Challenges of treating biogas sludge:

• High initial moisture content – Sludge often exceeds 95–98% water, making volume reduction energy?intensive and costly.
• Variable solids concentration – Fluctuations from <0.2% to >4% solids challenge conventional dewatering equipment, causing clogging or inefficient operation.
• Complex organic composition – Contains residual fibers, fats, and inorganic grit that can wear parts and interfere with flocculation.

Multi-disk Screw Press:
Integrates an automatic control cabinet, sludge thickening and dewatering unit, and a liquid collection tank. Under fully automatic operation, it enables efficient flocculation and continuous sludge thickening and dewatering, allowing the collected filtrate to be recirculated or discharged.

Application Case in biogas sludge project:

Model: KTDL404 1 Set

Inlet Sludge Moisture: 98.6%

Outlet Mud Cake Moisture: 82%

Advantages:
- Small footprint
- Low energy consumption, not prone to clogging, and capable of handling various sludge concentrations: traditional equipment cannot process low-concentration sludge, is easily clogged, and has high energy consumption. Screw press: low energy consumption, less than 5% of a centrifuge. Self-cleaning and not easily clogged. Capable of handling solid concentrations from <0.2% to >4%.
- Water saving: less than 0.1% of a belt press
- Automatic program control: 24-hour unattended automatic operation
- Low running speed, vibration & noise: less abrasion, long lifespan.
