How to Choose the Right Amalgam Separator for Your Dental Practice?

How to Choose the Right Amalgam Separator for Your Dental Practice?

September 25, 2026

Choosing the right amalgam separator is an important consideration for dental practices that use dental amalgam or remove restorations containing amalgam. The right system needs to match the practice's suction arrangement, number of surgeries, installation requirements, and approach to dental amalgam waste.

For UK dental practices, separator selection is not simply about buying the largest or most advanced unit. The better approach is to understand how the practice handles wastewater and suction, then choose a system designed for that application.

QUDENT provides a range of amalgam separation solutions for different dental practice requirements, including standalone separators, sink-connected models and systems designed for central suction.

What Is an Amalgam Separator?

An amalgam separator is a device designed to retain and collect amalgam particles from wastewater generated in dental practices. It is installed within the relevant waste or suction system so that amalgam-containing particles can be separated before wastewater leaves the practice.

In the UK, the requirements surrounding dental amalgam are linked to mercury-control legislation. Article 10 of Regulation (EU) 2017/852 requires relevant dental facilities to use amalgam separators capable of retaining at least 95% of amalgam particles, with maintenance carried out according to the manufacturer's instructions.

The exact installation and waste-management arrangements should therefore be considered alongside the separator itself.

How Does Amalgam Separation Work?

Different separator designs use different methods, but the basic principle is straightforward: amalgam particles are captured from wastewater rather than being allowed to pass directly into the drainage system.

For example, the Alvaley separators available from QUDENT use a sedimentary and filtration process. The manufacturer information states that these systems can remove up to 96.6% of amalgam particulates from the wastewater stream.

The suitability of a particular separator depends on how the dental practice generates and moves wastewater.

Key factors that affect selection

  • Number of dental surgeries
  • Type of suction system
  • Whether the unit connects to a sink or waste line
  • Available installation space
  • Gravity or pumped waste arrangements
  • Required capacity
  • Manufacturer maintenance and replacement instructions
  • Waste collection arrangements

A separator should be selected for the actual workflow rather than simply based on its size or purchase price.

How to Choose an Amalgam Separator for Your Practice?

1. Consider the Number of Surgeries

The number of surgeries using the system is one of the first things to establish.

A single-surgery dental practice may need a compact separator intended for one surgery, while a larger practice with a central suction system may require a model designed for multiple surgeries.

For example, QUDENT's Alvaley Amalgam Separator Size One is designed for a single-surgery setup. It is compact, requires no electrical power and is supplied with a self-installation kit.

For practices with a central suction arrangement, the Alvaley Wet Amalgam Separator Size Two is designed for use with central suction serving two or three surgeries. The product information also states that it can be used with pumped waste and gravity drains.

2. Check Your Suction and Waste Configuration

Not every separator is intended for the same installation.

Before purchasing, identify whether your practice uses:

  • Individual surgery suction
  • Central suction
  • A mobile aspirator
  • Gravity drainage
  • Pumped waste
  • Sink-connected waste

This information can significantly narrow down the suitable options.

For example, the Alvaley Amalgam Separator Size 1 for Sink is specifically designed to connect to sinks used with mobile aspirators or for general amalgam waste.

If your existing setup is unclear, check the dental unit and suction manufacturer's installation requirements before ordering.

3. Consider Available Installation Space

Dental surgeries can have limited space around suction and drainage equipment. A compact separator may therefore be more practical where installation space is restricted.

The Alvaley Size One measures 210 mm × 250 mm, while the Size Two model measures 450 mm × 250 mm.

These dimensions should be checked against the actual installation area before purchasing.

4. Understand the Separation Method

Understanding how the system separates amalgam can help you compare suitable products.

Sedimentation and filtration systems, such as the Alvaley models, separate particles from the wastewater stream using physical processes. The Size One and Size Two product information describes these units as non-electrical systems with no rotors or collector cups.

