Wastewater decanter DDE series

for water treatment applicationsindustrialfor sludge dewatering

Product
Decanter centrifuge DDE Series features a 2-phase horizontal rotating bowl, continuous sludge discharge via a scrolling conveyor and a dual-drive design with variable differential speed. The machine is engineered for efficient solid-liquid separation in municipal and industrial wastewater treatment and potable water applications.

Application Areas
Suitable for municipal wastewater plants, industrial effluent treatment and potable water treatment facilities. The DDE Series separates suspended solids, increases sludge dryness and lowers disposal volume and costs.

Advanced Design & Competitive Solution
Designed for both large-scale and small/medium-capacity installations, the DDE Series offers an economical separation solution using advanced manufacturing and modular configuration options.

Continuous Processing Capability
Capable of continuous operation on low to high solids loads, the decanter extracts the majority of suspended solids and delivers significantly drier sludge for more efficient handling and disposal.

Performance Benefits

• Maximum solid extraction from wastewater streams
• Enhanced sludge dryness up to 30% solids (depending on feed and configuration)
• Reduced disposal volume and costs by minimizing water content
• Continuous, uninterrupted operation for reliable plant performance
• Energy-efficient processing via optimized motor control and VFDs
