For modern livestock farms, efficient manure management is becoming increasingly important. As farm scale continues to expand, traditional waste treatment methods are facing more pressure due to higher operating costs, environmental regulations and increasing sludge disposal requirements.

Many farm operators struggle with challenges such as:

• Excessive sediment accumulation in lagoons
• Frequent lagoon maintenance and cleaning
• High chemical consumption during wastewater treatment
• Large volumes of wet sludge after processing
• Rising costs for manure disposal and environmental management

A more efficient solution is to improve the separation process before manure enters the wastewater treatment system.

The Main Challenge: Excessive Solids Remaining in Liquid Manure

In many conventional manure treatment systems, raw manure usually passes through an initial solid-liquid separation stage before entering storage lagoons, biogas systems or further wastewater treatment processes.

However, after the first separation, the liquid fraction still contains a considerable amount of fine solids, fibers and suspended particles.

During long-term storage, these materials gradually settle at the bottom of lagoons, creating several operational problems:

• Reduced effective lagoon storage capacity
• Shorter cleaning intervals
• Increased labor and maintenance expenses
• Additional workload for downstream treatment equipment
• Higher demand for chemical treatment products

The higher the suspended solid concentration, the more difficult and expensive the following wastewater treatment process becomes.

Advanced Solution: Secondary Fine Filtration and Dewatering Process

To improve the overall efficiency of manure treatment systems, farms can introduce an additional fine separation and secondary dewatering process.

The optimized treatment process includes three key stages:

Step 1: Primary Solid-Liquid Separation

The first separation stage removes larger solid particles from fresh manure, reducing the load for the following treatment process.

Step 2: Fine Filtration Treatment

A secondary filtration process further removes smaller suspended particles and organic fibers, including fine materials that are difficult to separate during the first stage.

By reducing solid content in the liquid phase, the treated wastewater becomes easier to manage and more suitable for subsequent treatment.

Step 3: Secondary Screw Press Dewatering

The separated solid materials are transferred into a secondary screw press dewatering system for further moisture reduction.

This process improves solid recovery and produces a drier final material with better handling performance.

Benefits of Optimized Manure Treatment for Livestock Farms

By improving the separation process, farms can achieve significant operational advantages:

✔ Reduce sediment accumulation inside lagoons
✔ Extend lagoon cleaning intervals
✔ Decrease chemical consumption during wastewater treatment
✔ Reduce sludge production volume
✔ Lower manure disposal costs
✔ Improve wastewater treatment efficiency
✔ Enhance overall environmental performance

A more effective separation process at the beginning can greatly improve the performance of the entire manure management system.

Convert Livestock Waste into Valuable Agricultural Resources

After secondary dewatering, manure solids can achieve lower moisture content, making them easier to transport, store and process.

The treated organic material can be further utilized for:

• Organic fertilizer production
• Soil improvement materials
• Agricultural recycling applications
• Sustainable farming resource management

Instead of treating manure only as waste, farms can transform it into a valuable resource while reducing environmental pressure.
