Pulp & Paper Solutions

Turn Wasted Fibers into Recovered Revenue

Paper mills face constant pressure to reduce waste-handling costs while meeting increasingly strict environmental regulations. Diamond T’s centrifuge systems rise to the challenge with superior dewatering performance that reduces sludge volumes and handles difficult-to-process streams before they overwhelm belt and screw presses.

Pulp & Paper Applications

As liquid-solid separation experts, Diamond T provides field-proven centrifuge technology that makes pulp and paper waste management more efficient and cost-effective. We help reduce disposal costs, recover valuable fibers, and support environmental compliance goals.

We can assist with a wide range of applications, including:

  • White water (process water containing fine fibers) recovery and reuse
  • Primary and secondary sludge dewatering
  • De-inking waste processing and volume reduction
  • Biological treatment sludge management
  • Coating waste recovery and dewatering
  • Settling pond replacement and footprint reduction
  • Lime mud and chemical recovery stream dewatering
  • Discharge quality improvement
  • Clarifier underflow concentration and processing

Pulp & Paper Solutions FAQs

What is fiber recovery, and why does it matter for paper operations?

Fiber recovery captures valuable materials lost in wastewater streams, generating immediate economic and environmental benefits. Recovering short fibers from white water and process streams reduces raw material costs, cuts disposal volumes, simplifies permit compliance, and demonstrates environmental stewardship.

Many paper mill waste streams contain recoverable materials with real market value when properly separated and processed. For instance:

  • De-inking operations recover clay and coating materials for beneficial reuse
  • Primary clarification sludge yields recoverable fibers for lower-grade products
  • Biological treatment solids become soil amendments or fertilizer products
  • Lime mud from chemical recovery processes can be reclaimed and reused

The key is separation technology that produces consistent, properly dried products that meet quality standards.

Paper mills employ various approaches for waste treatment and volume reduction:

  • Settling ponds and clarification systems
  • Save-alls and disk filters for fiber capture
  • Belt filter presses and screw presses
  • Gravity thickeners and flotation units
  • Chemical treatment and flocculation
  • Vacuum filters and rotary systems
  • Membrane filtration technologies

Centrifuges overcome the limitations of traditional systems: enclosed processing prevents odors, continuous operation handles variable streams, and drier solids reduce disposal costs while enabling reuse. Compared to presses or settling systems, centrifuges offer faster processing, smaller footprints, and reliable performance with difficult biological sludges.

Our paper industry systems feature Alfa Laval’s industrial centrifuge technology, integrated with complete process support equipment:

  • High-performance decanter centrifuges with paper-specific modifications

  • Technical service support and operator training programs

Centrifuge-based solutions address the operational and financial challenges your mill faces, including:

  • Substantially lower disposal costs through major volume reduction
  • Improved recovery of valuable fibers from process streams
  • Effective dewatering of difficult biological treatment sludges
  • Continuous automated operation requiring minimal operator attention
  • Stable, reliable performance despite changing waste characteristics
  • Compact equipment footprint compared to settling basins or filter presses
  • Capability to process mixed sludges that defeat conventional equipment
  • Consistent discharge quality ensuring permit compliance
  • Rapid installation compared to constructing permanent treatment infrastructure

Absolutely. Every system is configured to handle your specific waste characteristics, including composition, solids content, fiber types, chemical properties, and flow rates. We analyze waste samples, select the appropriate centrifuge models, and optimize operating parameters to deliver the dewatering performance and discharge quality required for your operation, ensuring cost-effective disposal and compliance.
