Product Description

Product Overview

Our industrial decanter centrifuge is a state-of-the-art, continuous-operation separator engineered specifically for demanding wastewater treatment and sludge dewatering applications. It is designed to efficiently reduce sludge volume, lower disposal costs, and produce clear effluent for reuse or safe discharge. Built for reliability and performance in municipal sewage plants and various industrial facilities, this machine is your key to a more efficient and economical operation.

• Key Features & Advantages

• Superior Separation Efficiency: Achieves excellent solids capture rates (typically >95%), producing a dry solids cake and clear centrate, significantly reducing sludge volume and disposal costs.

• Fully Automatic & Continuous Operation: Ensures 24/7 uninterrupted processing with minimal operator intervention, leading to higher productivity and lower labor costs.

• Robust Construction: Critical parts are manufactured from high-grade stainless steel (304/316L) or duplex steel, offering exceptional corrosion resistance and long service life in harsh environments.

• Energy-Saving Design: Optimized hydrodynamic design and efficient drive systems result in lower power consumption compared to traditional filter presses.

• Low Operational Costs: Minimal maintenance requirements and no need for filter cloths or consumables, ensuring a low total cost of ownership.

• Adaptable Performance: Adjustable bowl speed and differential speed allow for precise control over cake dryness and centrate clarity to handle varying feed conditions.

• Compact Footprint: Vertical design requires significantly less floor space than conventional settling tanks or filter press systems.

• Applications

   

• Municipal Wastewater Treatment Plants: Dewatering of primary, secondary (activated), and mixed sludges.

• Industrial Wastewater Treatment:

  • Food & Beverage: Processing of slaughterhouse, dairy, brewery, and food processing waste.

  • Chemical & Pharmaceutical: Separation of chemical by-products and pharmaceutical residues.

  • Petrochemical/Oil & Gas: Treatment of oily sludge and API separator underflow.

  • Pulp & Paper: Dewatering of pulp residues and paper mill sludge.

  • Textile & Dyeing: Treatment of dye-containing wastewater and sludge.
     

    How It Works

  • Feed: The slurry (sludge) is introduced into the rotating bowl through a stationary feed pipe.

  • Separation: Under the influence of high centrifugal force (G-force), denser solid particles are forced outward against the bowl wall, while the less dense liquid (centrate) forms an inner layer.

  • Conveying: A helical scroll (conveyor), rotating at a slightly different speed, gently conveys the settled solids towards the conical end of the bowl.

  • Dewatering: As solids move forward, they are further dehydrated in the "beach" section before being discharged.

  • Discharge: The dewatered solids (cake) are ejected from the solids discharge ports, while the clarified liquid overflows weirs at the large end of the bowl.
