Dolphin Centrifuge publishes industrial centrifuge case studies documenting real-world separation performance, ROI, and system design decisions. Case studies cover diesel fuel recovery, waste oil processing, coolant reclamation, marine fuel treatment, and more — with documented savings figures and installation details.
Case Studies
Each case study below documents a real centrifuge installation with measured results — throughput rates, output quality, and return on investment. These projects use disc stack centrifuges and decanter centrifuges supplied by Dolphin Centrifuge.

Frequently Asked Questions
+ What industries are covered in Dolphin Centrifuge case studies?
Dolphin Centrifuge case studies cover waste oil recovery (marine and industrial), used oil re-refining, semiconductor/silicon wafer wastewater treatment, pyrolysis oil purification from tire recycling, and municipal wastewater sludge dewatering. Each case study includes real throughput figures, before-and-after separation quality data, and ROI information.
+ How much waste oil can a Dolphin Centrifuge system process?
Dolphin Centrifuge systems have been installed in facilities ranging from small 5-GPM skid systems to large-scale 6-million-gallon-per-year used oil processing plants. The 6 MGY used oil plant case study documents a multi-centrifuge installation with staged processing for meeting re-refinery input specifications.
+ Can a centrifuge process pyrolysis oil from tire recycling?
Yes. Disc stack centrifuges effectively remove carbon black, metals, and water from pyrolysis oil produced by waste tire recycling (TDP/pyrolysis). The cleaned pyrolysis oil can be sold as fuel oil or used as a diesel substitute. Dolphin Centrifuge has documented case studies for pyrolysis oil purification using self-cleaning disc stack centrifuge systems.
+ How does a centrifuge treat silicon wafer manufacturing wastewater?
Silicon wafer polishing and cutting processes generate wastewater with very fine silicon fines suspended in water. Disc stack centrifuges at up to 10,000 G remove these submicron particles, producing clarified water suitable for reuse and a concentrated silicon solids cake for disposal or recovery. This eliminates filter press bottlenecks and reduces waste disposal costs.
+ Where can I find centrifuge FAQ resources for general questions?
Dolphin Centrifuge publishes two comprehensive FAQ pages: the Disc Stack Centrifuge FAQ (/disc-stack-centrifuge-faq/) covering how disc stack centrifuges work, maintenance requirements, and applications; and the Industrial Centrifuge FAQ (/industrial-centrifuges-faq/) covering general centrifuge selection, operating principles, and cost considerations across all centrifuge types.
