Introducing the Screw Sludge Dewatering Machine

Our screw sludge dewatering machine leverages a unique screw press mechanism to deliver unmatched efficiency and reliability. Designed for biogas facilities, municipal wastewater plants, and agricultural operations, this machine transforms high-moisture sludge into compact, dry cakes with moisture content as low as 65–75%.

How It Works

The process begins when sludge is fed into the machine’s inlet. A rotating screw shaft gradually conveys the material through a cylindrical screen. As the sludge travels, increasing pressure forces water out through the screen, while the compacted solids are discharged from the outlet. The closed-loop system ensures minimal odor release—a key advantage for environmentally sensitive sites.

Key Features & Advantages

Superior Dewatering Efficiency

Achieves 20–35% higher dryness compared to conventional methods.

Handles diverse sludge types (organic, municipal, industrial) with adjustable pressure settings.

Energy-Saving Design

Low power consumption due to gravity-driven drainage and optimized screw rotation.

Reduces operational costs by up to 40% versus centrifugal systems.

Durability & Corrosion Resistance

Constructed with high-quality stainless steel and enamel-coated components (a hallmark of Center Enamel’s expertise), ensuring longevity in harsh, corrosive environments.

Automation & Ease of Use

PLC-controlled system allows for real-time monitoring and adjustments.

Low maintenance requirements with self-cleaning screens and minimal wear parts.

Eco-Friendly Operation

Reduces sludge volume, cutting transportation and disposal emissions.

Odor containment supports compliance with environmental regulations.
