Challenges of wastewater treatment in wood processing:

• High levels of organic matter (e.g., tannins, resins, lignin) – difficult to biodegrade

• Variable pH and temperature – inhibits microbial activity

• High suspended solids concentration – clogs conventional equipment

• Dark color (e.g., brown/black) – hard to remove via standard filtration

• Fluctuating flow rates – challenges system stability

• Sludge with poor settleability – requires efficient dewatering technology like Multi-disk Screw Press

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, ultimately allowing the collected filtrate to be recirculated or discharged.

Application Case in Wood Processing Sludge

Model: KTDL404 1 Set

Inlet Sludge: 98.2%

Outlet Mud Cake Moisture: 84% 

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.
