Pig Manure Dewatering Machine

Pig manure dewatering machine is designed to separate the liquid and solid components of swine waste. Except for hog manure, it is also suitable for processing cow dung, duck manure, horse manure, and chicken manure. Tianzhong Machinery provides two reliable options for pig waste disposal: the screw press separator and the slope screen separator. These machines are capable of processing manure from 8 m³/h and up to 40 m³/h. With our dewatering solutions, you can efficiently manage and handle pig waste ensuring optimal waste separation and disposal. Please feel free to contact us for further information and details!

Slope screen separator is designed for separating low-solid and high-water content materials such as sewage, biogas slurry, and water flushed manure. For pig farms that employ flushing manure systems, we highly recommend choosing inclined screen separator. This device filters out the water from the mixture first, and then extrudes the solid waste by screw press separator.

Constructed from 304 stainless steel, this equipment offers exceptional corrosion resistance and durability. In addition, the screen mesh size and design are customizable according to the processing materials. Moreover, it also offers significant advantages in terms of high processing capacity, and ease of operation, making it an ideal option for large-scale farms. This machine find wide applications involving water flushing of feces, water-soaking of feces, and slaughterhouse wastewater treatment, slurry separation, etc.

Screw Press Dewatering Machine

However, for dry cleaning farms, it is recommended to choose the screw press separator. Below are more parameters for your reference.

The screw press separator is suitable for processing manure with large solid content and low water content. Its working process is as follows: The pig manure water is pumped into the screw machine by a pump. As the screw rotates, it moves the pig manure along the length of the machine. The pitch and design of the screw make the material to be compressed against the screen, gradually squeezing out the liquid.

With the increasing pressure, the water fliters out through the screen and drainage pipe; while retaining the solid particles. When the material is continuously pumped into the machine, the dewatered solid is compacted and pushed toward the outlet. Due to its high automation, low power consumption, and continuous operation, it is also popular in dewatering cow dung, processing spent grains, herb residues, biogas slurry, etc.

Advantages of Solid-liquid Separation of Pig Manure

Solid-liquid separation of pig manure offers numerous advantages, providing several benefits for livestock farms and the environment. Let’s take a closer look at these advantages:

1. It can effectively resolve the issue of sedimentation in biogas digesters, significantly enhancing their processing capacity.

2. The separated manure can be sold directly and the sale price will be much higher. But the processed pig manure is of excessive heavy metals. It can serve as raw material for organic fertilizers after fermentation.

3. After solid-liquid separation, the solid material is almost odorless.This reduction in odorous compounds effectively improves the air environment in the livestock farm.

4. The moisture content of the separated manure is about 60%, making it easier to store and transport to reduce the environmental pollution.


Managing pig manure is a significant challenge for farmers, but with the pig manure dewatering machine provided by Tianzhong Machinery, you can efficiently tackle this issue while enjoying numerous benefits. With our durable equipment and customizable solutions, you can confidently handle pig waste. Please contact us at Tianzhong Machinery for further information and details. Our team is ready to assist you in finding the perfect pig manure dewatering machine that suits your specific requirements and contributes to the success of your farm.
