How to solve the water content problem of Screw Type Sludge Dehydrator？

Generally speaking, limited by the principle of the Screw Type Sludge Dehydrator and the current technological level, the water content of the sludge treated by the Screw Type Sludge Dehydrator is generally between 80% and 85%. Different types of sludge may be There will be a slight difference, but generally, it will not be less than 70% (the moisture content of sludge solidification is 50%~60%). The moisture content of the Screw Type Sludge Dehydrator is too high. What causes it? How to reduce the water content of the Screw Type Sludge Dehydrator?

The following is a list of contents:

1. Reasons for high moisture content

2. How to reduce the moisture content

Reasons for high water content

Objective reasons

The nature of the sludge: the nature of the sludge is the objective reason, what type of sludge, the organic content in the sludge, whether the sludge is chemical or municipal? These are all determined by the nature of the sludge. Different types of sludge do affect the moisture content of the Screw Type Sludge Dehydrator after dehydration.

Process reasons

1. The manufacturer's manufacturing process is not up to standard: To cut corners and materials, some manufacturers fail to manufacture the Screw Type Sludge Dehydrator, which affects the sludge dewatering rate to a certain extent.

2. The manufacturer fails to meet the standard of flocculation in debugging: wrong or inaccurate selection of flocculant results in poor flocculation effect, which affects the moisture content of the Screw Type Sludge Dehydrator after dewatering to a certain extent.

3. The manufacturer’s machine setting is not up to standard: the Screw Type Sludge Dehydrator is a fully automatic product controlled by a PLC electrical cabinet. When setting the machine to run, pay attention to setting the machine's spiral operating parameters and adjusting the gap of the backpressure plate.

How to reduce the moisture content

Given the high water content of sludge, how to reduce the water content?

1. Reduce the organic content of the sludge: For the objective reasons of the sludge, the organic content in the sludge should be tested and the organic content should be reduced because the organic matter is too hydrophilic for the sludge, resulting in low dehydration efficiency and too viscous Should not be handled.

2. Optimizing manufacturers and suppliers: Choose domestic excellent Screw Type Sludge Dehydrator manufacturers to pass the test on the length of the screw shaft and technical parameters.

3. Automatic dosing device: integrated intelligent dosing device, the manufacturer configures the flocculant and adjusts the dosing amount and dosing frequency speed.

4. Set spiral operating parameters: It mainly includes speed adjustment. Too fast or too slow will cause the slurry to be concentrated and squeezed too early or too late, which will affect the dehydration efficiency of the Screw Type Sludge Dehydrator.

5. Adjust the gap of the backpressure plate: Generally, it should not exceed 4mm. Too tight or too loose will affect the dewatering efficiency of the Screw Type Sludge Dehydrator. It should be adjusted by the manufacturer.

6. Other external factors: please adjust according to actual conditions.
