Mestra decantation tanks — controlled wastewater management for dental laboratories

In a dental laboratory or clinic, managing wastewater and particles generated during prosthetic work is an essential technical and hygiene requirement.

The Mestra decantation tanks ensure efficient separation of heavy residues such as plaster, pumice, sludge and polishing particles, while making daily maintenance easier.

The dental decantation tank is an essential piece of equipment in dental laboratories for managing wastewater loaded with plaster, resin and particles generated by polishing work. Mestra solutions provide efficient sludge sedimentation, helping to prevent pipe clogging and supporting compliance with environmental requirements.

Suitable for under-sink or workshop installation, these decantation systems ensure optimal separation of solid particles and simplified maintenance thanks to accessible compartments and collection bags.

Protection

Helps prevent pipe clogging by retaining heavy particles before discharge.

Capacity

Several capacities are available to suit both small workstations and high-activity laboratories.

Maintenance

Simplified maintenance thanks to clear sedimentation and clean recovery of residues.

Products in the Mestra range

Mestra decantation tank 14 L

Compact 14-litre unit, suitable for small laboratories or individual workstations with reliable sedimentation.

Mestra decantation tank 19 L

Intermediate capacity, ideal for regular activity, with a good balance between volume and maintenance.

Mestra decantation tank 70 L

Large-capacity solution for intensive environments, helping to reduce maintenance frequency.

Flocculant for decantation tank

A useful accessory to simplify maintenance and improve recovery of sedimented residues.

How to choose your decantation system

Suitable capacity

Choose the volume according to your working pace and the type of workstation.

Maintenance

A higher capacity reduces emptying frequency but requires more available space.

Hygiene and compliance

Make sure the system matches your laboratory wastewater management requirements.

How a decantation tank works

The operation of a decantation tank for dental laboratories is based on gravity sedimentation. Wastewater loaded with plaster, sludge or solid particles slows down through several compartments.

Heavy residues settle at the bottom of the tank while clearer water continues towards the drain, helping to protect pipework and maintain clean management of laboratory wastewater.

Particle separation
Plaster and sludge residues settle at the bottom.

Slowed circulation
Water passes through several sedimentation compartments.

Simplified maintenance
Deposits can be removed regularly.

Applications in dental laboratories

Plaster trimming workstations

Polishing and grinding areas

Cleaning of dental impressions

FAQ — Decantation tank for dental laboratories

Why install a decantation tank in a dental laboratory?

In a dental laboratory, plaster trimming, polishing and cleaning operations generate solid residues.

A decantation tank slows down the water flow so that heavy particles settle before discharge.

How does a decantation tank for plaster work?

The principle is based on gravity sedimentation. Water loaded with plaster slows down in the tank, particles settle in the compartments, and clearer water is discharged.

What decantation tank capacity should I choose for a dental laboratory?

For an individual workstation, a tank of around 14 litres is often sufficient.

For heavier activity, a larger capacity reduces cleaning frequency.

How often should a decantation tank be maintained?

Regular checking of sludge and residue levels is recommended.

Periodic maintenance helps maintain efficient wastewater management and prevents pipe clogging.

Lab tip: regular maintenance and emptying adapted to your activity ensure efficient sedimentation and a long-lasting installation.
