Sludge Recovery

AEKS delivers high-efficiency sludge dewatering and recovery solutions using advanced 2-phase and 3-phase decanter centrifuge systems, designed specifically for the treatment of complex and heavily loaded industrial sludges. These systems are essential in handling oily sludge, separator residues, tank bottom sediments, and other high-solid content waste streams generated in sectors such as refining, petrochemical, food & beverage, metal processing, and pharmaceutical production.

Decanter Technology & Capabilities

Our decanter centrifuges operate on the principle of centrifugal sedimentation, enabling continuous, high-throughput separation of mixed-phase waste streams into:

• Solid cake: Dewatered solids suitable for stabilization or disposal
• Aqueous phase: Recovered process water for potential reuse or compliant discharge
• Oil phase (3-phase only): Separated hydrocarbons which can be reprocessed or sent for energy recovery

AEKS’s systems are engineered for flexibility, allowing real-time adjustment of G-force, differential speed, and feed rate, ensuring optimal performance across a wide range of viscosities, densities, and feed characteristics.

Mobile Deployment & On-Site Processing

Our mobile decanter units are containerized for plug-and-play deployment and are fully self-contained with:

• Automated feed pumps and control panels
• Integrated chemical dosing skids (e.g., polymers, coagulants) for enhanced separation efficiency
• Sludge buffer tanks and flow meters for batch or continuous operation

These mobile units enable on-site sludge minimization, significantly reducing transport volumes, disposal costs, and operational downtime—making them ideal for shutdowns, tank cleanouts, and emergency environmental responses.

Recovered Materials Handling

• Oil Phase: Separated hydrocarbons may be sent to licensed recovery facilities for reuse, refining, or thermal valorization
• Water Phase: May be treated further to meet discharge or recycling specifications, depending on composition
• Solid Phase: Stabilized using lime, cementitious binders, or encapsulation techniques before disposal at approved landfill or incineration routes

All outputs are managed in compliance with national waste codes, ADR transport rules, and EU waste hierarchy principles.

Regulatory & Documentation Framework

Each sludge recovery operation is conducted under GDP-compliant documentation with:

• Pre-treatment sludge characterization
• Full traceability of recovered phases and disposal routes
• Final treatment certificates and environmental performance reports

AEKS ensures that every tonne of sludge is treated, tracked, and transferred with full transparency, providing clients with confidence in both performance and regulatory alignment.
