloth will be easily damaged and the filter plate will be deformed.
