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
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.

1. Continuous Operation + Labor Intensity + Automation Degree
It works continuously, and has low requirement for labor workers, and highly automatic, and simple operation. When the feed concentration changes, the slip and torque of the drum and screw will automatically track and adjust
One operate worker can manage 2 to 3 units at the same time.
1.2 Filter Press
It works Not continuously, and operation is complicated, and technical requirement is high, because when the feed concentration changes, the dosing amount, and flushing water pressure all shall be adjusted
It's working procedure as follow.
Firstly, feeding sewage until then it is full.
Secondly, pressing and squeezing water out.
Thirdly, unload the sludge cake.
Fourthly, repeat the 3 steps above.
Generally, two operate workers operate 1 unit. The labor intensity is high and working environment is poor, so welfare and wage requirement for Operating workers are relatively high.
2. Energy Consumption (Electricity + Water)
2.1 Electricity
Decanter electricity cost is some higher than Filter.
For example,
17m3/hour capacity,
Decanter Power is
Filter Press Power is
2.2 Water
Water Flushing for clean is not necessary during continuous operation of Decanter.
Only if Decanter stops working for long hours, it's better to clean with water, normal pressure, 10~15minutes is Okay.
Water Flushing for clean is Necessary for Filter every day!
At least 60~70m3 water shall be used for flushing. The waste flushing water shall be collected Sedimentation Tank for further treatment.
Note:
The filter cloth of Filter Press shall be clean regularly during operation; otherwise it will affect dewatering performance of filter press. This takes much time and labor effort.