Other dental systems may use different separation technologies or integrate amalgam separation with suction equipment. The important consideration is whether the selected system is appropriate for your practice and applicable requirements.

5. Check Maintenance and Replacement Requirements

A separator is part of a waste-management process, so buying the unit is only one part of the process.

The relevant UK mercury regulation states that amalgam separators should be maintained according to the manufacturer's instructions to achieve the highest practicable retention level.

The Alvaley product information states that its Size One and Size Two models require no maintenance or servicing and have stated usage periods before recycling.

Always follow the specific manufacturer's instructions rather than if every dental amalgam separator has the same maintenance schedule.

Advantages and Limitations to Consider

Potential advantages

  • Helps retain amalgam particles from dental wastewater
  • Can support compliance with applicable requirements
  • Options are available for different surgery configurations
  • Some systems require no electrical power
  • Compact designs can suit restricted installation areas
  • Integrated options can be considered where suction and amalgam separation need to work together

Potential limitations

  • Not every separator suits every suction system
  • Installation dimensions must be checked
  • Larger practices may require a system designed for central suction
  • Waste collection and disposal remain part of the overall process
  • Maintenance or replacement requirements vary between manufacturers

The goal is therefore not to find a universally "best" separator, but to identify the system that matches the practice's actual setup.

Dental Amalgam Waste: What Practices Should Consider

Amalgam separation is only one part of responsible dental amalgam waste management.

UK requirements state that dental amalgam waste must be handled and collected by an authorised waste-management establishment or undertaking, and amalgam waste must not be released directly or indirectly into the environment.

For permitted healthcare-waste facilities in England, dental amalgam is identified as a separate waste stream for storage and handling.

Practices should therefore consider the complete process:

  1. Capture amalgam particles through an appropriate separator.
  2. Follow the manufacturer's instructions for the separator.
  3. Collect amalgam-related waste appropriately.
  4. Use an authorised waste-management service where required.
  5. Keep relevant waste-management procedures and records.

Requirements can vary across the UK, so practices should check the rules applicable to their nation and local arrangements.

Common Mistakes When Buying an Amalgam Separator

Choosing based only on price

The lowest purchase price does not necessarily mean the best fit. Installation compatibility, capacity, waste arrangements and ongoing requirements should all be considered.

Ignoring the suction configuration

A separator designed for one surgery may not be appropriate for a central suction system serving multiple surgeries.

Forgetting installation dimensions

Measure the available area before ordering. This is particularly important in compact surgeries or when replacing an existing separator.

Assuming every separator works the same way

Separation technology, capacity, connections and maintenance requirements can differ. Always review the product specifications and manufacturer's instructions.

Treating the separator as the entire waste-management solution

A separator helps with particle retention, but the practice still needs an appropriate process for handling and transferring amalgam waste.

Which Amalgam Separator Is Right for You?

The best starting point is to match the separator to your practice configuration.

For a single surgery, a compact model such as the Alvaley Size One amalgam separator may be worth considering based on its stated single-surgery application.

For a sink-connected application involving a mobile aspirator or general amalgam waste, the Alvaley Size 1 for Sink is specifically described for that purpose.

For a practice using central suction for two or three surgeries, the Alvaley Wet Amalgam Separator Size Two is designed for that configuration.

Expert Buying Checklist

Before ordering an amalgam separator, confirm:

  • Number of surgeries: How many treatment rooms will use the system?
  • Suction type: Is it individual, mobile or central suction?
  • Waste connection: Does the separator match the existing pipework?
  • Installation: Is there sufficient physical space?
  • Capacity: Is the model appropriate for the expected workload?
  • Separation method: Do you understand how the selected system operates?
  • Maintenance: What does the manufacturer require?
  • Waste handling: How will collected amalgam waste be managed?
  • Regulatory requirements: Does the installation meet the requirements applicable to your location?

Taking a few minutes to confirm these points can prevent an unsuitable purchase and reduce installation complications.

Conclusion
