Why Invest In A Screw Press Slurry Separator?

At Tianzhong Machinery, we offer a highly efficient dewatering machine that utilizes a screw press technology to extract water from slurry and achieve solid-liquid separation. For the slurry with water content over 90%, we also provide a slope screen separator as an alternative option.

Dewatering biogas slurry plays a crucial role in biogas production and waste management.

Benefits of Dewatering Biogas Slurry

Reducing Volume and Costs
Biogas slurry contains a large amount of water, which makes it expensive to transport and store. By dewatering the slurry, the water content is reduced, resulting in a smaller volume and lower transportation costs.
Turning Waste to Valuable Products
Biogas slurry is rich in nutrients such as nitrogen, phosphorus, and potassium, which are beneficial for plant growth. Dewatered biogas slurry can be used as fertilizer directly or be further processed into organic fertilizer. This higher nutrient content enhances its market value, bringing higher economic benefits for investors.
Improving Biogas Production
Dewatering the slurry can have positive impacts on the biogas production process. The solids content is increased by removing the excess water, resulting in a more concentrated substrate for anaerobic digestion. This can enhance the microbial activity, improve biogas yields, and increase the overall efficiency of the biogas plant.
Minimizing Odor and Environmental Risks
Biogas slurry often produces strong odors due to organic matter and microbial activity. Dewatering the slurry reduces the water content, which can help to control odor emissions. Additionally, it can minimize the risk of nutrient runoff and leaching into water bodies, thereby reducing the potential for water pollution.

Overall, dewatering biogas slurry offers various benefits. It contributes to the efficient and sustainable operation of biogas plants while minimizing environmental impacts. If you are interested, please contact us for more details.

Working Process of Biogas Slurry Dewater Machine

The biogas slurry is pumped into the dewatering machine, where it undergoes mechanical squeezing and filtration processes. Inside the dewatering machine, the slurry moves through the machine. As the screw turns, the pressure increases gradually. Then the liquid is squeezed out of the screen and discharged through an outlet. While the solid component is retained and compressed. And the dewatered cake is finally discharged at the end of the screw press. Below is a video for your reference. You can find more videos from our YouTube.

What to Consider Before Purchasing Slurry Dewatering Machine?

Before buying a biogas slurry dewatering machine, there are several key factors you should consider:

Please consider the characteristics of the slurry you will be working with, such as the solid content, water content, particle size, viscosity, etc. This information will help you select a suitable dewatering method and screen opening size.

It is necessary to know the volume of slurry you need to process per day. We will recommend you the model to ensure it can handle your desired workload according to how many tons or cubic metres of slurry to process per hour or per day.

Consider the machine’s dimensions, including height, width, and length, to ensure it can fit into your facility or operational area. Please inform us ofyour available space and we will offer a drawing layout to ensure that the machine can be installed and operated comfortably in your area.

Research the reputation of the manufacturers or suppliers regarding their customer support, after-sales service, and technical assistance. At Tianzhong Machinery, we provide technical support, spare parts availability, installation, training services, etc.

Evaluate the initial purchase cost and cost of operation, including maintenance, spare parts, and energy consumption. Compare the costs with the expected benefits and savings, you will choose a machine which fits your budget and specific needs.


Investing in a biogas slurry dewatering machine from Tianzhong Machinery offers numerous advantages. It is benefical for improving biogas production and waste management. By reducing the moisture content and volume of biogas slurry, this equipment helps lower transportation and space costs. It is also able to improve biogas yields and overall biogas plant efficiency. Moreover, the dewatered slurry can be used directly as fertilizer or processed into organic fertilizer, providing economic benefits.
