Industrial Wastewater Treatment Stack Screw Press

The multi-disc screw sludge dewatering machine is a high-performance solid-liquid separation equipment. Through the internal spiral shaft rotation, sludge is pushed forward while moving rings maintain clear filter gaps. This process efficiently transforms fluid sludge into manageable sludge cakes.

This system integrates an electric control cabinet, flocculation mixing tank, and filtrate collection tank. It is especially effective for high oil content and organic sludge, ensuring stable dewatering with minimal power and water consumption.

Industrial Stack Screw Press
Typical Application Scenarios
Municipal Wastewater: Ideal for treating primary and secondary sedimentation tank sludge in medium-sized plants.
River Dredging: Handles highly viscous and sand-rich silt with on-site dewatering capabilities.
Food Processing: Manages organic sludge from breweries and slaughterhouses for fertilizer or biogas.
Chemical & Pharma: Designed for corrosive, oil-bearing, and high-concentration organic sludge.
Livestock Breeding: Treats manure for composting, solving odor and land occupation issues.
Core Strengths
1. High-Efficiency Reduction

Reduces moisture from 95% down to 60%–75%. Volume is cut to 1/3–1/5 of original size, significantly lowering transport costs.

2. Anti-Clogging Design

Alternating fixed and moving rings clear clogs automatically, allowing 24-hour unattended continuous operation.

3. Low Consumption

Uses 5%–20% of the energy required by centrifugal systems. Core components last over 8–10 years without consumables like filter cloths.
