In manure-based bio organic fertilizer production, controlling moisture content is the first and most decisive step. Excess water not only slows down composting and fermentation but also increases energy consumption in downstream processing. This is why choosing the right manure dewatering machine is essential for building a stable and cost-effective organic fertilizer production line.
Below are four widely used manure dewatering solutions commonly integrated into modern biofertilizer plants.
- Screw Press Manure Dewatering Machine
The screw press separator is one of the most widely adopted manure solid-liquid separation machines in organic fertilizer projects. It uses mechanical extrusion to remove free water from livestock manure.
This type of organic manure dewatering equipment is suitable for chicken manure, cow dung, pig manure, and biogas slurry. It is valued for its simple structure, low energy consumption, and easy maintenance, making it ideal for small to medium-scale bio organic fertilizer production lines.
- Multi-Disc Screw Dewatering Machine (Stacked Screw Press)
The multi-disc screw dewatering machine, also known as a stacked screw sludge dewatering system, is increasingly popular in modern fertilizer plants. It operates continuously with low rotational speed, reducing wear and clogging.
Compared with traditional dewatering equipment, this manure dewatering system performs well with low-concentration manure and mixed organic waste. Its compact design, automatic operation, and low noise level make it suitable for farms and integrated biofertilizer production facilities with limited space.
- Centrifugal Manure Dewatering Equipment
A decanter centrifuge separates solids and liquids through high-speed centrifugal force. This advanced manure dewatering machine is often used when higher separation efficiency is required or when manure contains fine particles.
Although the investment cost is higher, centrifugal dewatering equipment provides stable output and consistent moisture control, especially in large-scale organic fertilizer manufacturing plants.
- Inclined Screen Separator for Pre-Dewatering
Inclined screen separators are commonly used as a pre-dewatering solution. They remove free water and coarse solids before further dehydration stages, reducing the load on downstream manure dewatering machines.
This type of separator is often installed at the front end of a bio organic fertilizer processing line to improve overall efficiency and system stability. Click here to get more!
From Dewatered Manure to Bio Organic Fertilizer
After dewatering, manure moisture is typically reduced to around 30–45%, making it suitable for composting, fermentation, or granulation. The dewatered material can then be processed through:
Composting systems or fermentation tanks
Crushers and mixers for material conditioning
Biofertilizer granulation lines to produce organic fertilizer pellets
