GN Company Report about Comparison of Centrifuge and Filter Press

 

 

 

1. Continuous Operation + Labor Intensity + Automation Degree

1.1 Decanter Centrifuge 

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.
