Paper mill sludge dewatering is a problem that compounds fast. Production variability shifts waste stream composition, biological treatment loads increase, and conventional presses like belt amd screw presses struggle to keep pace. Diamond T’s Alfa Laval centrifuge systems handle the streams that cause conventional equipment to foul or blind, reducing sludge volumes and recovering fiber before it leaves in the effluent.
Whether you need to rent or buy, Diamond T’s Alfa Laval centrifuge systems are specifically configured for paper industry applications. Our equipment handles what conventional technologies can’t, from challenging de-inking sludge with its abrasive particles to the biological waste that overwhelms traditional processes.
Unlike filter presses and settling systems, our centrifuges continuously process variable waste streams without fouling, blinding, or performance issues. Each system comes complete with custom-selected pumps, polymer dosing, and control systems matched to your specific waste characteristics, with availability in as little as 48 hours.

How dry is the output?
High DS
Drier output means less material to haul and dispose
Lower DS
Output quality degrades on difficult or variable streams
Moderate DS
Output quality drops as feed consistency changes
No Dewatering
Gravity settling only, output remains largely liquid
Does it handle changing waste streams?
Yes
Adjusts continuously to solids load
Partially
Feed variability causes clogging and manual intervention
Partially
Struggles on thin or dilute feeds
No
Only works on consistent, slow-settling material
Can it process de-inking sludge?
Yes
No internal filter media, so nothing clogs or wears out
Poor
Gritty particles clog and tear the filter belts
Poor
Gritty particles damage internal screens over time
Partially
Clay settles but dewatering is minimal
How much floor space does it need?
Compact
Self-contained skid that fits within existing facility footprints
Moderate
Belt wash and polymer systems add significant floor space
Compact
Similar footprint to a centrifuge
Very large
Acres of land
As Alfa Laval’s Master Distributor, Diamond T carries the full product line and configures systems specifically for paper industry applications.
That designation means access to the complete Alfa Laval decanter and solid bowl centrifuge range and the technical depth to match bowl geometry, polymer dosing, and pump selection to the specific demands of de-inking sludge, activated biological waste, or white water fiber recovery. We offer:
We deal with challenging slurries and tight product specs, so we needed a partner who understands process nuance, not just hardware. Diamond T brought cross-industry separation expertise that immediately improved our approach, and their team helped our operators understand the ‘why’ behind the settings. The equipment has been rock-solid, and their technical support is excellent.

Diamond T’s Alfa Laval centrifuge systems cover the full range of paper mill separation challenges, from fiber recovery in early-stage process water to difficult biological sludge at the back end of treatment.
We can assist with a wide range of applications, including:
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:
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:
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. For a detailed look at how centrifuges stack up against screw presses and filter presses across key performance criteria, see our equipment comparisons.
