Wastewater Management in Dental Laboratories: Efficient Sedimentation Solutions
In a dental prosthetics laboratory, managing wastewater generated from milling, polishing, grinding, and adjustment procedures represents a regulatory, technical, and environmental challenge. Water loaded with plaster, metal residues, ceramics, or investment materials cannot be discharged directly into drainage systems without proper treatment.
Installing a sedimentation system is now the most reliable solution for effectively separating heavy particles, protecting plumbing infrastructure, and ensuring long-term laboratory performance.
Why is sedimentation essential in dental laboratories?
Residues generated by prosthetic work have high density and a strong tendency to settle within pipes. Without a sedimentation device, these particles quickly cause blockages, malfunctions, and costly maintenance interventions.
A sedimentation tank slows down water flow, promoting the natural settling of heavy particles before clarified water is discharged. This simple principle provides a robust, proven solution perfectly suited to the daily constraints of dental laboratories.
Important: a sedimentation tank is not suitable for paint, oil, or grease deposits. These lighter-than-water materials cannot be effectively separated through sedimentation.
Why is sedimentation essential?
Residues from milling, polishing, and grinding processes are highly dense and rapidly settle inside drainage systems.
Without a sedimentation tank, these particles lead to clogging, breakdowns, and expensive repairs.
Operating principle
The sedimentation tank slows water flow to encourage natural particle settling.
Clarified water is discharged while sludge remains trapped, ensuring a simple, reliable, and durable laboratory solution.
Before installation
Important: a sedimentation tank is not designed for oils, grease, or paints.
As these substances are lighter than water, they cannot be treated through sedimentation.
Key selection criteria
- capacity suited to activity volume,
- compatibility with treated residues,
- controlled maintenance frequency,
- easy installation under workbenches.
How to choose a sedimentation tank?
- Capacity: tank volume must match usage intensity and the number of workstations generating wastewater.
- Residue type: plaster, polishing sludge, metal particles, or composites require progressive and efficient sedimentation.
- Maintenance frequency: larger capacity extends cleaning intervals and limits production downtime.
- Integration: the system must be easily installed under worktops or near equipment.

Best practices for use and maintenance
To ensure optimal efficiency, it is recommended to:
- adapt tank capacity to actual laboratory activity,
- perform regular sludge removal based on collected residue volume,
- avoid direct discharge of incompatible materials,
- use flocculation agents if necessary to improve sedimentation.
Rigorous wastewater management not only ensures regulatory compliance but also contributes to the long-term durability of installations and daily working comfort for dental technicians by significantly reducing the risk of workflow interruptions caused by flooding of laboratory premises or shared building areas.
