Manure Solid-Liquid Separation at 30-50 m3/h: Scope and Honest Limits

Livestock wastewater physical separation reduces load at the front of the treatment line; it is not discharge treatment. This article explains how an inclined screen, high-frequency fine screen and volute screw press recover solids at a reference 30–50 m³/h and where the process boundary sits.

Event background

Pig and cattle manure carry high moisture and suspended solids. Sending that load straight into biological or chemical treatment increases scale and operating cost. Physical separation first recovers compostable solids and shrinks the downstream treatment burden.

Key facts

• The inclined screen removes coarse fiber and large particles and protects downstream units.
• The high-frequency fine screen uses a reference 0.3 mm / 150-mesh stainless screen and a reference treatment rate of 30–50 m³/h.
• At reference conditions the fine screen achieves roughly 95% solids interception.
• The volute screw press dewaters concentrated solids; separated solids can go to composting while liquid continues to existing storage or treatment.
• The system includes collection and homogenization with a manure pump and control package for consistent flow.
• This is physical solid-liquid separation and suspended-solids reduction, not a substitute for biological or chemical treatment to discharge standards.
• Configurations are matched to animal type, flow, TS/SS and fiber content.

What this means for customers

The buyer treats the wastewater problem and the fertilizer opportunity together: recovered solids become organic-fertilizer feedstock while the liquid's suspended-solids load drops, allowing a smaller downstream treatment design.

How we support this

YUSHUNXIN configures a two-stage separation train by animal type, flow, TS/SS and fiber content, and states clearly that it does not replace biological or chemical polishing.

Next steps

Provide animal type, collection method, flow, TS/SS and the intended destination for recovered solids. We will return a separation configuration and the boundary of what the equipment can and cannot do.
