The Decanter Centrifuge for Dairy Sludge Dewatering and Separation continuously separates dairy wastewater sludge solids from liquid during milk processing and dairy wastewater treatment.

It is suitable for dairy plant sludge, activated sludge, milk processing wastewater, cheese production wastewater, and biological treatment sludge applications.

Dairy sludge usually contains high organic content, fine suspended solids, variable concentration, and high moisture content, which make traditional dewatering processes difficult. The decanter centrifuge provides continuous solid-liquid separation to reduce sludge volume and improve handling efficiency.

• Dairy wastewater sludge dewatering
• Milk processing wastewater treatment
• Cheese factory sludge separation
• Yogurt production wastewater treatment
• Activated sludge concentration
• Biological sludge dewatering
• Dairy plant solid recovery
• Process water clarification

High Organic Load

Dairy sludge contains proteins, fats, lactose residues, and organic matter, which increase treatment difficulty and sludge disposal cost.

Fine Suspended Solids

Small particles and biological solids are difficult to settle naturally, resulting in poor clarification efficiency.

High Moisture Content

Dairy sludge usually contains a large amount of water, increasing transportation and disposal costs.

Variable Sludge Characteristics

Feed concentration, viscosity, and solid content may change with different dairy production processes.

Grease and Fat Content

Residual oil and fat can affect separation performance and require suitable operating adjustment.

Continuous Wastewater Treatment Demand

Large dairy plants require stable, automatic operation with minimal maintenance.

Dairy Wastewater Sludge
→ Screening
→ Sludge Conditioning
→ Feed Tank
→ Decanter Centrifuge
→ Dewatered Sludge Cake + Clarified Water

Dewatered Sludge Cake → Disposal / Composting / Further Treatment

Clarified Water → Biological Treatment / Recycling
